I'm fairly new to using the HC12. The tools I'm using is CodeWarrior and the Multilink BDM. The BDM doesn't seem to be working correctly as a debugging tool. Breakpoints only seem to work sporadically and when I try to single step the processor seems to jump off into never, never

I want to use a Pierce Oscillator (with a 20MHz crystal), but it doesn't work for some reason. Does anyone know where I can get more information or schematics on how to do this together with the HCS12? I'm using HCS12DG256 and the Codewarrior compiler.

Gilles/anyone who can answer, I've been using CodeWarrior for the HCS12X v 4.1 for about 6 months or so and I've occasionally had questions that it seems the documentation couldn't address. Maybe it's just that I don't know where to look for the documentation but the Metrowerks website seems to be lacking documentation for the HCS12X products. Anyways, sin

Hi, I am using CodeWarrior 3.1 and also use the banked memory model on a 9S12DP256. I would like to know if it is mandatory to allocate at least one segment in a NON-Banked location. Right now, my prm looks like this : - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - NAMES END SEGMENTS

Hi, I am very new to microcontrollers. I am using a MC9S12DP256C on a trainer board. To develop I'm using CodeWarrior and C code. It is all overwhelming. I am trying to write a program that will compare two voltages and depending on which voltage is greater to send a digital signal to a stepper motor controller. My biggest problem stems from interfacing. I dont know how to initializ

Hi guys, OK finally resurected this old post, you may remember that I posted this saying that I was looking for a freeish tool chain for the S12 for students and hobbyists, well it is finally here. OK, I wanted a 64K solution but after some arm twisting we have now got the free Special Edition of Codewarrior up from 12K to 32K. You can download it here

I have the same code in 2 different projects, in the main loop of both. This section of code has a switch statement in it, but in one project, it works, and the other it doesn't(always goes to the first case). The code is identical except for some port changes due to outputs bein

Gilles, Cheers for your service. I had been critical overnight of the Metrowerks service pages, but as usual this forum has proved worth its weight. The algorithm plugged in a ran nicely. My alternate solution from last post last night didn't work and I had resorted to copying the table with a runtime function into EEPROM when it detected the

I'm using Metrowerks CodeWarrior for HC12. The HC12 has a couple of cool new instructions for interpolation, TBL and ETBL. Is there some way that the compiler will use these instructions, or do I have to roll my own? I looked in the "manuals", to no avail. Thanks, Bob White
