Cmos 4006 for N64 to PC interface
Protolisk,
This does not seem to involve use of a PICAXE in any form.
Since the two 40056 IC’s are connected as nothing more than a 33 stage 1-bit shift register, why not be novel
and look at achieving the same result with a PICAXE
.
Data and Clock as signals into the PICAXE and one signal out.
EDIT:
okay seems I can answer the question myself . . .
Sending $01 to the controller makes it respond with 32 bits of button information.
Note that the controller responds VERY QUICKLY -- within 2 to 3us.
each bit has a duration of 4us (3us lo & 1us hi = 0 and 1us lo & 3us hi = 1).
so whatever you're using to talk to the N64 controller has to be very quick.
An 8MHz PIC would have a difficult time doing this. Better to use a 10-20MHz one and bit-bang it.
