Helllo,

How can I connect an external processor, for the ADS131A04EVM, which can communicate via [ Mosi, Miso, Sclk ] pins ?

I guess we need to short JP1. Do I need to do anything else ?

Hi Anand,

Shorting JP1 would be a start, you still need to apply the SPI control signals to the ADS131A04, which you could do through J3.

Hi Tom,

I compared boards silk and schematics, I found that they do not match about SPI-buss.
Which is correct?

Hi ACGuy,

It looks like MOSI and MISO are swapped in the silkscreen. Thank you for pointing that out to us. We'll get it fixed with the next revision of the PCB.
