ADS1298 Measures problem

Other Parts Discussed in Thread: MSP430F5529

Hi, i have my MSP430F5529 connected to the ADS1298-EVM, i can write and read registers correctly but there is a problem when i try to read the 8 channels conversion results, the first time, values are in the correct order:

First the Status Word "C0 00 00" and then the values for each channel, however at the next conversion i read the values but they are not in order, the Status word is moved 3 posicions down or it has other values than expected...

Any help is welcome, thanks.

  • Ensure that you are waiting until the next DRDY before you read the channels again.  If you keep reading before the next DRDY, the channels repeat with the same data.

    You might also want to make sure that you are capturing the correct about of data.  The status and channel data show up in the same position during every read.  You might also want to check if you are possibly incorrectly storing/saving the data (data pointers to memory?) somewhere.
