GP32 Gp32 keyboard serial source code here...maybe?

[NiN^_^NiN]

Ok after looking at the serial port and all the other post for keyboards i found this site.

http://jtag-arm9.sourceforge.net/

Now the serial port on the gp32 is jtag and i found a guy who has source code for jtag on a arm9 cpu seams like its for all arm 9 processes B)

This should be able to give us an idea and a place to start on making keyboards work or other hardware through this port.

The serial port uses JTAG to communicate.
Pins: 1=3.3v 10=TXD0/GPF2
2=nRESET 11=IIC-bus[SCL]
3=nTRST 12=IIC-bus[SDA]
4=JTAG[TDI] 13=nRTS0/GPF4
5=JTAG[TMS] 14=nCTS0/GPF5
6=JTAG[TCK] 15=RXD1/GPF1
7=JTAG[TDO] 16=TXD1/GPF3
8=AIN0 17=NoConnection(?)
9=RXD0/GPF0 18=Ground

Also i dont know if this would help any1 but..

these guys have the stuff for hardware like a ethernet board using the port with linux so u might be able to network the gp32 when linux gets installed on it

I'm dashing h34r:

JTAG is a different thing actually, but there is 2 UARTS in the EXT connector, and afaik DF have some code for it.
