Hi henrik ,

I have the option of using the hardware spi for the cpu driving 2 x spi bused devices ( SD Card , RF module) with individual select pins for each.

to date i have found the shiftout/ shiftin arrangements have worked well for the RF spi device and i have the code
but not tried its with 2 or more SPI , so far or used the registers for the spi HARDWARE.

i am wondering is there any advantage for multi SPI devices to use the hardware SPI than just use the software SPI in this case , and getting it to work using the hardware SPI

Cheers

Sheldon
