Hi there!

Just a short question - what HCS12 device would you recommend to a HCS12 beginner? I have experiences with other MCU's (AVR, MSP430) and I'd like to play with mighty HCS12 too.
Is HCS12DP256B a good choice? I can see that I can get free samples, Metrowerks IDE (32k limit) and also TBDML should support this one so I do not expect any issues but I'd better ask Smile I am not willing to spend any bucks on it at all - so I do not care about eval boards (with my decent Pixma IP4000 printer, 0.65mm pitch PCB is a piece of cake for me Wink)

Any other recommendations are welcome!

Thanks,

Sounds like a good choice thus far. I am just curious - are you going to be doing a Gootee board? I am interested to hear how this turns out. Also Metrowerks supports an unlimited ammount of ASM should that you desire to program in ASM.

You mean this method? http://www.fullnet.com/u/tomg/gooteepc.htm
No, just an old boring photoprocess. It works great for me and it is reasonably cheap (1-2EUR per half-eurocard). Also note that my printer is inkjet, not laser, so gootee would not work AFAIK.

Yes, I saw that on their pages. I will probably stay away of ASM as I am much more productive in C - not mentioning stealing my code from my AVR projects and reusing them on HCS12 Wink (I've done it with MSP430 too and some code is stolen even from PIC Cool )

I would start witha C32 as you won't get frustrated with the 32K limit of Codewarrior. Rolling Eyes

This also makes sense Smile On the other hand, if I could mix 32k code compiled from C sources and unlimited assembly, I could leverage the assembly code for constants (you know, sound samples, graphics etc.) Maybe I should get both C32 and 256...
