Part Number: ADS8681 Dale Li wrote the following post at Feb 12, 2019 5:54 PM:Hi Kanchan, I assume that you are using below connections to your microcontroller(as a master): 1. Using SDI from CN3 connector to your microcontroller's MOSI. 2. Using SDO from CN5 connector to your microcontroller's MISO. 3. You are not using SDO from CN3 and SDI from CN5. If my understanding is correct, these connections are right, but you will have to program the configuration register in each ADC device with identical values The device must operate with single SDO-0 output. Also, bits 7-0 in SDO_CTL_REG register must be programmed to 00h. Thanks. Regards, Dale yes absolutely! the connection are right..i could configure only one of the device couldnt make same the same configurartions for second device..i dont understand where am i mistaking. see as per datasheet the configuration should be done with 32 bit reg and clock so if i need to make it for 2 devices i just need to repeat the same instruction of configuring registers for the two time? right? i have done the same procedure..but i could read the output of the second device only not the first device..that i identified from the inputs provided. . tell me what is the role of reset bar...i have tied both the reset bar to VCC.
