Doug Brown	1595c69890	OK -- so I separated the actual port code from the external memory controller code. I think this makes more sense. ... It does add some complexity to the code. I may be going through a chain of calls just to turn the CS pin on, for instance. Hopefully I'm not going too crazy with this. Anyway, this means that I can control the ports from a SIMM electrical test routine using the same types of functions that the actual programming controlling code would use, without having to duplicate a bunch of port definitions and bit manipulation. I made sure to add all the functions I can think of needing to the ports module. We'll see if I got them all!	2011-11-27 00:01:29 -08:00
Doug Brown	4c51019e30	Moved the common "read/write register A and B together as a 16-bit ... value" functionality into a read function and a write function. Also added ability to set pull-ups.	2011-11-26 22:17:17 -08:00
Doug Brown	407f6831a9	Initial import of my test code for the SIMM programmer board. Right now ... it contains an (untested) MCP23S17 driver complete with AVR SPI support, and an (untested) external memory interface driver that uses it.	2011-11-25 23:10:30 -08:00
