For the record, these are my notes, not a guide for you :-) - -## Known issues: -Anything over 28k will begin to overwrite the boot loader, which is a pain! - -Be sure to check file size with: -``` -avr-size meira_promicro_grahampheath.hex -``` - -## Sounds -I've added a [8ohm 0.5W speaker](http://a.co/6MIKZSy), its a bit large, but it fits in approximately the same space as the ProMicro. I soldered directly to PC6 and GND. - -As the Meira code stood, adding sound increased the hex beyond what the boot loader could handle, so I had to dial way back on features that I wasnt using, like backlighting and RGB support. I also removed function keys, though I think you could restore some of these features, you certainly can't restore all of them and still fit with a boot loader. - -## Build - -Built for the ProMicro with: -``` -make meira/promicro:grahampheath -``` - -Build and upload with, which is cool because it will sense your port. -``` -make meira/promicro:grahampheath:avrdude -``` - -Program a hex directly with: -``` -avrdude -p atmega32u4 -P /dev/tty.usbmodem14111 -c avr109 -v -e -D -U flash:w:meira_promicro_grahampheath.hex -``` - -If you use an AVRISP you will be program a hex without a boot loader: -``` -avrdude -p atmega32u4 -P /dev/tty.usbmodem14111 -c avrisp -v -e -U flash:w:meira_promicro_grahampheath.hex -``` - -## Bricked -Did you overwrite your boot loader? - -I did... - -I used an [Ardunio as an ISP](https://learn.sparkfun.com/tutorials/installing-an-arduino-bootloader), and was able to program various boot loaders.
