TI (BurrBrown) ADS7871 SPI AtoD Converter Code Wanted

[larosta]

I believe that I searched the forums looking for some sample code for using the TI (BurrBrown) ADS7871 SPI AtoD Converter and did not find too much that was relevant.

Before I dive head first into it I thought that I would see if anyone was willing to share any code for:

a) initializing the device.
b) selecting the channel to be read.
c) writing the 14 bit data to a variable for further processing.

Thanks in advance.

I have never used that family - but because all data exchanges for the ADS78xx family are multiples of 8 bits -
it is perfectly suited for the HARDWARE SPI functions of your pic.


My suggestion is to expend some effort, build up a prototype
and begin to program it yourself.

Walk before running:
do something SIMPLE like minimal INIT - and just read ONE port

See how far you get.
Later when you have some work to show, it will be simpler to get others to join in and expand on your efforts.

Here is a link to the evaluation module. You should find code in the zip file.
