Using SPI pins
-
Hi,
is it possible to use digital pins used by Unipi board as digital outputs (for other purposes)?
To be precise I have an SPI sensor which uses GPIOs 7, 9, 10 and 11. Will the SPI communication work while the Unipi board is connected?

According to the documentation (http://unipi.technology/wp-content/uplo ... ual_en.pdf) these pins are used for Digital Input so you would have to make a custom cable and disable their usage in evok.conf.
Otherwise you would face issues like this: viewtopic.php?f=14&t=57

Thanks Tomas!
I'll use my custom software so that part isn't a problem. I was just wondering if switching the digital output will somehow affect the optocouplers (or if phototransistor in optocoupler will interfere with my SPI communication).

I think it should not affect it unless you somehow switch the optocoupler. But I recommend making a custom cable between UniPi and RPi so you do not need to take care of it

That's exactly what I'll do
Thanks again for quick reply!
