Hi, I have one very simple question. I hope some one will clearify my doubts. The range of frequencies covered in the output record from the FFT is 0 to 1/2 the sample rate of the acquired data record. For example, a sample rate of 20 MS/s (megasamples per second) would give an FFT range of 0 to 10 MHz. Does it mean that I can only see proper FFT peak of the signal with maximum f...

Dear guys, I meet a problem when using the C6455 chip to run a Gigabit network project (based on ndk 2.0). For some reason, I change the DSP/BIOS CLK to 100us(0.1ms) and set NDK prdNdk period 1000 ticks (0.1*1000=100ms), while in helloWorld.pjt example, I see the DSP/BIOS CLK is 1ms and prdNdk period is 100 ticks. Does this matter? The C6455 chip will process one image about every 25ms. ...

Hi guys My project is ?control a dc motor by DSP TMS320C6713B DSK. First of all, I just need to know that how the A/D & D/A & PWM output &?Of this starter kit works? Cuz I didn?t find anything about ?how to work with these stuffs" in its technical Ref. Do I have to use an external A/D & D/A & ?, or the kit itself has them??? (for instance ADS 8382) but the most important thing is

Hi, I am using a custom C6713B board. I want to boot from Flash. And so I have read the TI Doc SPRA999A to create a secondary bootloader. I am using the hex conversion utility. And have a couple of questions. 1) If I am using a 512k x 8 Flash device. What do I specify in the options of the hex conversion utility for -memwidth and -romwidth ? 2) If I specify -memwidth=32 (sinc...

Hi, I want to create a secondary bootloader for C6713 DSP. I am using the SPRA999A document form TI for this purpose. The document suggests to create and link the copy table as follows .text : load = FLASH_REST, run = IRAM, table(BINIT) .const : load = FLASH_REST, run = IRAM, table(BINIT) I have used the same in my linker command file.

Hi I am using C6713 and want to interface a UART. Doing so by using McBSP as GPIO. I have taken the code from the TI's SPRA633C document that describes how to use McBSP as a soft UART in GPIO mode. To test the code and verify if I am receiving correctly, I just put the code inside a while(1) loop inside main() as follows voide main(){ ----- ------ while (1){ Ua...
