Arduino JTAG/IEEE-1149.1 (1990) Standard Driver for Low Level Purposes

Brief

Simple low level JTAG driver implemented on the Arduino platform. Controlled by a python3 host via the Serial0 UART interface of the Arduino.

Requirements

• pyserial
• Arduino IDE that supports the DUE platform

Notice

• Cannot be used on Arduino-Uno because it has not enough SRAM for the program to run.
• Use a different platform with more than 2KBytes of SRAM. (Use: Mega, Due ...)

Future Work and Features

• JTAG / IEEE-1149.1 pinout detection
• ARM SWD pinout detection
• UART pinout detection

• implement the jtagulator algorithm
• find a way to detect multiple devices in chain
• option to insert ir,dr to a specific device in chain
