Hello Albertas, Thank you for your post and welcome to our forum! Could you provide more details about the bogus data that you are reading? How are the analog inputs configured and how do you know the data is invalid? When using the auto-increment feature, you only need to specify the R/W bit and the starting address in the command field, followed by enough SCLKs to read from all the registers that you require. /CS can remain low through the register read. Keep in mind that the entire SPI operation must be completed before the next /DRDY (which appears to be driven by ECG_CH3 at 1.067 kSPS in your setup). Can you tell us what your SCLK frequency is? Also, it might help if you could share a capture of your SPI transaction with /DRDY, SCLK, /CS, and DOUT. Best Regards,
↧
