Sounds like we are using some of the same hardware, I have AQ32v1 with gps, and the Max7456 breakout I have the basic firmware loaded onto the board and have connected to my PC and all the sensors and GPS loc seem to be working fine, i haven't hooked up any ESCs or servos or anything else yet, and I haven't fed video through the MaxBoard yet!.. lulz.
My actual question to you:
Was Dronin GCS able to update the font of the Max7456 through the AQ32 board? or perhaps yourMax was previously integrated during its Aeroquad life and was updated then?...
I never got all my FPV junk into my AQ hex before it was shelved so many moons ago and i believe the board has some Chinese or Korean font from its manufacture... i remember buying it from the Aeroquad store in like 2012 and there were long discussions in the forums regarding updating the font of this OSD. I think i can use an arduino i have laying around here somewhere if i get desperate. Thanks for any advice, I hope we get our AQs airborne. Flyin high in KS.
