Hello! I've got a small programm that lets a LED blink on my DSP. It's a TMS320F2812 on a ezDSP F2812 board. The program didn't seem to work until I once disconnected and reconnected power supply. I also changed one jumper on the board to another position (where the led is always on) and back to the position where the LED is programmable by the XF-pin. Then it suddenly worked and blinked....

Hi Everyone I have two implementations of the F281x family, one is a 2811 on a board that we thought we'd laid out exactly according to TI's recommendations, the other a 2812 EzDSP board. On both of these we see a lot of dispersion (about 10 counts) when sampling a constant input signal. On the EzDSP the input is provided by a potential divider between the analog VDD supply the analogue gr...

Hi there, I'm reading a paper at the moment which refers to an "A-DSP", and also refers to "analog-to-digital signal processing circuit". What exactly is this? Is it simply a ADC or is it a ADC and DSP board in one? This device intefaces to a PC via an IO-board and its not clear if signal processing takes place on the A-DSP or the PC. Can anyone enlighten me? Regards, Cathal.
