Hello , I have used circular addressing for Ar6 and Ar7 by using BK47 and BSA67 in assembly . I have also used dsplib function 'fir' in the same project in C file. I am finding that BK47 is being modified by the dsplib function fir which is also not restored in the fir function. The fir function also uses circular addressing internally to execute convolution and filtering operations. Also i ...

Hi, I want to use two periodic nested interrupts as follows: when the second interrupt occured while the ISR of first interrupt is running the ISR for second interrupt begins to start without waiting for the first ISR to finish. furthermore after finishing the ISR of second interrupt the program should not come back to continue the first ISR and it should wait for comming new interrupt. Could yo...

Dear all, Please help me my code works without optimization. but when I set it to file level (o3) optimization it doesn't work and it remains for allways in the following while loop. when I investigated the code in mixed mode I saw that the spitobyte() function is deleted in readreg() function. Even when I substituted spitobyte() with its source code compiler deleted some parts of it and it didn'...

I've been having a difficult dsp/bios kernel crashing problem. It always comes, when kernel changes running task to another one. I release currently running task by function like SEM_postBinary(). Then a task with a higher priority should start. Normally everything works well, but when I put one more line into a code, x += 1, or similar, whole thing crashes. It looks like memory fault (stack ov...

Hi I want to create a library from my codes (*.c files) so I wrote them in a project of type library. Is this procedure true? Where can I find the tips and rules for creating a library? Can a C source code, which will be the .lib, have main()function? What should I do if I have the same .h and .lib files both in my created library and in final project (which use my created library)? Regards ...

hello everyone,i have some problem when using i2c of 5502. i just want to send data to some other system,but i can't configure it properly.and no data is on SDA&SCK.When I put i2c out of reset state,both SDA&SCK go low,and i do not know why. i try to use the exammple of CSL of 5502,but it does not work either.i can see there is only 1 byte data and clock,and then SDA&SCK go low again. can any...

If we take a project that is built with the linker option (-c) and try to bootload with it, it works correctly. If we take the same project, build it with the linker option (-cr) and try to bootload with it, it does not start. Both build versions run fine using the emulator. All critical parameters have been initialized to known values like in the following example: unsigned parm_name = 10; ...
