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

• pyserial3.5
• To build and flash: Use 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 --> Jtagulator style (or JTAGEnum)
• ARM SWD pinout detection --> Jtagulator style
• UART pinout detection --> Jtagulator style
• Find a way to detect multiple devices in chain
• Option to insert ir,dr to a specific device in chain
• Set verbosity options
• Wrap print functions ?
• Move function descriptions to header file
