Welcome to the tjtag3-0-1_arduiglerHID wiki!

This is modified version of JTMOD to be used with arduino HID

make sure to include the /wiggler switch with your fav options?

Usage: If HoodLoader2 is not installed then install it first onto your ATmega16u2

PIN Connection: Install the 4 pin header on JP2

PORTD on ATmega16u2 is ICSP header. You need to solder the additional 4 pin header to access all 7 PORTB I/O pins PB4 to PB7 is on the additional 4 pin header.

               |GND|PC1|

JP2 ---->> |PB6|PB7|PB2|PB1| <--- ICSP Header

       |PB4|PB5|+5v|PB3|

PB0 = NC

PB1 =

PB2 = RST

PB3 = TMS

PB4 = TCK

PB5 = TDI

PB6 = TRST

PB7 = TDO

Issues: The communication is very slow, dont know if the arduino is putting out data too fast or other timing issue. If u have any ideas please do let me know.

TODO: maybe move some functions like clockin from tjtag to arduino to make it faster ???
