We are trying to bring up an new board that contains a TMS320VC33 dsp. After power-up the VC33's H1/H3 clocks are static and the dsp is in a locked up state. TI does have an application note (sgua001c) that describes this behavior in older DSP's. On power-up the dsp would randomly ge

Hello i have a TMS320VC33 DSK i have a question regarding the DSK i am using matlab to generate coefficients uing the remez an FIR1 functions. However i am not getting the correct results and somtimes none at all. i am using a PC spectrum analyser to look at the results. I have the correct setup for the global control register EBF300

I recently purchased the tms320vc33 DSK for my senior design project. I plan on developing my code for the project using the DSK. I also plan on putting together a custom PCB. I'm looking for a schematic of the DSK as it would greatly assist in this process. I can't seem to find it online or in any documentation or data sheets. I'm not sure if I'm missing something as it seems this

Hello everyone, I am currently trying to debug a TMS320VC33 DSP target (my own design) board with the help of the XDS510PP (Plus) emulator and Code Composer (version 4.10.36). I have downloaded the relevant drivers from the Spectrum Digital website and have established communications between the XDS510PP emulator and the target board, i.e. I can load and step through code as expected. My pro...

I am wondering what are the most up to date development tools for the TMS320VC33 chip. I have Code Composer 4.10.37 (not Studio) I have the TMS320VC33 DSK I have a Parallel port XDS510 (used, in the mail on the way). I cannot load most programs through the DSK software (crashes) so have been using the code composer simulator, which is at its end of life because I need to use exter...

I am interested in using an industrial temperature range version of the TMS320VC33. The data sheet shows this on page 18 in the PGEA version. But I can't find any mention of this version on the TI web site or at the vendors. Does anyone know if and/or when an industrial version will

I am writing a simple program to test the serial port. (testing this for three days now, headache!) On the TMS320VC33. The code sets the I/O to output mode and turns them on. Then it shuts off all interrupts. After this it sets up the serial port for a transmit. I want the DSP to generate the FSX, and CLKX. I have tried many iterations of this code and settings of these registers but every...

Hello everyone, I have designed board based on TMS320VC33 DSP.I have faced some problems when running the board.System consist of flash memory access time of 70ns ,reset IC to proper start up and two regulator one of them is used to get3.3V from 5V supply and other is used to get 1.8V from 3.3V regulator output.Schottky diode is used between 3.3V and 1.8V supply voltages. First of all I tri...

hi, i'm a newbie with tms320vc33 dsk , and i would like to know : 1) is it possible for me to alternate between assembly language and C language within a same source code. if yes, how? 2) the software included ( im using version 2.02) has up to 20 application files (dsk3a, dsk3d, dsk3win, dsk3osc, to name a few). so far, i'm only using DSK3DW, which is stated as the debugger. what are the ot...

hello, i am working on TMS320VC33 UNIVERSITY DSK KIT. i am trying to send the real time data on parallel port which is coming from AIC PCM 3003. I have written a code in assembly. In that code i just directly write the data on parallel port which is in serial port receive register. Byte wise data is transferred on parallel port. i receive that data on system and convert that D...

Hi, I am new to this platform. I am using the tms320vc33. I am using code composer version.4.10.36 I have written an inialization code in (C and asm) for dsp. When I startup, the cpu registers are showing some default values and not zero. If I start to trace with these values, at the end of some function calls the trace goes to some unspecified location. But if I make the cpu regist...

Hi, I am using TMS320VC33 in MCBL mode.But till now we haven't done any boot loader programs, as we are in the initial stages of programming.We are simply writing some code for adc, dac etc for testing purposes.Initially it was fine. But nowadays we find some kind of degradation in the performance of DSP in the sense that,after we run the program twice or thrice the dsp stops responding.hard...

I have a system running that uses the Serial Port interrupt. It is the only interrupt enabled in the system. All processes are launched from the interrupt service routine. There are 4 interrupts spaced about 2.5 usec apart, followed by 10 usec period of no interrupt. Thus we have about 200,000 interrupts/sec. The ISR itself, with overhead for call and exit, has a worst case execution time of ...
