When we used DRV8884EVM, We meet some problem need to help. when we set as below picture, we selec the start/stop steps button. we test the Step pin waveform of the DRV8884 chip(the 2rd channel wave), we find that the wave can't change after 32ms, and after 60ms, there is also no any change . when we go on , the wave change. So our quertion is that when the wave would chage after we select the start/stop step button, and is there any rule ? the PPSPS vuale can affect it ? how the ppsps control the PPS ?
