<![CDATA[328p firmware workflow]]>Several of your products use a 328p (cardkb, makey, faces) and these chips all have their own firmware. How do you upload the firmware for the 328p on those products. Do you keep the unit connected to the M5Stack or do you have to use an isp to upload it.

Thank you both for your response.

Looks like you need to solder a header onto the board to program them.

If you have one of the Arduino products you can use them as a programmer via a program that is part of the default Arduino libs. For my servo module I use an Arduino 328p-pu which is the dip version and so I can just swap the ATmega chip out of the Arduino board and program it normally from arduino
