We are planning to
use the 40-pin header on a chestnut board to control a few devices. We are
using an LCD/touchscreen connected to the Chestnut board, so several of the
signals (eg. CS0) are not available for our other devices, and we are finding
that we are becoming severly I/O constrained.
Does anyone know if
the SPI hardware and linux drivers on the Overo Fire can support multiple
devices on the SPI bus. Specifically, can I use CS1 and share the other
SPI signals with the LCD board?
