July 17, 2007: New version 3.40 of AsmIDE was released

Pluto Visual Debugger for the Serial Monitor

Linux Downloader for the Serial Monitor

Chase Douglas developed a C language downloader for linux that can program flash from an .S19 file. This works on chips that have the serial monitor, such as the C32, C128, E128, and NE64. This open source program is currently being maintained by Mike Morgan and you can get the latest code from his wiki. This has the C source code and a Makefile for use with the linux gcc compiler.

Dirk Heisswolf's HSW12 Assembler

Dirk Heisswolf wrote a free assembler called HSW12. This is an interesting free assembler for the 6812 that you may want to check out! This is supposed to support the extra instructions in the S12X. Email me if you like this and you want better support for it in the future.

Introduction to AsmIDE

I'm a Windows programmer with a background in electronics. I wrote some Windows programs for use with the Freescale (formerly Motorola) 68hc11 and 68hc12 families of embedded microcontrollers. I use a Dragon12 board with a hcs12 (68hc12 family) processor, and an EVBPlus2 board with a 68hc11E1 processor. Both AsmIDE and EmbeddedGNU work with these boards, and most other boards based on the 68hc11 or 68hc12.

AsmIDE is my freeware, Open Source, Integrated Development Environment (IDE) for the 68hc11 and 68hc12 families of embedded microcontrollers. This gives you the ability to edit your assembler source code with a syntax-highlighting editor, and it can run a command-line assembler for you. Lastly, it has a terminal window to let you interact with your microcontroller, and it can download your .S19 files to the microcontroller.

AsmIDE now comes with free assemblers for both the 68hc11 and 68hc12. It also supports the proprietary 68hc11 debugger and 68hc711 programmer from Wytec.

AsmIDE gives you a nice way to develop assembler programs on a Windows PC, and it lets you interact with your embedded development board by entering commands in the Terminal window.

The 9S12C32 - easy to program flash!

This new series of controllers is opening new possibilities for embedded applications: MC9S12C32 MCU from Freescale (formerly Motorola) This is a very nice improvement over the older versions of the 68hc12 microcontroller. The 9S12C32 is the first member of this new 9S12Cxxx family of chips. This new family of devices makes it easy for hobbiests and students to program flash memory over their PC's serial port without the use of a BDM! Its built-in serial monitor doesn't have an ASCII set of commands, but it can be programmed by both AsmIDE and EmbeddedGNU. In order to do interactive debugging on this family you have to use another program, like the free ubug12 from Technological Arts, or my Pluto debugger, or you can use a BDM background debug interface.

Technological Arts has a line of boards based on the 9S12Cxxx family. They call it their NanoCore12 family.

Wytec also has a line of boards called DragonFly that is based on the 9S12Cxxx family.
