I have problem with ADC ADS8328IPWR.
The problem is show up then I am reading the CFR register and data,
so as to interpret correctly the CFR and data I need to perform bit shift down .
Thus I am losing MSB in data.
Hi Oleg,
If you are missing the MSB, chance are you are violating one of the timing specs, like perhaps the tSU(CSF-SDOVALID). Getting some screen captures of your CFR write and read sequence would be really helpful here in trying to determine what might be going wrong.
Hi Tom.
I send screen capture ,following signals CS, SDI ,SDO of interface SPI .
I hope that help to understanding the problem.
Best regards
Oleg
Hi Tom.
To follow the your of advice , I speed up SCLK up to 20Mhz and sent an extra 8 clocks by writing 0x00 in SPI transmiter , also wrote the reset command and have read back the CFR .
But unfortunately I don't get any of change.
Best regards
Oleg
