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.

I found that several guys had same problem with Code Composer Studio 3.3 and new ezDSP 28335 (missing floating point library). I saw that there are updates on TI's Web, but I could not download Code Generation Tools v5.0.2. TI's technical support couldn't realize why since I'm registered user of full featured CCS, than they tried to send it by e-mail, but this EXE file is about 16Mb and it could ...

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...

SCI as UART and FIFO on TMS320F2812

I'm trying to use SCI port on TMS320F2812 as UART with FIFO enabled. The idea of having FIFO is to reduce the interrupt burden for every character. If received characters are less than FIFO size and receive line is idle for a long time then those characters are stuck in FIFO. Processor won't get interrupt for those characters until FIFO gets full. > From my experience with different UART
