We captured two waveform today. See attachment. There is noise at cursor a and I can see adcBusy0 is high
for 2.88us. That seems like the right conversion time. But it's definitely not the data I wanted. I don't know what pulse width of the CONV x will trigger conversion? May we put small cap to help?
From the second waveform, we can see the noise at cursor b. and busy signal goes low until we reset it(FPGA will check the low and reset ADC. There is nothing on RST because the probe fell off).
Thank you for your help and look forward to hearing from you!
