Hi All, I am using the DSK6455 which includes two MCBSP port and these two MCBSP port of 6455 can be use as a SPI interface. In my system I use both MCBSP port to interface with ADC/DAC so there is no free MCBSP port. As I need another port to interface with a MCU which require a data rate at about 30Mb/s, so I decided to use the SPI interface. Since there is no free MCBSP port in my sys...

Group, sorry for the elementary question: I am trying to set up my board to generate an interrupt from the UHPI_HAS input pin on the C6727 DSP. Setting up the UHPI registers seems strait forward as outlined in the UHPI ref document. (spru719.pdf) *(Uint32)GPIOEN = 0x00000004; // configure UHPI_HAS pin as a GPIO pin *(Uint32)GPIODIR2 = 0x00000000; // UHPI_HAS pin is input *(U...

Hello everyone, I am using EDMA channels in TIC6713 and i am using CPU triggered EDMA's and some GPIO triggered EDMA. And there are sometimes when I use EDMA channels with different TCC number, and hooked the callback function hooked to this tcc number using inthook(tccnum,function). Right now the the function is called myedmaisr and then I com


Generate a CONVST signal to ADS8556 using a GPIO pin from C6713

Hi, I am using a precision ADC ADS8556 (TI's document SBAS404A) on my board interfaced to a C6713 DSP through a McASP. I have the GPIO5/EXT_INT5 pin of the DSP connected to the CONVST_x pins of the ADS8556. The CONVST_x pin has to be synchronized with the Frame-sync from the McASP. (please look at page 14 of SBAS404A ADC datasheet for the serial interface timing). Can I synchronize...

Dear All, I need some advice on the data transfer from the C3088 cmos camera to the 8MB SDRAM of the C6713 board EMIF. Firstly can we use the GPIO to transfer pixels to RAM or do we need to use the EMIF for DMA allocation? We need to transfer the data pixel by pixel, not frame by frame, since we have 16 YUV pins from the camera going into the board as 16 external interrupts. Can you tell...

I am using TMS320C6713 DSP in my project. 1) I want to write single fix byte periodically to EMIF CE3 by using timer interrupt. 2) I want to read single fix byte from EMIF CE3 at external gpio interrupt. Read and write strobe widths are 600nsec. i think processor stalls at read and write. In order to make procedure more efficient i tried to use EDMA because EDMA can read and write from ...
