ADS125H01 cannot read and write registers whose addresses exceed 10H, even if CS2(low active) has been pulled down.
Figure 1 below is the write register function (WREG Command), and Figure 2 is the SPI read-write array for single-step debugging.
The written data is 55 53 65 00, the theoretically received data is FF 55 53 65, but the actually received data is FF 00 00 00, indicating that the write failed.
Similar problems occurs in read register data Command.
How to configure the SPI initialization with MCU STM32G474? NSS is connected to CS1 and CS2 is connected to another GPIO. When the NSS is software triggered, the SPI receives 7F or FF no matter what I write/read. When the NSS is hardware triggered (input or output), CS1 is always low and I cannot read and write registers whose addresses exceed 10H.
Finally, I used the GPIO monitored SPI, and all the registers can be read/written. Besides, the SPI time sequence description might be SPI mode 0, i.e. (CPOL = 0 and CPHA = 0). In CubeMX, CPHA should be 2edge instead of 1edge.
