Hello Folk, I am newbie to DSP Architecture. Actually, I am trying to convert analog voltage in digital by means of a Software SOC as well as ADC subroutine (ADCINT_ISR). For this I have configured F2812 for cascaded sequencial mode. I have selected A0 channel for Analog Input. And all further details is shown on code. I don't know from where i am getting wrong. May be Interrupt Initi...

Dear All, I'm facing a problem with interfacing Serial EEPROM with TMS320F2806 processor. The device that i'm using (93C66B microchip serial EEPROM) is connected to the SPI interface of the processor. I'm able to write data into the EEPROM. While trying to read the same data using my DSP, I'm facing the problem. The voltage level of the Data Out signal from the EEPROM varies from 0V (log...

Hi, I?m working on the TI TMS320F2812 DSP. My program is activated by external interrupt xint2 and basically receives 2 variables from SCI, uses the ADC to adquire 3 DC voltages from potentiometers, and uses those 5 variables to make some calculations using IQmath and deliver the results through the digital I/O. Due to noise present at the potentiometers, there is a variation in the d...

Hi All, I am facing a prob. After programming Flash, It is not executing program after a power on reset. But start working when I started CCS & giving RUN command. So it is not working as a standalone system. Used eZdspTMS320F2812 & JTAG Flash utility. I think some mistake in initialization. If any body have any idea pl. help. Biswarup

hi everybody! im currently working with an eZdsp TMS320F2812 board (from Spectrum Digital). it was working fine the other day but when I tried to use it today with the Code Composer Studio DSL (v.2.12), CCS would freeze at startup with the following error message: "Failed Software Reset: Processor reset or no power to target I/Os " the board is powered (indicated by the LEDs) and it...

Hi, I'm using CCS 3.1 and a Signum JTAGJet C2000 for a F2801. Code download into flash or ram, debugging, etc. works fine. If I load the code into flash using the Flash Programmer Utility included in CCS I can debug it via JTAG. But the DSP won't execute any program if I remove the JTAG header and pull the reset line. Are there any options I have to set for stand-alone operation? T...

Hi Some of my programs run correctly only when I load them into specific locations (external RAM/ internal memory). They give wrong results at the other locations. The program is correct as I get the correct result when loading at some other location. I identify the problem to be something related to the command file or some settings to be made in Code Composer Studio. The results when they ...

Hello, I am trying to interface a serial device (GPS receiver) with the f2812. The device gives the serial signal at +/- 5v as it should but the dsp requires all serial signals to be between 0 and 3.3v . Is there a simple circuit that can be used for this or some type of conversion cable? Thanks for any advice! Kevin
