I'm trying to use an ADS1278-EVM evaluation board to interface with a National Instruments NI-8452 SPI module to communicate directly with the ADS1278 and bypass the MMBO motherboard. Ideally I would like to make a proof of concept prototype out of the evaluation board first before I design my own board for the ADS1278.
Does anyone have any experience doing this? I'm trying to determine the correct setup for the switches and jumpers on the eval board to use an external SPI communication. My hope was to simply use the motherboard to generate the necessary supply voltages for the ADC and provide it with a clock signal. Does the motherboard automatically provide a clock signal for the ADC even when I am not using the ADC Pro software? The only SPI wires I am using for communication to a PC are the SCLK, DOUT, and DIN. My biggest concern is that the ADC is not receiving a clock signal from the motherboard (should be 27MHz).
Is it possible to do this from the eval board without having to design my own board for prototyping this communication system?
Thanks
