Other Parts Discussed in Thread: ADS124S08
Hello sir,
I have tried logging the data of ADS124S08 EVM to SD card using arduino, but data is not logging to a file which is present in SD card. I have attached my code here. I am using voltage source (6V) as a input to EVM. But I am able to get the data from EVM using arduino but logging is not happening.
Thanks
Regards
