Hi Dale, OK, here are some scope plots. My control software is sending 3 commands, one after each other in this sequence (with a 1 second delay in between each one). AdcData1 = Ads8638TxRx(ADS8368_SELECT_CHANNEL_1); // 0x810 AdcData3 = Ads8638TxRx(ADS8368_SELECT_CHANNEL_3); // 0x830 AdcData4 = Ads8638TxRx(ADS8368_SELECT_CHANNEL_4); // 0x840 You can see in the scope plots below, the read data for one channel is interleaved with the write data for another channel.
