Adafruit has this week announced the arrival of the newly improved Programmer Shield for Photon which is now available to purchase priced at $30 and takes the form of a USB-JTAG converter that gives advanced users complete access to the Photon’s memory space.
The latest Programmer Shield unlike the previous shield is now fully stand-alone and requires no third-party programmers, and developers can enjoy a JTAG interface as well as a USB to Serial converter. Adafruit explains more :
Do you want to gain complete control over your Particle device right down to its every bit of memory space? or watch as your code gets executed and debug it? Then this shield should be able to pacify that control freak inside of you.
Designed for use with the Photon, backwards compatible with the Core. It supports openOCD and the WICED SDK, and is built around the FT2232H high speed USB FIFO.
This is a FT2232H based JTAG programmer shield that is compatible with OpenOCD and Broadcom’s WICED IDE. The FT2232 chip is setup to provide an USB-JTAG and USB-UART interface simultaneously. The FT2232 can be also reconfigured by the user by reprogramming the on-board config EEPROM. The unused pins are clearly marked and broken out into easy to access header holes.
