Hmm, it's probably just a loose/weak connection somewhere..?

It's working on the breadboard now =D

Kind of an odd solution, but dropping the clock rate back down to 8Mhz with xdiv=0x01, same as the nano got results

void nnn_ILI9341::clock_modifier(uint8_t xdiv){
CLKPR = 1<<7;
CLKPR = xdiv & 0x0F;
}

Well, it worked for a bit on the breadboard, loose connections(?) permitting

Still no luck with the harness / display out, though it's reading the touch input over spi just fine

 No.54

Started making a second harness using solid-core jumper-wires, display tested okay on usb power prior to wiring in the touch interface, but now again doesn't want to work

Also with both harnesses display and touch works when the micro is powered directly from a couple of AA batteries, as an anon mentioned elsewhere

 No.56

More tests, 2xAA through a little voltage step-up chip for 5 volts, 32u4 / harness 2
Display is working

Tried to repeat display working without touch connected using jumpers, usb connected / fail?

It really doesn't want to work on the 32u4/pro micro with usb connection for some reason

 No.147

use a scope
