At present, I configure ADC12DJ3200 according to JMODE 0 mode, which can increase SYNC, but I now encounter a dilemma. The signal I receive has nothing to do with the input signal, that is, I have not received the signal from ADC.
And I see TI also provides an ADC12DJ3200 GUI. I also use this GUI to generate a set of register configurations according to JMODE 0. But according to this configuration, I still haven't received the correct data. I don't know what's going on. Please know someone to guide me. Thank you very much.
The hardware has been tested by an oscilloscope. The input signal of ADC is on the pin of the input signal.
In addition, using the Repeated ILA test mode in the test mode, we can see the repetitive ILA of gt0_rxdata~gt7_rxdata.
Using the Ramp test mode test pattern, we can see that every 8 bits of gt0_rxdata~gt7_rxdata increase by 00~ff, such as a set of data 0x65646362, 0x69686766.
But the 12-digit data that is solved according to the data format is not the increasing data of 00-0f. What's the matter?
The following is my SPI register configuration for JMODE 0 generated by GUI:
