SPI communication with multiple slaves

[electrolab]

Hello guys!
I am new to the Olinuxino world and i want to communicate via SPI with 5 of SPI slave devices.
I am using the GPIO-3 connector which has the SPI_CLK SPI_MOSI SPI_MISO and two SPI_CS.
The fact that it has two SPI_CS means that i can only setup only two SPI slaves?
Or i can setup other pin for slave selection ?
Thank you guys for any kind of help!

Hey !

I don't know where you are with this, but you can use GPIOs to select the slave you want to talk to. You can even use a MUX/DEMUX, or an address decoder so that you can use 3 GPIOs to address 8 slaves.

CS are in general active LOW, so don't forget to put a pull-up resistor on it.

Hope this helps.

BTW, does your nick has something to see with this : http://www.electrolab.fr/ ?
