comparison projects/basic_blink/render.cpp @ 81:92145ba7aabf

Updated PRU code to allow pinModeFrame() and [untested] digitalWriteFrame() and analogWriteFrame() to be called from setup(). Updated basic_blink example accordingly.

 //
 // Return true on success; returning false halts the program.
 
 bool setup(BeagleRTContext *context, void *userData)
 {
+    pinModeFrame(context, 0, P8_07, OUTPUT);
 	return true;
 }
 
 // render() is called regularly at the highest priority by the audio engine.
 // Input and output are given from the audio hardware and the other

   static int status=GPIO_LOW;
 	for(unsigned int n=0; n<context->digitalFrames; n++){
     if(count==context->digitalSampleRate*interval){ //if enough samples have elapsed
       count=0; //reset the counter
     // status=digitalReadFrame(context, 0, P8_07);
-      if(status==GPIO_LOW) //toggle the status
-        status=GPIO_HIGH;
-      else
-        status=GPIO_LOW;
-      pinModeFrame(context, n, P8_07, OUTPUT);
-      digitalWriteFrame(context, n, P8_07, status); //write the status to the LED
