Hi Jehan, If you are tying CS low, then part of the problem is the command needs to timeout as you are not sending enough SCLKs for the command sent. Your command is to read registers starting at register 1, reading 10 registers (as the second byte is the number of registers to be read minus 1). Also, many of your digital lines go through resistors or connect to resistors as pullups or pulldowns. I would suggest making sure that all supplies are available at the device pins of the ADS114S06 , and reset is pulled high. The device will not communicate if any supplies are missing or if the RESET pin is floating or held low. Another method for checking if the ADS114S06 is truly in an operating state is to pull the START/SYNC pin high and monitor DRDY. DRDY should be pulsing at the default data rate. If you do not see this, then the ADS114S06 is not powered or is in a reset condition. Best regards, Bob B
