HC12 Welcome Kit
Welcome to the world of HC12!
Explore the HC12 Universe!
Looking for a compact, ready-to-use HC12 controller module? Want a 16 bit controller module with on-board RAM, EEPROM and two serial interfaces at a reasonable price? Would you like to work with state-of-the-art microcontroller technology? In that case you should have a look at our HC12 Welcome Kit!
A powerful yet easy to use hardware platform is the best basis to learn how to program a new microcontroller. This is the main idea behind the HC12 Welcome Kit.
HC12? No problem!
The "good old" HC11 did not cause much trouble - the DIP or PLCC packages of these devices where easy to handle. The LQFP112 package of the HC12 (0.65mm pin spacing!) is a lot more demanding. We deliver the HC12 Welcome Kit with the MCU already soldered on the PCB so you do not need any special soldering and handling equipment! No bad junctions, no unreliable sockets, no problem!
Plus: the HC12 Welcome Kit is much more than a simple socket converter. With 4 KB EEPROM there is more program memory you ever could find on a HC11 (except for expensive EPROM or OTP parts). 1 KB RAM, two RS232 interfaces and nearly 80 inputs/outputs are available. You might even add external memory (8 or 16 bits data bus) to the kit - all peripheral signals are available via two header connectors.
From HC11 to HC12
The new HC12 controllers contain the CPU12 core, which has its roots in the HC11 architecture. The CPU12 core has many additional and improved features although it is still compatible with the HC11 on source level. Control register names, mnemonics, adressing and operating modes sound very familiar to the HC11 user. Additional features are:
You may write your own assembly language programs using your favorite ASCII editor and the AS universal assembler which is included in every kit. You will also need a way to download your code. For this purpose we supply the TwinPEEKs monitor program. This software is already resident in the internal EEPROM when you get the kit. It occupies 2 KB of the EEPROM space (so 2 KB are left for your code). The advantage: You will not need any (more or less expensive) BDM tools to download your code!
The monitor program is also suitable to display and modify memory and to start your application program in real time. The monitor is write protected, so you will not erase it unintentionally (of course you can overwrite the monitor code and use the entire EEPROM space using an optional BDM based programmer).
Accessories/additional HC12 products
For C software development we recommend the ICC12 ANSI C Compiler by Imagecraft.
A helpful addition is the ComPOD12/StarProg BDM In-System Programmer.
