Maximum number of SPI devices.
Hi,
I'm new to mbed.
Is there a limit to the number of SPI devices that can be hooked together to a single mbed board assuming that there are enough IOs for selecting the right device.
thanks
Gilad.

Short answer: No.
Longer answer: There are of course some practical limitations. Probably most relevant will be that if you really start connecting large numbers of devices to a single SPI bus that the load becomes larger and larger, and that might be a limitations if you want to use the bus at high speeds.
