* Dragon12 Homesite - homesite for the HCS12 development board used in the EE3176 labs.
* Freescale Semiconductor - Freescale (spun off from Motorola in 2004) is the new name of the compan y that makes the HCS12 chips the we use in the labs. There is a lot of useful information on their site, especially application and design notes covering various practical implementations of the HCS12 chips.
* Elektronikladen - makes a variety of HC(S)12 based development boards, and hosts a number of interesting HCS12 projects.
* Technological Arts - This company makes many HCS12-based development boards and systems.
* PE Micro - makes hardware debugging systems for the HCS12, including affordable BDM systems.
* NoHau - makes advanced debugging equipment for HC(S)12 systems, including in-circuit emulators.
* SoftTec Microsystems - makes a variety of development tools and software for the HC(S)12, including the inDART debugging system.
* Axiom Manufacturing - has several HC(S)12 based development boards and tools.
Software
* Metrowerks - Commercial website for Code Warrior, a fully integrated environment (compiler, assembler, simulator and debugger) for developing HC12/HCS12 programs. Metrowerks is a Motorola owned company.
* Code Warrior U - Code Warrior University online features a Code Warrior Tutorial for Windows. The course requires registration, but is free.
* Simulator for the HC12 - Free, JAVA-based simulator for Freescale Semiconductor* 68HC12 from Tom Almy.
* GNU Development Chain for 68HC11 and 68HC12 - Free, Linux-based GNU development tools for the HC11 and HC(S)12. Includes compiler, assembler and debugger.
* Imagecraft - has the ICC12 C compiler for the HC12.
* Mini-IDE - Free IDE for assembly based systems for the HC(S)12 from MGTek. There are many other useful HCS12 resources on this site.
University Programs
* New Mexico Tech EE308 Microcontroller Course - This is a great website featuring much useful information about the HC12/HCS12. Check out the lecture and lab notes.
* UT Austin - Jonathan Valvano - Home page for the HC12 based microcontroller classes taught by Jonathan Valvano. Includes lectures and labs in pdf format, and his free online C book for the HC12. Well worth visiting.
* WWU Embedded Server Site - Todd Morton's site at Western Washington University has a number of useful HC12 based labs and projects.
* Tech Online - Tremendous (and free) site with many EE tutorials and articles. They offer an online course that describes the Code Warrior IDE. This can't be bookmarked, but can easily be found with a search once you're at the Tech Online site. The course only takes a few hours. There are other embedded/microcontroller courses on the site which may also be of interest.
* The Art of Assembly - Excellent and free online book covering the Intel assembly language in detail. Though geared for Intel/PC assembly, its helpful for microcontroller systems as well.
* Understanding Small Microcontrollers - Free online pdf book (332 pages, 2.8 MB) by James Sibigtroth of Motorola. Though geared for the Motorola HC05 chip, most of it applies to the newer chips such as the HC08, HC11 and HC12/HCS12. This book is well written, and is a good resource for learning the basics of Motorola-based microcontrollers.
* CMX - This company has several useful software tools for the HCS12, including an RTOS and a commercial (fee-based) TCP/IP stack.
