Hello, I'm new to this forum, I recently obtained a 56F8300DSK Demo board (with a 56F8323 on board) and I have been struggling to get it up and running. I have managed to write a simple program that toggles an LED (I have also achieved this using the Processor Expert function) but I am currently unable to get a PWM outpur (either using PE or not). I have tried numerous register configurations without success, it doesn't seem like it should be very difficult to get going as there are not that many registers to set up. I would appreciate any suggestions anyone has, hopefully somebody may be able to provide some register settings from some working PWM code. Cheers PS Does anybody know of a source of example code for the 56F83xx processors, I haven't managed to find anything so far. |

Hi to everyone, people! I'm building a equipment using 3 dsp56309 boards with a "supevisory" microcontroller unit. I must fit dsp firmwares on microcontroller flash, and it will handle boot via SCI port over 3 dsps... How I can obtain simple binary loadable code ??? I try many SREC.EXE options but never I obtain simple code.. example : If I have my program org p:$0 jmp $100 I should have a simple sequence to boot from SCI as: <lenght of program> <adress to star boot> 0AF080 000100 ... ... <end of program and so on....but srec generetaes only standard S3 format with many controls, carriage ret and crc ... do you knpw a method to obtain pure 24 bit word code to fit in flash without loss of space ?? thank you in advance, people!

You might write a loader that you load first into the micro (if it's
loading the DSPs from the flash memory) that strips off the controls and creates
an image that is pure binary from what is sent to it from the outside and that
it stores in flash memory as pure binary. It can then load the DSPs.
I did this kind of thing in the past for DSP56009 and M68HC11.

Attaching a conversion program that runs in MSDOS.
S2bin101.zip. have never used program so I can't
guarantee the end product.
Hope it gets through. If not it will be Friday 6/11 before I will be
back.
P.S. Scanned zip file with NAV. Virus defs updated this AM. Reported
Okay

Thank you to everyone, guys, and to Stuart. Your utility srec2bin works fine and it is exactly what I need. I tested it.. and it creates pure binary sequence ready to load in flash (only 6 initial words must be added) to obtian a Dsp5630x bootable program ready to fit in flash.. Thank you again !!!!! (Note - I cannot use asm utilities due to my architecture.. a ECOG controller handles flash memory; it contains more firmwares ready to load on 3 dsps... With this utility I can obtain on one shot loadable code :-) --- Stuart Brooks <> wrote > Attaching a conversion program that runs in MSDOS. > S2bin101.zip. have never used program so I can't > guarantee the end > product. > Hope it gets through.
