Need help with dspic33FJ64MC802

[gabloo]

Hey guys, I hope i post my question in right place. I am a college student and barely have any knowledge about using mplab and microchip but I do have C++ coding experience. My instructor is asking me to build a project using one of the micro chip and we decided to create soil moisture censor using dspic33f. What i don't understand how do i define output and input of chip. All i wanted to do is, when we get sudden voltage out of sensor, i want to run my motor. Before, i wrote actual code, i wrote follow very simple code.

All i wanted to do is make my led shine out of B15 pin. What am i doing it wrong?


#include "p33Fxxxx.h"
int main(void)
{
while (1)
{
_ODCB15 = 1;
_TRISB15= 0;
_LATB15 = 1; }
return 0; }


Thanks in advance,
KoKo

I figured it out about LED part but I am stuck at putting voltage input into my chip.

What i m trying to do is, if chip pick up sudden voltage from sensor, it will turn on the led. How kind of coding do i need so that chip will read voltage input and convert it to digital.


Thanks
