Forum Post: How do I setup the GPIO pins and where are they physically on the PADK c6727?

manferd

I've been trying to write a simple program for the PADK Professional Audio Development Kit C6727 DSP that will turn on/off an LED using the HAS pin setup as a GPIO pin according to the state of one of the push buttons, but I can't seem to get it right. Here is what I have: CSL_UhpiHandle hUhpi...

Forum Post: EDMA performance impact when breaking up a large transfer (1D) into smaller transfers (2DS/1DD or 1DS/2DD,array synchronized (FS=0))

Steffen Martin

Hello Community, I've run into issues when transferring large blocks of data (e.g. 4 kBytes) across the EMIF using the EDMA engine (lock out of other same priority transfers, clogging up the EMIF) which is why I decided to break it up into smaller transfers. I created respective EDMA configurations...

Hello We are using the TLV320AIC320K in the following configuration inside are board I also find an Evaluation board without a driver for MCBSP we are using a cascade configuration of smart TDM. The purpose of using MCBSP for configuration instead the I2C is to overcome some codec initialization...

Forum Post: dsplib functions disable interrupts.

deckard26354

Greetings. I noticed that an IRQ I have to handle MCASP rx events was encountering ROVERN errors on a C6727. After some digging I found that DSPF_sp_fftSPxSP was the culprit. I looked into the given assembler source in dsp67x_src with dsplib and found that DSPF_sp_fftSPxSP disables interrupts...

Forum Post: Re: Receiving serial data by McBSP/McASP port by EDMA took a long time to get to the EDMA channel interrupt service routine! Why???

CMA

Hi RandyP, I finally found the interrupt service time dealy problem to be due to placing the interrupt service table in an external RAM before properly setting up the EMIF controllers. So this problem is solved now. Now I have a different problem though. It's as follows: I want to burn my...

Dear fellow engineers, I hope I can get some help from here instead ... I would really appreciate it! I'm trying to make my 225MHz C6713B board receive serial data through the McASP1, McBSP0 and McBSP1 ports by EDMA. Upon any receive event, I would like to be notified by an interrupt service...

Hello, My question is a little naive and likely that I am missing a point, but still: I have been profiling the Vector Dot Product function using the benchmark DSPF_sp_dotprod() source from C67x DSP Library and DSP_dotprod() source (intrinsic C implementation) from C64x DSP Library respectively...

Hi, I have to switch to use the new TI DSP chip C6713 because the old C31 is out of production and I can't even find them from surplus stores any more. I'm running the C6713 at 200MHz now, whereas I was running the C31 at just 80MHz before. Nevertheless, I converted my old C31 program...
