ADS1299 and STM32 interface issue

Part Number: ADS1299

Hello guys,

I am working on the interfacing of ADS1299 and STM32.

The issue is that when I try to obtain the Device ID it communicates fine And the SPI communication is working properly but the data ready pin toggles for first adter I start the conversion10 ms and then stops and I could not take the readings of the ADC values after 10 ms.

Hi John,

To help us debug further, you will need to provide more information like the register configuration settings, detailed SPI signals, START and DRDY timing waveforms from oscilloscope and any other relevant information.
