ADS131m08 interface with microntroller

Hi Sandeep Maurya,

Effectively all of your questions are answered by the ADS131M08 datasheet. I would strongly encourage you to read that document in detail, otherwise you will have a lot of difficulty getting the device up and running in your system

if we are using a separate controller like STM32 or any other do we need to give digital clkin signal if yes what is the frequency.

if we are taking GPIO interrupt based on DRDY pin then what should be the nature of the interrupt by nature I means to say that whether the pin should be initial high and interrupt is on falling or rising edge.

See DRDY pin section (8.5.1.5)

how to read the data like for each channel we need to send the dummy data like 0x00 to send to recieve the data in the next frame.

See SPI communication frames section (8.5.1.7) and ADC conversion data section (8.5.1.9)

Any particular timing if required.

See the Timing and Switching sections (6.6 and 6.7)

Again, please read the datasheet. We can answer your questions, but this will not help you understand how the ADC works. Reading the datasheet will
