Hello,
I am interfacing ADC12138 with STM32. I am trying to read the conversion result from channel 7 with single ended configuration, the reference voltage used is 2.5V and supply voltage is 5V. My SPI settings are - CPOL - low, CPHA - rising edge with clock frequency - 4MHz, MSB first and length 8 bit.
When I do auto cal(0x08), I get read status as 0 on sending read status on next cycle(0x0C) for two times. what could be wrong in the configuration or overall sequence? Also I send 12bit conv (0xF0 for ch 7), I do not get the desired reading.
