Atmel AVR

Configuration:platform = atmelavr

Atmel AVR 8- and 32-bit MCUs deliver a unique combination of performance, power efficiency and design flexibility. Optimized to speed time to market-and easily adapt to new ones-they are based on the industrys most code-efficient architecture for C and assembly programming.

For more detailed information please visit vendor site.

Configuration

Upload using Programmer

To upload firmware using programmer you need to use program target instead of upload for platformio run --target command. For example, platformio run -t program.

Warning

Upload options like upload_port don’t work as expected with platformio run -t program. You need to use upload_flags if you want to specify custom port or speed (see examples below).

Note

List of avrdude supported programmers are accessible with avrdude -c ?

Configuration for the programmers:

• AVR ISP

  [env:myenv]
  platform = atmelavr
  framework = arduino
  upload_protocol = stk500v1
  ; each flag in a new line
  upload_flags =
      -P$UPLOAD_PORT
  
  ; edit this line with valid upload port
  upload_port = SERIAL_PORT_HERE
  

• AVRISP mkII

  [env:myenv]
  platform = atmelavr
  framework = arduino
  upload_protocol = stk500v2
  ; each flag in a new line
  upload_flags =
      -Pusb
  

• USBtinyISP

  [env:myenv]
  platform = atmelavr
  framework = arduino
  upload_protocol = usbtiny
  

• ArduinoISP

  [env:myenv]
  platform = atmelavr
  framework = arduino
  upload_protocol = arduinoisp
  

• USBasp

  [env:myenv]
  platform = atmelavr
  framework = arduino
  upload_protocol = usbasp
  ; each flag in a new line
  upload_flags =
      -Pusb
  

• Parallel Programmer

  [env:myenv]
  platform = atmelavr
  framework = arduino
  upload_protocol = dapa
  ; each flag in a new line
  upload_flags =
      -F
  

• Arduino as ISP

  [env:myenv]
  platform = atmelavr
  framework = arduino
  upload_protocol = stk500v1
  ; each flag in a new line
  upload_flags =
      -P$UPLOAD_PORT
      -b$UPLOAD_SPEED
  
  ; edit these lines
  upload_port = SERIAL_PORT_HERE
  upload_speed = 19200
  

• Bus Pirate as ISP

  [env:myenv]
  platform = atmelavr
  framework = arduino
  upload_protocol = buspirate
  ; each flag in a new line
  upload_flags =
      -P$UPLOAD_PORT
      -b$UPLOAD_SPEED
  
  ; edit these lines
  upload_port = SERIAL_PORT_HERE
  upload_speed = 115200
  

Upload EEPROM data

To upload EEPROM data (from EEMEM directive) you need to use uploadeep target instead upload for platformio run --target command. For example, platformio run -t uploadeep.

Fuses

PlatformIO has built-in target named fuses for setting fuse bits. The default fuse bits are predefined in board manifest file in fuses section. For example, Arduino Uno Fuses.

To set fuse bits you need to use target fuses for platformio run --target command.

Custom Fuses

You can specify custom fuse bits. Please create custom extra_scripts and override default “fuses” command:

platformio.ini:

[env:custom_fuses]
platform = atmelavr
extra_scripts = extra_script.py

extra_script.py:

Import('env')
env.Replace(FUSESCMD="avrdude $UPLOADERFLAGS -e -Ulock:w:0x3F:m -Uhfuse:w:0xDE:m -Uefuse:w:0x05:m -Ulfuse:w:0xFF:m")
