Forum Post: RE: ADS1241 Registers

Hi Hamid,

If you look at the datasheet within the section towards the end you will see that the write values are don't care once the command has been issued.  A couple of things to consider.  To verify the read is working why are you trying to read from the DOR registers?  Try reading from registers that won't change values from the default settings, such as the first several registers. 

If you are going to read data, it is much easier to issue the RDATA command which is one byte instead of two for the command.  Once the command has been issued, you must wait the 10+ us before sending any more clocks.  In your scope shot you are sending the RREG command to start reading at register 0x0D for 3 registers.  This information is two bytes.  After the two byte command you must wait the 10us before you do anything more.  Your 10us delay is after byte 3 which is incorrect.

If using the RDATA command, this is a one byte command so you would delay after the first byte.

Best regards,

Bob B
