I’m working on a ControlChain device, using the Arduino Mega 2560 as a basis (more pins, memory, etc).
I have a small 1.8" TFT display from Adafruit. I’ve written some basic code to display some stuff on the display, haven’t yet started incorporating the CC stuff.
I find when I have the CC shield attached, and power it via the CC port, rather than USB, the arduino doesn’t seem to want to boot - the first line of my setup function sets the PWM to control the backlight of the display, and it is not even running that so it seems to me like setup() isn’t even called. The device is daisy chained off my MOD Footswitch. It’s not running out of current is it?
