Hi pitchayav, The two places I would look for answers to these questions are the Freescale website for the EVM or processor in question, which may well have examples, tutorials, and appnotes, as well as the File->New-> Processor Expert Examples Stationery selections, which cover a wide-range of different DSP functions. Some of the calculations you are describing may be under the Signals branch of these examples. Hope this helps, Ron -- Ron Liechty Ombudsman Freescale Developer Technology ron.liechty@ron.... -----Original Message----- From: motoroladsp@moto...

Subject: [motoroladsp] Can someone navigate me what should I do to start developing with DSP56F801? Never before, I am new for DSP developing. I have just study some materials which are linked from Freescale website. Those included with how to use CodeWarrior and some information about the processor, but I have some questions to ask about: 1. Where can I find any tutorials or any example source code (in C) about the basic programming of DSP56800 family such as "What are the functions of each register in DSP56800 (That I meant mainly about ADCs) and how to use it?"? Or the other method which use Processor Expert, are there any training documents or any tutorials? 2. Are there any set simulators for DSP56800 family such as "Proteus ISIS Professional" for any micro-processor controller? I have use DSP56F801, but I didn't have DSP56F801EVM yet. 3. Does math library in the CodeWarrior support for calculation of transfer function and determination of crossing point of 2 non-linear equations? If not, what is the library which supports these operations? If someone know, please reply me. Best regards and Thanks a lot for your help Pitchaya V.
