Hi Cynthia, Thank you for the reply. When I try to change the range, I am not seeing it change at all. It is working with default setting only, which is -12.288V to +12.288V. I am using 5VDC input to ADC for testing purpose. I understand that bit banging has some issues. I will change it later when the driver is integrated with our final product code. For now, I am using bit banging in a hope to resolve the issue. I have attached screenshot of waveforms of clock with MOSI signal. I have ensured that the timings are being followed with sufficient allowance. Some more doubts I have are 1. Is my command word correct? I am using 0xD0140002 2. I assume that bit will be latched in ADC on rising edge of clock. Is it correct? 3. Can I change range anytime after power on? 4. Is there any particular command sequence to be followed? or I can simply send 32bit command word and continue to read conversion results as usual? Please look into issue and do reply to me. I need to resolve this issue. Thank you.
