ATMEGA324PB

Using Arduino Microcontrollers

Do you plan to add support for this MCU ?
It is very interesting because of its number of I/O pins greater than that of the ATmega328PB, which is supported.
I've patched an IDE 1.8.5 to support it, and it's a light and easy job, just one file to edit and three files to add.

MiniCore has support for the ATmega328PB:

Note there is one extra installation step:

That extra step will no longer be necessary after the next release of Arduino AVR Boards/Arduino IDE.

MightyCore has support for the ATmega324PB!

Note there is one extra installation step though:

I had not seen the ATmega324pb, looks like they copied stuff from the 328pb.

I am sure impressed with those MCUdude cores, I wonder if there is any chance the ATmega4809 could get a core. Perhaps it could be called the HowDoTheseXPeripheralsWorkCore.

Well, since the new "Uno WiFi" is supposed to use the 4809, presumably Arduino is going to implement such a core.
I think it would be very frustrating to try to write any code, only to have the official version end up quite different...
(alas, this applies to the other "new-peripheral" AVRs like the ATtiny817 and ATtiny416 (both of which have "Xplained" development boards available from Microchip, so they're more interesting than other random chips...)

First I have to wait until the UNO Wifi is released with all its documentation (+toolchain +avrdude), to see how they mapped the pinout and implemented peripherals like SPI and i2c. Then I plan to design a simple dev board I can use to test all IO pins (I assume the UNO wifi doesn't break out all pins). I can't guarantee we'll end of with anything, but I'll at least give it a try :slight_smile:
