How to handle multiple spi devices


I like to control 3 spi devices within one project. It seems to be only one instance of the spi-class per spi-Port allowed ( ‘System.InvalidOperationException’ when I try a second new SPI(… with the same spi-port in the spi.configuration). Does this mean, that I have to destroy and to construct a spi object when I want to change output to an other device with different CS-Port? The member ChipSelect_Port is read only. The only practical way I see now, is to handle the CS Pin by my own? Is this right or are there smarter (and most important faster) solutions?


You will have one SPI object always but then you have multiple configurations, one for each device you have.

Here is a good example
