Hello Group,


While I am new to this group, I have been designing hardware and developing software since I had hair and it wasn't grey. I am trying to use the CC3200 LaunchPad for a simple IoT demo, but I am having a lot of trouble finding the pin assignments; pinMode(RED_LED, OUTPUT), So I came here for help. It must be easy to find since so many people are using Energia and doing things with the CC3200, I'm probably missing something simple.

Hello @@Pauliet and welcome to 43oh...


The pin maps are at energia.nu.  For example, the pin map for the CC3200 is here:  http://energia.nu/pin-maps/guide_cc3200launchpad/


The red LED is at pin number 29.


Or you can look in pins_energia.h for your processor / variant.  For the CC3200 it is listed like so:


static const uint8_t RED_LED = 29;
static const uint8_t GREEN_LED = 10;
static const uint8_t YELLOW_LED = 9;
static const uint8_t PUSH1 = 3;
static const uint8_t PUSH2 = 11;

static const uint8_t A0 = 23;
static const uint8_t A1 = 2;
static const uint8_t A2 = 6;
static const uint8_t A3 = 24;

Or you could write a little sketch and just print it out....

void setup(){
  Serial.print("RED_LED = ");

void loop(){

Note that you may find sketches that use pin nomenclature like P1.0 coded as P1_0.  This has is being deprecated so use the pin numbers or assigned variable names instead in Energia.
