is it possible to make it work on 3.3V 8MHz Atmega32u4? could we get a .hex in the folder? :)
I managed to get it to work by compiling with MPLAB X. I'm able to get the UART to work but not the USB CDC, maybe 8MHz is not fast enough...
by the way, I try to do forget on a constant but it does not work. I get forget bit5 forget ?
Check the PLLCSR register description.
Did you compile FORGET ?
I uploaded 8 MHz hex files. I could not test, and I hope they work.
I can confirm that 32u4-16MHz-UART38400.hex and 32u4-8MHz-USB are working on my board.
I'm flashing using this command : avrdude -p m32u4 -c avrisp2 -e -U flash:w:32u4-8MHz-USB.hex:i -U efuse:w:0xff:m -U hfuse:w:0xdf:m -U lfuse:w:0xff:m
It can be used for Sparkfun pro micro : https://www.sparkfun.com/products/12587 but I'm using it right now on a linkit smart duo 7688
thanks!
