ADS1256: ADS1256 Design Verification

Part Number: ADS1256

Hello guys,

In my project i am using ADS1256 with RPI , i can able to read the adc values with ADS1256 development board with RPI CM4 but i couldn't read the adc values with custom board which is designed from our team. it shows me ID read failed. i have used the source code which is provided from the Waveshare, in the code ID used is 3 but when i run the code iID printed as 15 and ID read is failed. the hardware design and all is done with  the reference of :   https://www.waveshare.com/w/upload/2/29/High-Precision-AD-DA-board.pdf   .

so please help me to resolve this problem.

regards,

sagar m 

Hi Sagar,

What are the differences between your board and the board that worked? If the firmware worked on one board it is likely that there is a hardware issue.

hello bryan,

thanks for your reply actually in ADS1256 kit i have used waveshare source code itself  but it worked for on board potentiometer and LDR with chip select pin what they mentioned and i changed CS,RESET and DRDY pin number to other RPI gpio pins then it showed me ID read failed .

i don't know what to do any hints to resolve this issue??.
