Moin, I just installed this new Symphony Studio from freescale website: http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=SYMPH_STUDIO&fpsp=1&tab=Design_To ols_Tab However, I tried and I am still guessing who and what it is made for. The compiler that is part of it has not improved, still the old buggy gnu 1.37 port, only it says "freescale"now instead of motorola. Still no f


struct alignment in 56800E

I use 56f8366(56800E core). According to a manual for CodeWarrior for 56800E (Targeting_56800E, p. 125 and 126) structures are word aligned (or double word, if they contain any double word variables). Shouldn't that also mean that data inside the strucutres are word (dword) aligned? What I observed is (see comments): struct booStruct{ int dummyInt; char singleChar; char charArray...

Hello, I'm from Argentina and I'm a new user of the DSP56303EVM board with two serial port interfaces (RE10091B rev E); I would want to know if such board includes the pre-loaded Self-test described in the Quick Start Guide, Installation Procedure of the DSP5630EVMUM/AD, Preliminary Document. If not, wich way can I test the correct operation of the board? Thank you for your time

Dear group, I am presently developping a new graphical to ASM compiler for DSPs. The first target chosen is DSP56300. The product is now in it's "beta" version and I would like to compare it's performance to results obtained from normal C/C++ compilers. I measure execution times by hardware on DSP56300 targets. The old GCC56300 is not really a reference for my tests ! Thus, Could ...

Hi, I'm currently working on a project on the 56F8013 DSP. I have implemented all my codes in C to make code sharing and maintenance easier. However, I would like to use Fast Interrupts and only Assemble codes are allowed within the ISR. My problem now is how to access the variables that I have declared in C within the ISR. I have started to go thru the documentations to see ...

Hello, i am trying to dump numerical data onto the serial interface and am being hampered by the slowness of the NumToString routine in C, because of the divisions and remainder functions. Would anyone be able to share an assembly routine for converting an unsigned 16-bit word into 6-character strings ? (the alignment or padding doesn't matter) This is for a 56800E dsp (56F8346) ...

Hi, I am really new at programming a DSP, and a simple task is starting to cause me some trouble. I'm using the Motorola 56807 EVM with Cosewarrior and PE. I want to calculate a simple FFT and transmit the data serially to the PC. The problem is that as soon as I call the FFT function nothing happens? I tested my ADC to serial connection and it worked fine but it stops working when ...

Hello, I am trying to make the uCOS-II (v. 2.76) work on the dsp56807 with use of CodeWarrior 7.0. PE does not provide any example of using uCOS with this CPU so I have: - created a new project for dsp56807 - added the uCOS beam - added the uCOS files to the 'code' directory and to the project as 'user beams'. I also made some minor changes in them (changing to "" in #includes, oth...
