Hi, Kenneth,

Thank you for your help.

> This is really only limited by the amount of gpio's you have available to use as chip select pin, the chip select pin is used to choose the slave SPI you are writing/reading to. So if you want to have 5 SPI slaves, then you need a total of 5 chip select + 3 spi (clock, miso, mosi).

I understood your reply.

Best regards,
