Good day. 1)Just like to find out whether anyone try to hand code in assembly for C5402 DSK codec example? examples in DSK are C coded and clueless about the memory mapping, interrupt setting etc. 2) Tried to implement asm code for codec... setup McBSP1 and DMA ch

Good day. Say DMA channel 2 is configured to do a block transfer of one frame with 256 elements. When data is received via MsBSP1 (DRR11), REVT will caused a DMA channel 2 interrupt. Now, my understanding till now is that DMA will collect 256 data and send all 256 data in a bl

Hi, I have some problems while using the CFFT and CIFFT functions in the DSPLIB. It works well with the C5402 DSK board but when I uses that function on my actual prototype board, the interrupt stops working after the first loop. I can't take in new input with out that interrup

Hi it's me again. I have still problems with Interrupts on the C5402 DSK Board. I'm not able to fix my interrupt problem. I found the TI documentation very horrible. There are no source code examples that show how external interrupts are realised in C. I fou

Hi there, I'm just implementing a DMA transfer in ABU Mode from the McBSP to internal Memory. Everything works correct, but - when I use DMA Channel 0 I was never able to get an IR from the DMA. I have tried the same (with the same code) for DMA chann

I have written a small piece of assembly code, that sets up the c5402 DMA channel 1 to transfer data from DSP memory to McBSP0. Each transfer is synchronised by a Timer0 interrupt (at a 48kHz rate), and everything works fine. However, when trying to use the same code on a c541

Hi all, what do you think on the following synchronisation problem: - two DSP/BIOS task objects (TSK_A and TSK_B) have the same priority (e.g. Priority 1) - TSK_A is running (its execution state: TSK_RUNNING) - TSK_B is ready (its execution state: TSK_READY) - interrupt o

Hi, As the C54x DSP's have both hardware and software interrupts, i would like to know why do we need to interrupt the DSP by software.(Because instead of software interrupts we can use JUMP instruction). When do the need of software interrupts arises.? Also I would like to kno

Hi, I posted a message a few weeks ago about this problem but I am still having trouble with a sampling routine being interrupted causing it to miss samples. My setup is: programmed in CCS, using the onboard codec to sample from the mic port, using RTDX to transfe

hi there! im using the TMS230C5402 DSK my goal is to process a large amount of audio sampels which comes from the McBSP. i decided to use the DMA cause the memory is not big enough. i have managed to use the dma to seperate the input to frames and i enabled the interrupt

I'm working on using McBSP1 on a 5416 in clock stop mode as a SPI master. I have successfully set it up so that it will transmit a block of bytes using DMA #2, and generate an interrupt when the block is finished. Now I'm trying to use 2 DMA channels, one for transmit (to keep

Hi I am using "External Interrupt 3" as a DMA synchronization event in a C5416 DSP. The source and destination addresses are in internal data memory and I/O space respectively. The problem is that the first event initiates element transfers and the DMA channel
