Hello,
with an TMS570LS1227 i try to measure wheelspeeds with the help of the ecap pins.
So at the moment i generate a fictiv pwm signal and read the signals. I then calculate 1000000000 / pwm_period to get the frequency.
For higher frequencies this works very well, but when the frequency get very low it produce only ***. So for 400Hz it has a higher value than for 500 and 600Hz has a lower value.
So my question is if anyone knows an easy solution to help me with that problem.
Cheers
Moritz
