Repurposing the TI EZ430U
with msp430static, solder, and syringe
USB devices are sometimes composed of little more than a microcontroller and a USB device controller. This lecture describes how to reprogram one such device, greatly expanding its potential.
At only twenty dollars, the Texas Instruments EZ430U is a bargain of an in-circuit debugger for the MSP430 microcontroller. The board itself is composed of little more than an MSP430 and a USB to Serial controller. The board's JTAG fuse is unblown, and full schematics are included in public documentation.
This lecture will discuss the use of the EZ430U, not as a debugging tool, but as a development platform in and of itself. Topics will include the writing of replacement firmware, analysis of the default firmware, reprogramming the USB to Serial controller, and potential target applications.
