Posted on April 28, 2009 at 15:14Hi guys.
I'm using a ST10F269Q2 and I'm trying to use GPT2 T5 and T6 in the capture/reload mode (page 184 in the user manual) to generate interrupts 4 times faster than they come into my system. I can't however get the generated interrupts in phase with the incoming interrupts. The phase continues to drift. Am I doing something wrong or is there no way to get the two in phase?
My init code is as follows:
T5CON = 0x1005;
T5R = 1;
T5SC = 1;
T5CLR = 1;
T6CON = 0x0003;
T6R = 1;
T6SR = 1;
T6UD = 1;
T6OE = 1;
DP3_1 = 1;
P3_1 = 1;
CAPREL = 0x0000;
Thanks Neil.
