Hi,

I am new to DSP world and know nothing about the embedded software 
development so far.

I am targeting for DSP56L307 chip. I am wondering if anyone who has 
the development experience of this chip can give me highlights of the 
development environment and RTOS that can run best on the chip. Is 
CodeWarrior compatible with this chip? Do I have to buy a command 
converter? what kind of file format (COFF?) the chip can support? Any 
performance panelty if I write the DSP code in C rather than asm?

Thanks,

zhongsheng

Dear Zhongsheng,

A few years ago I designed a product based on the L307 (but I changed to 
56311 later, and would now use the 56321 for a new design).

The Motorola-Freescale EVMs come with the CLAS software that includes an 
assembler, linker simulator, C compiler, and debugger. I have not used 
the C compiler, but am told that if you work at it, it can be useful. 
All my work has been in assembly language using the CLAS tools and they 
work pretty well. These software tools are free and available on-line at 
freescale's web site.

I use a Command Converter that connects between the PC's parallel 
printer port and the EVM (or your own target hardware). The object code 
format is, I believe, *.CLD format.

If you are interested, I have a L307 (and a 311) EVM  (software 
included) for sale for $150 (150USD) plus shipping. I do not have an 
extra Command Converter to sell.

I have no experience with an RTOS for the L307.

Best wishes,

Chris Moore
