HI all.. Trying to implement a Graupner SumD receiver onto a Flip 1.5 board and am seeing an odd issue.. Because I will lack a GUI interface I had planned on using an I2C OLED display for setup and tuning...
problem 1 : when the OLED is connected the serial data stream from the receiver is corrupted (glitching). if the OLED is not "on" the data stream is fine.. can solve this by not flying with the OLED connected but looking for a fix.
problem 2: when using the OLED config routine it "locks up" after entering the "home screen" of the setup.. it is like the data from the serial receiver goes away and you get stranded on the first screen with no way to move or exit.
both issues tested using the same code and a PPM receiver and they don't exist.
both issues also tested on a Mega board with OLED and receiver on serial 1 and both are issues here also.
