Diy Xbox Wireless Adapter - Raspberry Pi Forums

i have raspberry pi 2 , im running retropie.and have xboxdrv working diy adapter old rrod xbox.
has info here: https://dilisilib.wordpress.com/hacking ... e-arduino/

unfortunately doesnt have sync function figured use gpio enable it. first outing wiringpi.
know c best thats why went wiringpi. wired 3 wires. 5 power button, 6 data, , 7 clock.

understand, pull data line down, send 10 bit command , pull data line again. didnt research find commands works on arduino im sure right.

started porting arduino code , cant working reason. c program can tell button or isnt pressed, (tho seems backwards me) digitalread(sync_pin) read 1 when not pressed 0 when pressed.

actual sending of command hangs on clock while loop. ive tried writing several different ways have found , can't it.

ill paste code below, , on github https://github.com/pressy4pie/xboxadapt ... ter/sync.c
sorry still kind of dirty , stuff

code: select all
