HELP? Beginner

[yitlilee]

Hi, I am a beginner in Freescale MCU, can anyone give me a direction where to start? I have little knowledge in PIC, wondering is it similar to Freescale MCU? I am currently starting with MC9RS08KB4, what compiler, programmer, simulation software needed?

Don't have any PIC experience, but just wanted to let you know that CodeWarrior is all you need for a compiler and comes with a simulator/debugger.. It is free for the most part unless your image is above a certain limit. You should get USB BDM Multilink for a programmer, sooner or later.  There are plenty of example projects. I would recommend using Processor Expert to build your first projects. Once you watch some demos and learn how it operates you'll love the flexibility.

I am facing a problem, MC9RS08KB4 is not supported by Processor Expert in CodeWarrior, how can I solve this problem? Install update? Where and which update should I install? Thanks.

Urgent! Please help!

One question here, is that I need to connect with USB BDM Multilink to check the simulation result? Is that any circuit simulation software can be linked to CodeWarrior for circuit simulation? And what is the difference between CodeWarrior and Processor Expert?

[Andrey]

USB BDM Multilink is for programming/debugging the hardware. If you just want to run a simulation you must select Full Chip Simulation under default connection.

You can open a Visualization Component (in a debugger window select Component->Open->Visualization) which will allow you to do some circuit simulation (e.g. LED light, dip switch). However, I found it easier and faster just to set some variables to watch.

I would recommend buying a book or attending a Freescale Technology Forum as they have lots of training sessions.

And altogether it would be easier to start with a demo kit with some sample programs.

Thanks for reply, Andrew. I couldn't find the setting that you mentioned. I am using CodeWarrior Development Studio for microcontroller Version: 10.2. Are you mentioned the same setting as in this version? I found that many version of CodeWarrior, which is the best? Is that any circuit simulation software link with codewarrior? For example, proteus isis circuit simulation software with MPLAB microchip, so that i can see the result by manipulating in circuit?

[Andrey]

You need code warrior 6.3. Different versions are for different MCUs.

Hello,

I notice that you have selected a device from the MC9RS08 family.  This family quite has limited functionality and resources compared with other 8-bit families.  For learning purposes, it would be better to choose a member from the MC9S08 family, preferably using a suitable demo board.  The demo board will contain an inbuilt BDM multilink for flash programming and debug.
