Hi, so I have an ATMega 328PB that has an external 8Mhz oscillator. But I want to configure it using the prescaler so I can run it at 4Mhz so I can run the microprocessor at lower voltages such at 1.8v
Does anyone know how I do this? Can it be done via the platformio.ini file or does it need to be done in the actual sketch code?
This is what I currently have in my
[env] platform = atmelavr board = ATmega328PB framework = arduino board_hardware.oscillator = External ; Oscillator type board_build.f_cpu = 8000000L board_hardware.bod = disabled ; Set brown-out detection board_hardware.eesave = yes ; Preserve EEPROM when uploading using programmer build_unflags = -flto board_hardware.uart = uart0 ; Set UART to use for serial upload board_upload.speed = 57600 monitor_speed = 115200 upload_flags = -P$UPLOAD_PORT
