Projects for TI's MSP430 Launchpad

What should we do with the TI's Launchpad?

USBDM_JS16 - Freescale USB programmer

JS16 is a very minimal USBDM version based on MC9S08JS16, that supports HCS12, HCS08 and Coldfire V1 devices. It is easy to construct and may be initially programmed over the USB.

FLIRT - Friendly Little Interrupt Tasker

An attempt to simulate preemptive multithreading on 8bit MCUs.

Light reading for a weekend

The time kills me nowadays, so here are links to interesting projects, at least. Enjoy.

QP: Open-source state machine framework

QP™ is a family of lightweight, open source, event-driven, state machine frameworks and real-time kernels for embedded microprocessors, MCUs, and DSPs.

Pocket PC challenge

Do you remember the old pocket PCs like the SHARP PC-1500, PC-1600 etc.? A small plastic brick with an ASCII keyboard and simple LCD.

USB Host for microcontrollers

It isn't a problem to create an uC-based device as an USB peripherial nowadays - there are a lot of chips with USB device capability, from FTDI to some PIC/USB, or OBDEV's USB software controller. But what to do if you need connect some USB peripherial to your device?

MicroVGA

MicroVGA is low-cost VGA interface, providing 80x25 text mode (800x600 @ 60 Hz) / 16 colors. MicroVGA can be connected to microcontroller, thus it's an ideal solution for embedded applications.

Microcontrollers gotchas

A list of AVR and PIC common pitfalls by Ladyada.

Universal FAT32 library

Very useful library for everyone, who wants to deal with any SD/MMC card or other storage, works with FAT32, in applications such as MP3 players or data loggers.
