  1. Hi, So I simply wanted to try out my new CC3220SF using Energia. Unfortunately I noticed that I always get the wrong readings from the pin. I used a voltage divider to ensure the voltage connected to the analog pin is no more than 1.3V. For that I simply took three 1k Ohm resistors and put them in series then connect a parallel circuit from the last resistor to the potentiometer. I also have ensure that the jumper powering the opAmp to enable the ADC on board is populated. I simply used the example code then changed the pin number. I also already have tested changing all the pin number but it all comes down to nothing. But to simplify your work to help me, here's the code nonetheless, void setup() { // initialize serial communication at 9600 bits per second: Serial.begin(9600); // msp430g2231 must use 4800 } // the loop routine runs over and over again forever: void loop() { // read the input on analog pin A3: int sensorValue = analogRead(A0); //I tried A0,A1,A2,A3 already // print out the value you read: Serial.println(sensorValue); delay(1); // delay in between reads for stability } And here is my setup: LaunchPad board name and version: CC3220S_LAUNCHXL (Rev-A) Energia IDE version: 1.8.11E23 Board package version: 5.6.2 OS name and version: Windows 10 Thanks, Razi Hashim
  2. 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
