Hello, In codewarrior evaluation version (Special Edition), can't you use beans? Thank you! _________________________________________________________________ ...
... beans? I think that 'basic beans' can be used. Read this: http://www.processorexpert.com/hcs12/metrowerksinfo.html But I am not sure. When I launch 'beans...
Yes, you can. See http://www.metrowerks.com/MW/Develop/Embedded/HC12/Processor+Expert.htm The Special Edition is not the evaluation version. But in both you...

The basic beans can be used, however only if you have a license file. You do get this license file for the special edition by registering at the Metrowerks web...

Thanks for the effort Edward, but your reply didn't really help me understand my problem. Perhaps I didn't express myself clearly, so it looks like I will have...
Steve, Instead of using the PWM, why don't you use the timer module. In the original HC12A4, there was no PWM. You could however setup TC7 as the timer period...
You can use PWM concatenate mode to get 16 bits of resolution. This will cut your number of channels in half, but is the easiest way to control an RC servo....
Hi The PDF shows PRO and SPC/SPC* in the colums, I guess the PRO stands for the Professional Version, the SPC stands for Special Edition and what is the *...
Hi, I use the Output compare feature to drive RC servo. Prescale the timer by 4 and you will get a 2048 steps resolution and 20 ms period. Works great. Mike ...

Ups, formulas should have floor probably (largest integer not greater than) instead of ceil. And T0=2^16 / ECLK=8.192ms N=2 ^ floor(log2(Tpwm/T0))=4 ...

What is the maximum expected data length for S19 records ? I found that program data records (S1, S2) are typically 32 data bytes long, while S0 record is...

There is no length limitation defined for S-Records (to my knowledge). The S0 record is a 'descriptive' one, and usually contains the file name. With...

I am not aware that S-records have any inherent limitation except for the size of the length descriptor (two bytes). However, there are two practical ...
