Part Number: DRV8323
Tool/software:
I was wondering if you could help me out with a part of the DRV8323S, the SPI communication. 1977 and 1971, are the adc reads of an amplifier output when CAL is high before and after the unidirectional/bidirectional bit is flipped meaning that ideal it should display 2048 (1.65V) and 4096 after (3.3V)
What's happening instead is that the bits aren't written to at all as VREF (1.65V) does not change to 3.3V and whenever I send a read instruction, what I receive is the command I sent before the most recent one.
