Hi,
I am having great difficulty trying to get my shaft encoder to work using
both sencdr3.icb or fencdr3.icb driver. I am using the QRB1114 optical sensor
connected to analog port 3 with a current limiting resistor of 330 ohms for
the emmiter and the default 47k pull-up resistor from the Handy board. I've
even tried using a smaller valued limiting resistor of 220 ohms and its still
didn't work ! I' ve loaded the sencdr3.icb into the handy board and wrote
this little simple test code to see if my encoder work and so far I have no
result, all I got was a 1. I'd appreciated if some one can help me out on
this one, Thanks in advance.
int encoder_test()
{
while(1)
{
int count;
count = encoder3_counts;
printf("Count: %d," count);
}
return count;
}
void main()
{
while(1)
{
encoder_test();
}
}
