Hi,
My client encountered problems with the ads131a02: The initialization process is normal, but the adc data obtained is 0, and the raw data received via spi is 0x2200000000000000000.
The synchronous slave mode is used, and the spi rate is 1.3MHZ. Hardware wiring: IOVDD and AVDD are connected to 3.3V power supply respectively, cs and DRDY are connected together, and gpio is set to HIGH after RESET is powered on.
The problem is basically the same as the following link:
How was this problem resolved? Because this link is no longer open.
