DIO with AdcPro

Other Parts Discussed in Thread: ADS1278EVM-PDK, ADCPRO

I have ADS1278EVM-PDK and would like to know if and how to do digital input with adcpro preferably without first saving to a file.

Since the kit already contains mmb0 with a dsp I thought the basics for that were already in place.

Can you advise ?

Alex,

Can you explain more precisely what you mean?

I have a sensor where its microcontroller already outputs the value in a byte format.

I would need to connect these 8 bits to the MMB0, and setup AdcPro to read and display this 8 bit value.

Is that possible and where can I find detailed info for MMB0 ?

Alex,

There are no digital I/O pins made available for the MMB0 that are not already in use as part of our modular evaluation platform footprint. The MMB0 is not intended to be a full embedded development tool, it is an evaluation platform. There are a few GPIO pins specified in our footprint, but not enough for you to connect to aforementioned sensor. In the case of the ADS1278EVM-PDK these GPIO lines are in use for the EVM-PDK so they are not open for you to modify and retain full EVM-PDK functionality.

Outside of header J4 no other digital signals are made available from the MMB0, with the exception of J8 but that is reserved for a ICDI/emulator.

Thanks, that answers my question, I was afraid that might be the case.

BTW, EVM user guide says about MMB0 "For schematic and other info contact TI.

Can you provide that for me, thanks.

Alex,

MMB0 Schematic attached. Please note that the MMB0 schematics are unsupported, meaning there is no additional documentation to be provided to explain this schematic or functionality of the MMB0. Enjoy!
