Im currently drawing the schematic for a audio board im going to build.
I have one little question :)
I have five spi devices on the spi bus, each one has its own CS pin (four used by 2x mp3 decoders and the other used by dataflash)
I have not chosen PIN 10 for any of my device CS pins
As far as im aware as long as i set PIN10 to an output (stop spi goin into slave mode) im ok!
My question is after i set pin10 to an output can i use it for some thing else (not a cs pin) like flash an LED or some thing?
Iv used all the io in my design and pin10 is the only one left :(
any help much appreciated :)
