So I have a simple program, as soon as a GPIO goes high it fires an interrupt which reloads a counter, when the GPIO goes low again it firest another interrupt which reads the counter.
I have checked using a logic analyser that the interrupts are firing correctly but for some reason the counter value never changes, I am feeding it an 11ms signal and a 1MHZ clock so I am expecting the counter to read 65535-11000 = 54535 but it is reading zero. Help
Bundle is attached
I was stopping the timer originally before I went the reload way, oh I like your method with it all in hardware.
So when the capture interrupt fires do I read the counter and do nothing else as the hardware will reload it and whatnot? This is what I was trying to do at first have it all in hardware but I couldnt understand the TCPWM documentation
