Dear all I have a problem with DSPlib for tms320VC5416 chip. I use POWER function from dsplib library to calculate the sum of sqrs of an input array. It was ok until I add ST-BUS support to the project. I get input data from ulaw codecs with sampling rate of 8000 sample per second. Because ST-BUS consists of 32 channels, it interrupts my chip 256000 times in a second. But adding ST-BU...

Hello, I am having trouble getting CCS to initialize a target upon startup. I am getting the error shown below. The processor is a TMS320VC5416. I am running CCS 2.20.00.I am using a Spectrum Digital XDS510-USB emulator. I have successfully detected the JTAG device in the scan chain by doing an emulator test in SDConfig. Probing the board reveals that the processor is receiving power. Searching fo...


spra836: I2c implementation on DSP

Hi all, I tried to use source code available in spra836 document (i2c bus on mcbsp port) on my TMS320c5416 DSK. In this documents I understood that all funtions (init_gpio,i2c_init etc...) are C callable. Someone tried to call these function in a simple C source code ? I tried it, but when I call for example init_gpio, the function seems works good, but at the exit I don't eturn at the correct...

I don't know where you get this info, but it's not correct. The C5441 data sheet clearly indicates that each core has 4


PLLCOUNT problem

I'm having some trouble on configuring my DSP C5402 to operate at 100 MHz, through the CLKMD register. The PLLCOUNT bits are calculated through the formula and the graph present in the image below. However, in this graph from the 320C54x family, there is no 'lockup time' for a CLOCKOUT of 100 MHz. But the C5402 CAN operate at 100 MHz. Pretty weird, huh? Wich value of 'lockup time' should I choos...

Hi all, I'm a student and I've to develop a FIR filter with Interrupt using c5402 DSK. I use ccs 2.1. For first I start from a perfectly working Hello World(I think you say WOW!!! :D ). My Idea is to create an interrupt-ed Hello World and then start the implementation of the filter. The problem is that when I create and add a .cdb file with the configuration of Timer and HWI Service Routine M...

Hi, I am using PIC18F97J60 to boot 5416 using MCBSP0. I have built my boottable using -v548 assembler option and I am sending this boottable starting from word 0x10AA after resetting the dsp and waiting for XF pin to go low. I worked on this issue so much and read all the documents including the bootloader document(spra602) supplied by ti. I think the documentation is insufficient. Can you tell h...

Hello everyone. I have a TI DSP development kit (TMS320C54x) and Code Composer Studio v. 3.3. I am trying to recompile the demo program they provided. Its called DM6437_demo.out (or something similar). There is a .out file that I can load onto the chip and it will set up a server for communication via Ethernet, stream a video from the computer, decode it on the chip and output it. A DM...
