Hi Greg,
For interfacing MCU with ADS131E08 currently we are using 4 SPI lines. We will be using ADS in continuous mode.
Is DRDY signal necessary?
Datasheet says if no data is retrieved from device, DOUT and DRDY behave similarly in this(RDATAC) mode.
Can DOUT be used as DRDY?
For how much time data will be available in the registers?
Can I read data at any time between the 2 DRDY pulses (excluding tupdate time)? With 12MHz SPI clock it will take ~20uS for reading data.
