Can I use an NRF24L01+ and a TouchScreen with Pi Zero?

I've never used the NRF24L01+ module before, and I want to use it to communicate with some PIC controlled lighting. I also want to use the Pi with a touchscreen. Both need the MOSI/MISO pins - does that essentially mean it's on or the other, but not both?

Multiple SPI devices can be connected, you just need to connect each to a separate Chip Select line.

Thanks.

So I connect the MOSI/MISO/SCLK in parallel, and since my touchscreen is using CE1 on the GPIO header, and can't be changed, I need to simply recompile a library for the NRF24L01+ that uses CE0?

(I say simply, it looks daunting, but I'm determined!)

It might be that simple. Depending on the NRF24L01 library you might just be able to tell it to look at a different device on the same port.

For example python-spidev the syntax is

Code: Select all

spi.open(bus, device)

Which will open the spidevice /dev/spidev<bus>.<device>
