Hi, I know I can use a #pragma to specify a single memory allocation that I want to locate using a cmd file w/ CCS 3.3. Can I indicate in the cmd file to put all memory allocated into a specific memory block? Regards, Joe ?

Hi, I'm fairly new to DSPs and TI's development tools. I've inherited a project that I'm having a problem with an ILLEGAL_ISR. I'm using CCS 3.3 (sp 10)?w/ DSP/BIOS 5_32_04 and code gen tools 5.0.2. The project I inherited runs on a 'F2812 (compiled w/ older tools and CCS). My job is to triple the calculations and get it?to run on new h/w based on the F28335. I have a h/w interrupt that read...

Dear all, I am converting the ADC values into IQ number for the purpose of processing it further in reduced computation time. My global IQ is 19. The following line works for me, but it took several hundred cycles for execution in F2812 eZDSP. Adc1[ConversionCount] = _IQ(AdcRegs. ADCRESULTO > > 4); Where, _iq Adc1[ConversionCount]; I need to do this as fast as I can, to tackle with o

hi, i'm new to ezdspf2812, i have a project using ezdsp2812 to control a plant. at the first step, i'm planing to use this board as a controller to control a plant simulation on matlab, but i don't know how to acquire the input references and feed back data from matlab, and to process it as the input for the plant simulation. thx for assistance regard alrianes bachnas OMAP35x EVM...

Hi, I am using Simulink Target for TI C2000 to program an F2812 eZdsp board and a TLV5638 DAC to implement digital controllers. However, initially I am just trying to sample/convert a signal through the ADC, SPI, DAC and display it on the scope. I have constructed TIC2000 block diagrams to do this, but I don't know how to incorporate the DAC initialization & control bits in the C2000 diagr...

Hi all, I want to confirm whether the following linker file is correct for handling IQmath in RAM.Because all my computation values look very starnge to me.Can any one of you reply me? Its urgent. If it is wrong then please tell me the correction. Many thanks MEMORY { PAGE 0 : /* For this example, H0 is split between PAGE 0 and PAGE 1 */ /* BEGIN is used for the "boot to HO" bootlo...

Hi, I wanted to know whether do we really need to have a SEU check for F2808 based application running out of RAM? If yes no then why?

Hi, I'm looking for a little clarification on how the ADC voltage reference is used on the C28xxx processors. I've used AVRs, ARM7s, and Cortex-M3s in the past and conversion from digital counts to analog voltage was always something like: Vin =3D ADCvalue/4096 * Vref Where the input range is Vagnd =96 Vref. However, on the C28xxx according to the ADC datasheet, the equation seems t=...

Hi friends, I am working with F2812 processor and I want to generate .hex file by hex-conversion utility for flash programming. I generated .hex successfully by using command line option. But I want to generate .hex file by using "command file" option i.e for example "hex2000 hexutil.cmd". I followed the steps given in the datasheet Assembly Language Tools for C28x processo...

HI, Anybody knows how to disable external interrupt XINT13 of F2812 chip. I read the F2812 INT doc, but it seems that we only can select INT13 interrupt source- external PIN or Timer1. But we can not disable it. Thanks LI Bing OMAP35x EVM jump-starts low-power apps The modular and extensible OMAP35x Evaluation Module (EVM) enables developers to start building applications based o...
