Hei!
I am a new user for f28335. I want to use the demo c2812speedcontrolDC to measure the speed of PMDC, but , i use the f28335. I changed the c281xPWM block to c280xPWM , C281xQEP block to C280xeQEP block, and processor F2812 eZdsp to F28335 eZdsp. I have the PMDC motor with encoder, the encoder have A,B signals and index. From theF28335 datasheet, i find the inputs for eQEP module, EQEP2A_ECAP1,EQEP2B_ECAP2. I connect the encoder output A , B to the EQEP2A_ECAP1,EQEP2B_ECAP2, why the EQEP block doesn't work. The EPWM Block can work , motor can work ,encoder also can generate the A,B signals. Is there anything wrong i the EQEP block, because the QEP block i F2812 is different from the EQEP block in F28335. How can I change the EQEP block to get A,B signals from encoder .
