Hi all, I am using the Soundbite development board, with DSP56371 chip. I'm using the Symphony Studio, to write the code and to debug. I am having trouble with this piece of code, I wrote: ...

I am using MC56F8013. I am very familar C30 complier of Microchip MPLAB. In C30 we can access any register with simple keywords. When we include the appropriate header file we can access any registers. For example ADCON1 register can be accessed with: ADCON1 = 0x1234; value = ADCON1; And any port pin can be accessed like this: _LATC13 = 1; will make port bit 13 of port C. We c...


56F8013 Serial Bootloader

I am starting to develop a serial bootloader for the 56F8013 and I have come across with the documentation of the bootloader that is "pre-loaded" on the 56F8013. From my understanding, the bootloader copies itself from Flash to RAM, then runs out of the RAM to erase the Flash and write the Application code. However, it "erases" itself in the process which would prevent further bootloading. ...


Symphony Studio 56720 Simulator -- simulator command script file

Hi, Thank you for your replies. I can't get this to work. I'm using the example in APR35 section 2.2.1. It runs correctly reading and writing to memory but not to the I/O files. I've modified the simulator script according to appendix B of the DSP Studio User Guide (I think I've read it correctly??) and tried all sorts of combinations. So I think the problem is with the simulator comm...

Hi, I've started to use Symphony Studio 56720 Simulator and can simulate simple C programs, like the C-Tutorial in the user guide. How do you simulate input and output signals? Any insights, documentation or code examples would be very much appreciated. Thank you for your help. Cheers, John.


Boot to the head, please. Thank you very much.

Hi guys, I am designing a phase shifted PWM DC/DC converter for a fuel cell. I would like to use an average current mode controller to control the voltage out put by controlling the current using a double loop controller. I am thinking of using an analog Phase shited PWM controler IC for the current controller whose set point is generated with an external current programmer with con...

Hello everybody!... I'm new here, and I have some problems with a motorola DSP56307evm board. I'm doing a proyect that implements real time digital filters with the EFCOP co-procesor and the CS4218 codec. I've implemented that. But now, I want to change the coefficient table using RS232. I'm using tasking compiler and I use the RS232 library (serio.c - serio_in.c - serio_out.c and serio.h) b...

I hope that the solution is already covered by my last email. Be aware that all files are imported into the project specific subdirectory in your workspace. The files imported there are used to build your project. Don't change the paths here, this will mess up the whole thing. If you have problems, delete the whole project from your workspace and set it up as recommended by my small 'tutorial'....

I keep getting this error in the debug mode of Symphony Studio, "source file not found." I read a tutorial that had a troubleshooting section that explains how to fix it. I followed their directions, which don't seem to make that much sense, and I've tried creating new path mappings and varied it countless times to no avail. There are two fields in the path mapping specification, "Compilation p...
