Support in SPI for CS (low-high enable) vs. CS# (high-low enable) #53

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Certain SPI flash chips -- for example, the National Semiconductor
NMC93C56 -- utilize a high CS for selection, whereas SPI.c is hardwired
for low CS.

While two workarounds are to use an inverter or ]0x00[ writes instead of 
[0x00], it would be more consistent to offer an option for the idle CS state 
during SPI mode setup.
