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...

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...

Hi all, I fed 2V and 1V DC signals to ADCIN0 and ADCIN1 respectively and ran my program in F2812 DSP, it didn't work as i have expected. The thing is I observed ADCRESULT0 as 0XFFF0 and ADCRESULT1 as 0xFFF0 in watch window.I have given ADC VREFLO to gnd and the two ADC inputs gnd to the analog ground. Moreover, I have also observed the equivalent voltage after the conversion of digital input by...

Hi, I have defined few constants like #define conversion 0.534 #define x 25 #define format 666.66667 If i run my program and see the values of the variables it was wrong, hence it gave _IQ(conversion) in watch window to view the value, it shows that 'identifier not found : conversion' in the value column of watch window. Why it is? Then how can i ensure that, it has taken defined valu...
