  1. I'm getting very frustrated with this CC3200MOD, and the CC3200 in general. First it started with the A0 analog channel always reading 4096 but now on to some GPIO problems. This should be fairly straight forward but apparently they make everything difficult, so I don't know what to say. I have made a custom PCB for using the CC3200MOD. Its supposed to read the 4 ADCs, 3 for accelerometer, which is working great, 1 for an analog microphone, which isn't working at all, but I've given up on it and going to just mux with one of the 3 working ones. Now I have 3 LEDs on the board for general LED applications. These LEDs are on pins(pins of the MOD device) 6,7,8, which correspond to (according to PinMux Tool) GPIO 15,16,17. So ideally I should be able to just pinMode the pins to OUTPUT, and set them HIGH to have the LEDs working. I should mention right now that I have two populated boards both have issues in the same way. So if I was to do this in Energia it would just be: pinMode(15,OUTPUT); pinMode(16,OUTPUT); pinMode(17,OUTPUT); digitalWrite(15,HIGH); digitalWrite(16,HIGH); digitalWrite(17,HIGH); So this is where it gets strange, only 1 LED turns on, only GPIO16. But here is the kicker, GPIO16 turns on only when I enable GPIO15!! What the heck is going on, I think there is an issue with Energia incorrectly labelling pins but I cannot find the solution. I think this is also the issue with the analog pin, but I want to sort this out first. Does anyone know what is going on? Ill break it down: GPIO16 turns on when I digitalWrite(15,HIGH) GPIO15 and GPIO17 don't turn on at all and get some weird low voltage on them. Using Energia
