Problem white screen on my devo 7e was created by Eyolon
Hello !
One month later, i've moded my devo 7e with a 4 in 1 module and deviation 5.0 with success but since many days, i've only a white screen

I've flash and flash again but nothing change. the screen display anything

I guess the SPI works because i've the welcome signal when i turn it on and i've recheck wiring with the screen but everything was not clear : i've clearly found only data/command, clock and CS pin but not mosi or miso ?
and it apear clock have no signal...

There is any way to debug this ???

EDIT : i've use this for my mod : www.deviationtx.com/forum/how-to/5955-7e...he-devo-version-4in1

and this for my research of the problem : pin mcu

thanks for your help and your job. In the small period that worked, i was realy happy to control all of my models !
