Hi All I don't have a lot of experience handling electrostatically sensitive equipment. I've recently purchased a TI DSK (C6713) but haven't plugged it in yet. I was worried about the ESD and wanted to know what would be the cheapest/easiest way of ensuring I don't cause any damage to the kit. Would a wrist band suffice? Also, the leaflet in the kit says that it is intended for use in a "la...

Hi, I'm a student of communication engineering, with interest in software defined radio. Can you tell me what are good references for learning to implement communication algorithms on Digital Signal Processors? My univ has c6416 and c6713 so have the facility to work on them. From posts in this group I see that most people are in this field, so perhaps you can give me good tips to develop my...

I'm running way too slow, but I know I've done a few things inefficiently on in my C program. 1) I ran out of IRAM memory so I moved all my variables to ERAM.

Hello all, I'm currently evaluating some DSPs for a soon to come project which will include the development of a hardware platform and the port of a software currently running on Mac and PC platforms. I've written a non optimized piece of code (in C++) and ran it with the simulators provided by Texas and Analog. I got about 74000 cycles for the 6713 and 32000 for the 21262. I don't want to...

Hello, I'm trying to statically allocate a matrix in an external SDRAM. I'm using the C6713 processor. when I insert the following lines into my code: #pragma DATA_SECTION(a, ".userdef"); float a[M][M]; with M as big as 375 and userdef defined as SDRAM in a separate cmd-file, everything seems to be fine for the start address of the matrix.

Folks Re: ebay item 8749091151 I received this last week in the UK from Hong Kong. It took only three days to arrive! Early indications are that it seems to work fine on the C6713 DSK with CCS 3.1, although it seems a bit slower than the embedded JTAG DSK emulator. Still, at less than 20% of the cost of the Spectrum Digital USB JTAG Emulator, it's a bargain. Regards, Howard ...
