Hi all, I am working towards designing motor control system using motorola HCS12 MCU. Just bought Codewarrior Standard edition as development environment and expecting DP256 evolution board in 2-3 weeks. To reduce the development time I am planning to use Codewarrior PC simulation to understand and simulate few of HC12 peripheral components like SCI, CRG(clock and reset generation), ADC and PWM. I could simulate SCI quite easily. I could program the registers for specific baud rate and view the data in visual tool 'terminal'. And to some extem I could simulate CRG behaviour and could generate RTIs. My question is, can I simulate ADC, PWM similarly using visual tools like Bar, Chart etc. ? If simulation is possible, can someone provide one example. ( I have tried Processor Expert to generate the programs fast but no help ) Any help in this regard is highly appreciated. Warm Regards MDN |

Well, if you can do it so that it means something, I would sure like to hear about it. I think every simulator has some screwball method for simulating I/O that will run data in and out. The problem is that you can't simulate what you don't understand. I am referring to noisy interrupts, and random characters (in the case of the SCI) and pulses that are too short/long to measure (PWM) and the other detritus of everyday living. On the other hand, I'm not familiar with Bar and Chart. How would they help?

I'm not familiar with the bar or chart either. I'm guessing that
they are "components" in the True-Time Simulator and Real Time Debugger, but I've never been able to figure out how to use them. I recall using a graphing feature, so one could see the analog representation of a changing variable using (what is now TI's) Code Composer. It was pretty cool and I always thought it to be a useful tool. So I have tried to use the advertised "components" in CodeWorrier, with totally no results, as usual. Actually, the Hi-Ware tools are usually pretty good, if you ever figure out how to use them. I'd appreciate some tips. Please don't tell me to read the "Manuals." They're indecipherable. That's what I used to get from the official CW help people, before my warranty ran out.

Thanks for the response, Since I have 2-3 weeks to get by EVM thought why not try simulating some of the MCU peripherals of my interest. Documents available on web with regard to this are very few and they are not at all exhaustive and more of confusing. One document says 'bar' ( acts as a potentiometer ) can be used as ADC analog input and use any other componets like 'static text' to read the digital value from data register. Easier way to create this setup is using processor expert beans. But it's not explained how to configure 'bar' as input ADC channel instead one example in the document configures 'bar' as 'memory' by associating it to ADC data register itself, which is not at all practical. Moreover processor expert generated program does not work unless you do some modifications because it looks like processor expert generates program for actual target not for simulation. This True-Time Simulator is total mess and not of much use. As Gary told you can't simulate what you don't understand. I am just planning to stop spending time on this and speeding the procees of getting EVM. It seems like using processor expert I can reduce the develpoment time to some extent. Can some one suggest me the way to test a set of peripherals ( SCI, CRG, ADC and PWM ) using one simple test program. If someone can pass on the program it would be of great help. Thanks in advance.

MDN, Maybe it would be appropriate for you to invest in good debugging tools that allow you to actually test your code on the actual silicon rather than attempting to simulate it using a simulator. Using a BDM you can test the peripherals on your target board. Even better but more expensive is a full-emulator, that offers many benefits over a BDM including the ability to test your code on the actual silicon even before you have designed or received your target board. Once you receive the target board, you can plug it to the full-emulator and continue to the next step of your debugging. You can read the following articles to get more details: http://www.nohau.com/products/hcs12_emulator_features.pdf http://www.nohau.com/appnotes/hcs12bdm_emulator.pdf Hope this helps, Doron Nohau Corporation HC12 In-Circuit Emulators www.nohau.com/emul12pc.html At 09:26 AM 8/6/2003 +0000, you wrote: >Thanks for the response, > >Since I have 2-3 weeks to get by EVM thought why not try simulating >some of the MCU peripherals of my interest.
