Build

$ git clone https://github.com/LexxPluss/chargingboard.git
$ cd chargingboard
$ arduino-cli compile --fqbn MightyCore:avr:1284:pinout=standard,variant=modelNonP,BOD=2v7,LTO=Os,clock=16MHz_external

Program

Program bootloader

Connect Arduino UNO and Charging Board with the following connection and write.

Name	UNO pin	ATmega1284p pin	J4 pin
RESET	10	9	5
MOSI	11	6	4
MISO	12	7	1
SCK	13	8	3
VCC	5V	10, 30	2
GND	GND	11, 31	6

$ arduino-cli burn-bootloader -p /dev/cu.usbxxxx -P arduinoasisp --fqbn MightyCore:avr:1284:pinout=standard,variant=modelNonP,BOD=2v7,LTO=Os,clock=16MHz_external

The serial port specified by -p is the serial port of the Arduino UNO.

Program sketch

If Bootloader is written, Sketch can be written in the following.

$ arduino-cli upload -p /dev/cu.usbserial-xxxxxx --fqbn MightyCore:avr:1284:pinout=standard,variant=modelNonP,BOD=2v7,LTO=Os,clock=16MHz_external

The serial port specified by -p is the serial port of the Charing Board.

Use avrdude to write HEX files.
