I'm currently trying to implement 4 CS in RaspPi. I'm still a newby in this field and used the library wiringPi. For CS0 and CS1 this works totally fine. However now I have 2 more CS on the GPIO Pin 17 and 18 (with same Clock, Miso/Mosi Pins as CS0 and CS1).
I found this tutorial https://adikedia.com/2016/08/10/using-multiple-spi-slave-devices-with-wiringpi/ on how to implement 3 CS with wiringPi, but not sure if this might work in my case.
If I set CS 17 to Low and then call the wiringPiSPIDataRW(CS0, buff, lenght) function , shouldn't my CS 0 also go low? Then which data will be written to my Miso Pin?
Thanks for your help!
