I have an Anvyl board and I want to design logic to use the HID PS2/Keyboard interface on the board. Is there any additional specification for the Keyboard interface beyond what is in the reference manual? The reference manual data is incomplete and inconsistent with PS2 interface specifications that I have found (specifically most PS2 interface docs specify that the Keyboard drives the CLK line when the Host sends data to the Keyboard. The Anvyl reference manual implies that the Host sends data to the Keyboard by driving both the CLK and DAT lines). Since the PS2 interface is implemented in code on the PIC uController there should be some documentation (worst case the uController code itself). If you do not have documentation beyond the reference manual, would you provide the source code for the uController?
It looks like the uControllers can be programmed using connectors J15 and J16. Will you provide information about how I could (re)program the uControllers (what programmer do I need to purchase to write my own code and download to the uController)?
