Hello,
I am doing some experiments on the eCap module, but found some bugs
First, two sets of ePWM(ePWM2A, ePWM2B) with a frequency of 150kHz and a phase difference of 180 degrees have been set
After that, set two sets of eCap (eCap1, eCap2 on GPIO24, 25) to detect their pulse signals on the rising edge (ePWM)
The number of counts between CAP1 and CAP2 of eCap1 is 1000 (150MHz/150kHz), and so on
But ECap2Regs.CAP1 - ECap1Regs.CAP1 result is equal to 384 (which is the same as CAP2, 3 and 4)
Theoretically, because the counter frequency of eCap is 150MHz, and 150M/150k=1000
The calculation results (ECap2Regs.CAP1-ECap1Regs.CAP1) with a phase difference of 180 degrees should be 500, right?
Can anyone solve this problem or encounter the same problem but solve it later?
Best regard
Ray
