NES controller?

[picaxester]

Has anyone used a NES controller with a PICAXE before?
By the looks of this page, it would seem easy to do.

Can the PICAXE even see a 12 uS pulse? Detect the leading edge?

Doesn't it have to be in a sense loop at the right time to see it?

I got it working

Heres a simple test program:

symbol datapin = pin3
symbol clockpin = 2
symbol latchpin = 1

do
pulsout latchpin, 1

for b0 = $50 to $57
	poke b0, pin3
	pulsout clockpin, 1
next b0

sertxd ("BUTTONS", 13, 10)

for b0 = $50 to $57
	peek b0, b1
	sertxd (#b1, 13, 10)
next b0

pause 500

loop

Heres another site with a bit more info.:
