Re: Problems with Wifi Shield

OK, Here you go: Doesn't work; P1 or P2 do not connect (I've beeped out the connections several times with a multimeter, and wiggled it every way I can imagine) (swapping OpenMV main boards gives the same syptoms, but with other pins): DSC01405_badPin.jpg The WiFi shield works with jumpers (I ran ou...

py_sensor.c code question

I'm confused by this code -I'd submit...
