NesC (variant of C): implicit declaration of function startTimers() - nesc

Question

I am compiling the following code (on a mote). And I have the following error:
line 174: implicit declaration of function 'startTimers'
Could you please help me?
Here is my code.

#include "Oscilloscope.h"

notion of time). */

Many thanks in advance for your help !

Answer 1

The function startTimers is called in RadioControl.startDone before it is declared and defined. Just move the definition of startTimers higher, before it is used in the code.
