Hello, I´m doing a migration from 5410A to 5416 and I´m having problems when returning from interrupt service rutines. I don´t build the project with the -mf option (i´m using near calls as default) because there are several vocoder funtions that we don´t want to change so I want to keep them in the same page and call them as near. For the rest of the program that is in another memory ...

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! 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

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

Hi, i was wondering if anyone could help me. I have modified the timer interrupt example that came with code composer studio, so that the prd register that sets the timer period can be modified by certain variables in the task function. Also i have changed the set up of the ISR so th

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

Hello All, I am using c5409 on my target board. I am not able to configure interrupts for MCBSP. I used the vectors.asm and added the ISR name in RINT0, XINT0 labels. In my command file I have mapped the vectors to 0x7f80. Emulators gives memory map error when I try to l

Dear Sirs/Madams, I am using the 5402 Dsk. I am using the Mcbsp0 and I want that when the port receives a data, an interrupt will be executed. In order to do that, I write firstly: IMR=0x0010 to enable Brint0; IFR=0x3FFF to disable all interrupts; asm(" RSBX INTM&quo

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
