Atmel AVR

Configuration:platform = atmelavr

Atmel AVR 8-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 industry’s 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 programming

PlatformIO has a built-in target named fuses for setting fuse bits. The default fuse bits are predefined in board manifest file in fuses section. For example, fuses section for Arduino Uno board. To set fuse bits you need to use target fuses with platformio run --target command.

Custom fuses

Custom fuse values and upload flags (based on upload protocol) should be specified in “platformio.ini” (Project Configuration File). lfuse and hfuse bits are mandatory, efuse is optional and not supported by all targets. An example of setting custom fuses for uno board:

[env:custom_fuses]
platform = atmelavr
framework = arduino
board = uno
upload_protocol = stk500v1
upload_speed = 19200
board_fuses.lfuse = 0xAA
board_fuses.hfuse = 0xBB
board_fuses.efuse = 0xCC
upload_flags =
    -PCOM15
    -b$UPLOAD_SPEED
    -e

MiniCore, MegaCore and MightyCore

MiniCore, MegaCore and MightyCore support dynamic fuses generation. Generated values are based on the next parameters:

Parameter Description Default value
f_cpu Specifies the clock frequencies in Hz. Used to determine what oscillator option to choose. A capital L has to be added to the end of the frequency number. 16000000L
oscillator Specifies which oscillator is used internal or external. Internal oscillator only works with f_cpu values 8000000L and 1000000L external
uart Specifies the hardware UART port used for serial upload. can be uart0, uart1, uart2 or uart3 depending on the target. Use no_bootloader if you’re not using a bootloader for serial upload. uart0
bod Specifies the hardware brown-out detection. Use disabled to disable brown-out detection. 2.7v
eesave Specifies if the EEPROM memory should be retained when uploading using a programmer. Use no to disable yes

Valid BOD values:

ATmega8, ATmega8535/16/32, ATmega64/128 AT90CAN32/64/128 Other targets
4.0v 4.1v 4.3v
2.7v 4.0v 2.7v
disabled 3.9v 1.8v
  3.8v disabled
  2.7v  
  2.6v  
  2.5v  
  disabled  

Hardware configuration example:

[env:custom_fuses]
platform = atmelavr
framework = arduino
board = ATmega32

board_build.f_cpu = 1000000L
board_hardware.uart = uart0
board_hardware.oscillator = internal
board_hardware.bod = 2.7v
board_hardware.eesave = no

upload_protocol = usbasp
upload_flags =
  -Pusb

Bootloader programming

PlatformIO has a built-in target named bootloader for flashing bootloaders. The default bootloader image and corresponding fuse bits are predefined in board manifest file in bootloader section, for example, Arduino Uno. To upload bootloader image you need to use target bootloader with platformio run --target command.

Custom bootloader

Custom bootloader and corresponding fuses should be specified in “platformio.ini” (Project Configuration File). If lock_bits and unlock_bits are not set then the default values 0x0F and 0x3F are used accordingly. An example of setting custom bootloader for uno board:

[env:uno]
platform = atmelavr
framework = arduino
board = uno

board_bootloader.file = /path/to/custom/bootloader.hex
board_bootloader.lfuse = 0xFF
board_bootloader.hfuse = 0xDE
board_bootloader.efuse = 0xFD
board_bootloader.lock_bits = 0x0F
board_bootloader.unlock_bits = 0x3F

MiniCore, MegaCore and MightyCore have a wide variety of precompiled bootloaders. Bootloader binary is dynamically selected according to the hardware parameters: f_cpu, oscillator, upload_speed:

Frequency Oscillator Upload Speed
20000000L external 115200
18432000L external 115200
16000000L external 115200
14745600L external 115200
12000000L external 57600
11059200L external 115200
8000000L external/internal 57600/38400
7372800L external 115200
3686400L external 115200
1843200L external 115200
1000000L external/internal 9600
