If you check my code in post #20 you'll see:
read_sonar( TriggerR, SonarR, rangevalueR, arraysizeR);
..........
/**********************************************************/
void read_sonar(int txpin, int rxpin, int* ary, int asiz)
{
Also, must be "&&" in the other, I forgot to fix it in post #20 code. It doesn't matter in regards
the 2nd sonar, 1st sample problem.
