Thanks Lukas, as I have to switch between the SPI Clients (RTC,SD,Ethernet) in the software I would need the PIN’s for chipSelect. I think the PIN for SD shall be 53. But in the PIN description there is no PIN Number for RTC/SS and ETH/SS??. Please help.
regards
Maggo
P.S. To run only the RTC+Ethernet togehter is not a problem it works fine, without switching the SPI Clients
