Official Atmel AVR development tools and evaluation kits contain a number of starter kits and debugging tools with support for most AVR devices. Hi Avinash, Thank you for this really nice and good software. My student already built the hardware (USBasp) and installed the eXtreme Burner software (I will also do.

Avrdude is a command line program, so you'll have to type in all the commands (later you'll find out how to shortcut this with a Makefile) Under Windows, you'll need to open up a command window, select Run. From the Start Menu and type in cmd and hit OK. Under MacOS X, you can use the Terminal program to pull up a command line interface, its in the Utilities folder Now in the new terminal window type in avrdude you should get this response, which is basically a simple list of what avrdude can do.

There are a lot of options, lets review them quickly. Don't try to memorize them, just get a sense of what some of them may do.p: This is just to tell it what microcontroller its programming. For example, if you are programming an ATtiny2313, use attiny2313 as the partnumber.b: This is for overriding the serial baud rate for programmers like the STK500. Don't use this switch, the default is correct.B: This is for changing the bitrate, which is how fast the programmer talks to the chip.

If your chip is being clocked very slowly you'll need to talk slowly to it to let it keep up. It'll be discussed later, for now don't use it.C: The config file tells avrdude about all the different ways it can talk to the programmer. Theres a default configuration file, so lets just use that: don't use this command switch.c: Here is where we specify the programmer type, if you're using an STK500 use stk500, if you're using a DT006 programmer use dt006, etc.D: This disables erasing the chip before programming.

We don't want that so don't use this command switch.P: This is the communication port to use to talk to the programmer. It might be COM1 for serial or LPT1 for parallel or USB for, well, USB.F: This overrides the signature check to make sure the chip you think you're programming is.

The test is strongly recommended as it tests the connection, so don't use this switch.e: This erases the chip, in general we don't use this because we auto-erase the flash before programming.U:r w v::format: OK this one is the important command. Its the one that actually does the programming. The is either flash or eeprom (or hfuse, lfuse or efuse for the chip configuration fuses, but we aren't going to mess with those).

The r w v means you can use r (read) w (write) or v (verify) as the command. The is, well, the file that you want to write to or read from. And :format means theres an optional format flag. We will always be using 'Intel Hex' format, so use i So, for example. If you wanted to write the file test.hex to the flash memory, you would use -U flash:w:test.hex:i. If you wanted to read the eeprom memory into the file 'eedump.hex' you would use -U eeprom:r:eedump.hex:i.n: This means you don't actually write anything, its good if you want to make sure you don't send any other commands that could damage the chip, sort of a 'safety lock'.V: This turns off the auto-verify when writing. We want to verify when we write to flash so don't use this.u: If you want to modify the, use this switch to tell it you really mean it.t: This is a 'terminal' mode where you can type out commands in a row.

Don't use this, it is confusing to beginners.E: This lists some programmer specifications, don't use it.v: This gives you 'verbose' output.in case you want to debug something. If you want you can use it, but in general we won't.q: This is the opposite of the above, makes less output.

In general we won't use it but maybe after a while you wold like to. The ones you'll use 99% of the time are highlighted in red. Let's review them in more detail.

To get a list of supported programmers, type in avrdude -c asdf ( asdf is just some nonsense to get it to spit out the list of programmers) Here is my output, yours may vary a little. Don't bother memorizing it, just glance through the list.

To get a list of parts supported by avrdude, type in avrdude -c avrisp (it doesnt matter if you're not useing an avrisp programmer) without a part number into the command line. Don't memorize this list, just glance over it to get an idea of the chips that are supported.

This switch tells avrdude where to look for your programmer. If you are using a USB connected device, you can just use -P usb or, leave it out. The programmer automatically knows when the programmer is a USB device. If you are using a parallel port or serial port programmer, you should use this option to indicate what port the programmer is connected to. 99% of the time its lpt1 (parallel) or com1 (serial) but you can always check it by looking under the Device Manager. Open the System Properties control panel Click on Device Manager, and open up the Ports submenu.

All of the serial and parallel ports are listed. There may be multiple COM ports but there's usually only one parallel (printer) port. For Mac's, there are no parallel ports. However, if you're using a (which lets you use an STK500 or AVRISP v1 with a Mac) then you'll need to specify the serial port.

I don't know a foolproof way yet but the way I do it is in the Terminal I type in ls -l /dev/cu. and it will spit out a bunch of stuff (I screwed up the screen capture, this image has another window in front of it, but just ignore that) /dev/cu.Bluetooth is the built in bluetooth stuff, dont use that. /dev/cu.modem is the modem (if there is one), dont use that either. What you're looking for is something like /dev/cu.usbserial or /dev/cu.KeySerial1 or something similar. In this case its /dev/cu.usbserial-FTCTYG5U. OK we're at the important part.

This is where we actually get around to telling avrdude how to put the data onto the chip. This command is rather complex, but we'll break it down. can be flash, eeprom, hfuse (high fuse), lfuse (low fuse), or efuse (extended fuse) r w v - can be r (read), w (write), v (verify) - the input (writing or verifying) or output file (reading) :format - optional, the format of the file. You can leave this off for writing, but for reading use i for Intel Hex (the prevailing standard ) For example:.

To write a file called firmware.hex to the flash use the command: -U flash:w:firmware.hex. To verify a file called mydata.eep from the eeprom use the command -U eeprom:v:mydata.eep. To read the low fuse into a file use the command -U lfuse:r:lfusefile.hex:i. OK enough of this jibber-jabber.

Its time to program the firmware into a chip! Get your AVR target board ready to go, we'll be using an attiny2313 in this example but of course you should substitute the chip you're using (in which case the code will probably not do anything). Make sure the device is powered, either by batteries or a wall plug or by the programmer if the programmer can do it. Download the file and place it in C: (Windows) or your home directory (Mac) Figure out what programmer you are using and which port its connected to (in this example I'll be using a but anything is fine.) Since the usbtinyisp is a USB programmer I can leave off the -P switch. Fuse memory is a seperate chunk of flash that is not written to when you update the firmware.

Instead, the 3fuses tend to be set once (altho they can be set as many times as you'd like). The fuses define things like the clock speed, crystal type, whether JTAG is enabled, what the brownout (minimum voltage) level is, etc. First you'll want to calculate fuses using the very convenient To program the fuses, use: avrdude -c usbtiny -p attiny2313 -U lfuse:w::m avrdude -c usbtiny -p attiny2313 -U hfuse:w::m avrdude -c usbtiny -p attiny2313 -U efuse:w::m Where is the desired fuse value, in hex. For example to set the high fuse to 0xDA: avrdude -c usbtiny -p attiny2313 -U hfuse:w:0xDA:m Setting the fuses incorrectly can 'brick' the chip - for example you can disable future programming, or make it so the chip is expecting an external crystal when there isn't one.

For that reason I suggest triple-checking the fuse values. Then check again, make sure you aren't disabling ISP programming or the Reset pin or setting the clock speed to 32kHz.

Then verify again that you have the correct chip for calculation. Then finally you can try writing them to the chip! Remember: once you set the fuses you do not have to set them again. If the programmer is not properly connected to the chip, you'll get the following message: initialization failed, rc=-1 Double check connections and try again, or use -F to override this check Don't use -F to override the check, even though it is suggested! This means that the programmer couldn't talk to the chip. If you are using a 'simple' programmer such as a serial or parallel port bitbang programmer, it could mean the programmer is at fault. Otherwise, it usually means the programmer is OK but it couldnt find the chip.

Check that the chip is powered, plugged into the socket or programmer properly, the programming cables are plugged in correctly, the header is wired correctly, etc. 99% of the time, it is a problem with wiring.

So here you have this long-awaited post. In this article we will see how to program some of the Atmel ATtiny family, particularly those highlighted in the title, using Arduino libraries and Arduino Uno as ISP. Obviously, everything can be done using a dedicated programmer, but here we will not talk about this subject because the differences are minimal. Let’s start with a premise: on the ATtiny we will not upload the bootloader, but we will proceed to load our sketch directly into the memory of the microcontroller. So this is a first difference with the ATmega328.

There are perhaps some ATtiny bootlaoders, but it doesn’t make sense to load them for several reasons. The first is the small memory of this microcontroller (ATtiny85 has 8Kb compared to 32Kb of the Atmega328). Secondly, most of the ATtiny do not have serial hardware, so it would make not sense to install a bootloader if it doesn’t help to do uploads via serial port. Let us now see the advantages of the ATtiny85 compared to Atmega328: 1 – lower power consumption (and therefore suitable for projects with battery) 2 – smaller size (the ATmega328 has 28 pins while the ATtiny85 has only 8 pins) 3 – lower cost Obviously with fewer pins we have a limited number of I/O compared to big brothers.

As regards the programming is very similar to that seen in the and the before that. Let’s see the pinout of ATtiny85 that we will use as starting example in this article: From Arduino point of view: +-/ -+ Ain0 (D 5) PB5 1 8 VCC Ain3 (D 3) PB3 2 7 PB2 (D 2) INT0 Ain1 Ain2 (D 4) PB4 3 6 PB1 (D 1) pwm1 GND 4 5 PB0 (D 0) pwm0 +-+ So if I want to use the PIN6 as a digital output I will use pinMode (1, output) and if I want to read the analog input from PIN3 I will use analogRead (A2). Of course, as in Arduino, we can use analog inputs as digital outputs.

The serial hardware does not exist as we said, but we can use the appropriate PIN2 (PB3) as unidirectional software serial. Practically using the standard Arduino command Serial.begin (9600), on PIN2 we have a TX signal that can connect to RX pin of an USB-SERIAL converter, in order to communicate from the ATtiny to the PC, so it’s like having a “read-only serial”. But let’s get to the point: compared to the programming of the Atmega328, the programming of the ATtiny requires some changes and the adding of some libraries to the IDE. I recommend using the 0023 version of the IDE, which can be downloaded from the website of Arduino (with other versions it was unsuccessful), and create a separate special folder to be used only ATtiny programming. So if we already have Arduino (for example in the c: Arduino folder), we will create a new folder called for example c: Arduino-Tiny.

After this we have to download the core arduino-tiny-0022-0009.zip, from, then we have to download the library PinChangeInterrupt-0001.zip from and finally the library TinyTuner-0003.zip found. The first file needs to be unzipped in hardware folder (eg: c: Arduino-Tiny hardware). It will ask you to overwrite some files. Answer yes without problems.

The other two libraries need to be unpacked under the libraries folder (eg c: Arduino-Tiny libraries). At this point it should be alright.

You can either upload your examples using the following scheme: Basically, it’s like the ATmega328. The pin 10 need to be connected to RESET, and pins 11, 12, 13 to pin MOSI, MISO, SCK (ie in this case 5, 6, 7), and of course the power supply. Remember as always to insert the 22uF capacitor between GND and RESET on Arduino UNO otherwise the board will reset and the upload will not work giving you an sync error!!!

At this point, opening our IDE, and an example sketch, we can select Tools - Boards - ATtiny85 @ 1Mhz, then File - Upload to I / O Board. It will give you an error of type “PAGEL,” but you can safely ignore it. You will then see the message “Done Uploading” that will warn you that everything was successful. As you can see it is very simple. The ATtiny by default have fuse set in a way that the microcontroller uses its internal oscillator at 1MHz. And this is the best option for most projects, but if you need more speed, you can program the ATtiny in such a way that it uses its internal oscillator at 8MHz or by using an external oscillator at 16Mhz (see previous posts).

If we want change our ATtiny speed, for example at 8MHz, we need to set the fuse, doing an upload of a empty bootloader, containing only the settings that interest us. To do this, simply select from Tools - Boards the setting of interest (eg ATtiny85 @ 8MHz), and then Tools - Burn Bootloader — w/Arduino as ISP. At this point you will probably get the following error: avrread: error reading address 0x0000 read operation not supported for memory 'lock' avrdude: failed to read all of lock memory, rc=-2 This error is due to the fact that the is missing the line that concerns the operation memory lock in file c: Arduino-Tiny hardware tools avr etc avrdude.conf the line that concerns the operation memory lock.

So we are going to edit this file and add the following line: read = '0 1 0 1 1 0 0 0 0 0 0 0 0 0 0 0', '0 0 0 0 0 0 0 0 o o o o o o o o'; Under ATtiny85 section, below the line memory “lock” that should look like so after the change: # ATtiny85 has Signature Bytes: 0x1E 0x93 0x08. Memory 'signature' size = 3; read = '0 0 1 1 0 0 0 0 0 0 0 x x x x x', 'x x x x x x a1 a0 o o o o o o o o';; memory 'lock' size = 1; write = '1 0 1 0 1 1 0 0 1 1 1 x x x x x', 'x x x x x x x x 1 1 i i i i i i'; read = '0 1 0 1 1 0 0 0 0 0 0 0 0 0 0 0', '0 0 0 0 0 0 0 0 o o o o o o o o'; minwritedelay = 9000; maxwritedelay = 9000;; Now running the bootloader operation should go. If we want to we can fix also the problem of the message “PAGEL” by adding the following lines: pagel = 0xB3; bs2 = 0xB4; Below the line chiperasedelay = 4500 in the Attiny85 section. In the we saw how to program the Arduino bootloader on a standalone Atmega328, while in another we saw how to upload the sketch to the microcontroller with Arduino bootloader on board.

In this post I want to highlight what I believe is the ultimate goal of the projects prototyped with Arduino: program the ATmega328 without a bootloader, so that our programs can completely override the flash of the microcontroller. But why do we do it?

The main advantages are the immediate execution of our program when the Atmega power on, and more space for our programs in the memory of the microcontroller. The disadvantage is the fact that it is no longer possible to program via simple serial (less than reload the bootloader), but we must use a dedicated programmer (or a ArduinoISP) and the time to upload the sketch is a lot longer. I advise you to use this mode only on finished project, while using the Arduino bootloader when we are debugging our programs (with continuous uploads).

But we come to practice. The programming is implemented in the same way as the previous post, with a slight modification. We need to edit the usual file “boards.txt”, and add the line xxxxxxx.upload.using = arduino: arduinoisp in the configuration of the board that we are interested in programming, where xxxxxxx is the name of the board. In the previous post we saw how to program an Arduino in standalone mode. One of the requirements was that the bootloader was already preloaded. But if we had a virgin Atmega328, or if we wanted to program our micro to be used without an external oscillator, what should we do?

If you already have an AVR programmer, it is very simple, and I will not describe here, partly because not everyone has this accessory. So let’s see how to use our Arduino UNO as ISP programmer. Is said that with the UNO is not possible but in reality with a little trick, you can bypass the problem. Do not be discouraged if there are synchronization problems while uploading the bootloader, for every problem there is a solution but let us see the procedure. First, I highly recommend you use the 0022 version of Arduino IDE. With version 1.0, I was able to upload occasionally and with difficulty. I would therefore advise to keep the two installations of the software installed.

In un folder the 1.0 and in another the 0022. Both can coexist without giving discomfort with each other.

Then open the 0022 IDE to load the sample file sketch “ ArduinoISP“. This example allows you to transform our board in an AVR programmer. Once the file uploaded we can connect our UNO according to the following scheme: We must then connect as shown, pin 10 of the UNO to RESET pin of the Atmega, and pins 11, 12, 13 to pin 17, 18, 19 of the microcontroller (or pin 11, 12, 13 of another Arduino board ). In this scheme is not shown, but before we go further we must connect a 22uF capacitor between GND pin and RESET pin in the Arduino board, otherwise during the upload will take place an autoreset and the IDE will give you a sync error. At this point we can safely select the menu Tools - Board - Arduino Duemilanove or Nano w / ATmega328 and launch Burn Bootloader - w / Arduino as ISP and if everything is done correctly we should have our bootloader loaded on the microcontroller, ready to be programmed via serial as shown in the previous post.

Our Arduino UNO however, could be reprogrammed normally (remember to remove the capacitor previously inserted). Obviously we can not just load the bootloader on an standalone Arduino or on breadboard, but also on another Arduino UNO, 2009, Mini, etc. But what if you wanted to program the board with minimal configuration without external oscillator? The procedure is slightly different because in default IDE Boards there isn’t a configuration of this type.
