Hi all, I am using F2812 TI dsp. I want to write a value in a certain memory location. The value is"0x0003" its address is "0x00200D". I am not sure if there is a way to write that in C. If you can please tell me about the assembly code which should be used to perform such task and how to include it in a C code? Best regards, Bahaa _____________________________________ ...

Hi, I'm using a development board (F2808). I used the JTAG interface to load my program into Flash Memory (with the Flash plugin in CCS3.1). Everything works fine. I need to allocate a specific area into flash memory to save a table, for example. Thoses values will be modified during a calibration process (after having program the unit F2808) and the idea is to avoid loose them after "reset"...

Hi there, I want to connect the DSP with a LCD and a keypad. When switched on the user is asked about certain parameters, which he can feed into, using the keypad. The collected data has to be transmitted to the DSP and stored in the variables until a new input has been made. Does anyone know how I could implement that? Which Hardware could I use and which interface should I use for data t...

HI all, I am a new user of F2812 TI DSP. I read a previous posts form you recommending TI examples for beginners to trace. So I started with the CPU timer example v111. I built a code which toggles Pin0 on port A using timer 0 interrupt and use it as the main code in that project. Below is my code. #include "DSP281x_Device.h" // Prototype statements for functions found within this fil...

I'm trying to calculate FFT with C28x Fast Fourier Transforms Library (sprc081). The 1-st lamers qestion is why TI use narrow dynamic range - Q31 for calculating FFT (range: -1..1), how to work with it if math library doesn't suport it? Another problem is to get right result of fft calculating. At thirst I've tested fft with CFFT32_brev2 bit reversal utility and it works incorrect. CFFT3...
