All, I am using the EDMA to output waveforms to a 4 channel D/A. I use Timer 1 to synchronize the outputs and initiate each transfer. I would NEVER have gotten this far without the help of my good friend Maur Gaganjot of TI and he actually came up with the scheme I am trying t

Hi Mayank, first of all, which target processor do you use? I'm using a C6416, maybe the configuration for C62x and C67x processors is different from mine, but I hope this will help you though: There are two different types of starting an EDMA transfer, event tr

Hi I'm working on the implementation of a TDM driver with 6416 processor. The McBSP is used to transfer data through EDMA. The clock for McBSP is provided by an external device. Due to some lack in synchronisation between McBSP and EDMA, the data appears shifted and appears in the next channel. The data for channel 0 is in channel 1, data for channel 1 is in channel 2 and so on. A ...

hello everyone! I'm now doing a project focus on transmission of data thru mcbsp that controlled by edma.the project is based on the 'app_dsk' demo.in the demo project,it uses mcbsp2 in both receiving and transmitting,in my project I just use mcbsp0 to transmit,no receiving,the data for transmission is prepared in the program.I just configure the registers of mcbsp0 and edma as required,mcbsp...

hi all I am using DSK6711 I got a problem If the EDMA is configured to tranfer 16-bit elements how will the McBSP handle if it is configured to tranfer only 8-bit elements. I mean how will the mismatch between the EDMA and McBSP element length handled DXR is 32-bi

Hi, I use EDMA to transfer data from a int. buffer to ext. RAM and vice versa. Pointer from a IRQ routine have access to the int. buffer too. When EDMA ptr and IRQ ptr are 16 samples (512 bit) apart all works fine. Unfortunately with 16 samples the buffer is to small for all pointers. With 8 samples (256 bit) apart I get wrong data. The only reason for those errors I can think of is ...

Hi, I have a custom DM642 board. I am using the Video Port 2 for Video In. McASP0 for audio and McBSP1 configured as UART. 1).McASP0 +EDMA ( Ch 12 , Ch 13)is configured for audio transmit and receive. The code has been taken from the "echo" Project under the evmDM642 examples for audio and modified. 2). McBSP1 + EDMA( Ch14 , Ch15) is configured as UART for RS485 TX & RX. The problem ...

Hi! In spru578c chapter 8.4 there is a description of how to change the HPI EDMA priority. The description is rather involved and for a newbie at TI EDMA not that easy to implement. There really should be a CSL function for this. Is there anyone who has the C-code for doing this? Thanks in advance. /HUGO.

Hello ! Is there some TI resource describing the throughput of EDMA transfers ? It would be great if there is a definitive way to choose between two types of transfers, to get the same effect. For e.g. when I tried a 2D to 1D transfer to move two columns of 16-

Dear All, I am new to DSPs, so this might seem like an elementary question to some! I am developing on a C6711 DSP, using code composer (v2.20) and making use of the CSL. I have created a simple EDMA which copies a 1D array to a single memory location (an LED bank

Hi all ! I am having trouble using the L2 config register in the C6711 DSK. I try to EDMA data from SDRAM into L2, and do some processing on it. If I configure 16K of L2 to be Cache, and enable caching for the SDRAM (MAR0 = 1), the EDMA does not do the correct tr

Hi all, I want to interrupt the EDMA each time a certain buffer is filled by the RTDX: 1) is there an event for that? 2) if not and it has to be done manually, does the command EDMA_setChannel() triggers the edmaHwi function? because, I put some test lines in the beginnin

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 ...
