This code runs in an interrupt (a DMA irq) TC = (*(_timer_10ms) == #0) if(TC) goto hold_10ms *(_timer_10ms) -= #1 In non-interrupt time I check for it being at 0, do some stuff, and reset it to 12. if( timer_10ms == 0 ) { inc_clock(

Hi everybody, I'm trying to realise an interrupt generated by the timer but unfortunately the code lines included in the interrupt program (i hope this is clear enough)are never done. I read the documentation about the timer and also about interrupts, but i don't s

Hi all, I am new in DSP development. From the Host point of view: Is there an usual method to know if the DSP is out of reset or in regular stage when the host receive a Host Interrupt (HINT)? Thanks, Eli.

Hello All. A peculiar thing just happened to me (with a new DSK 5402). What I did, was to read McBSP0 with DMA using auto-initialize. The idea is to fill a buffer, and then go on to the next one. The interrupt routine is supposed to alter the global registers, so the

Hello, I'm doing a university project with the 5416DSK. In this project I'm using external interrupt pins INT0 and INT1. I've set up the hardware interrupt using the configuration tool of CCS. The HWI calls a function which lights up a LED on the DSK. Although I would like it

I have made a delay function where I use Timer 1. It seems to work fine until the first timer underflow. I can see that the Timer1 flag is set in the interrupt flag register, but the flag is not reset when the interrupt is taken. The other interrupts I use in my program resets their

Got my interrupts going. I can now read data from the AD50 every time a receiver interrupt occurs. As Dave Helsley suggested, the problem I had was that the DRR register was being overrun because I was not reading it quick enough. If DRR has not been since the last RBR to DRR copy, a

I have a problem with interrupts on the C5402 DSK. I use the IDLE 1 instruction to wait until a BRINT1 interrupt occurs from the AD50 codec, indicated by IFR=400h. When this occurs, the program does not jump to vector table and hence to the ISR, instead it loops around and waits for

I'm having troubles getting the DMA and the BSP to syncronize with interrupts. In general I cannot get the DMA to fire an interrupt after a block transfer is complete. The interrupts are enabled in the IMR. I can enter my interrupt with the MCBSP running alone. I can also run my DMA in no sync mode. I can conduct one block transfer based on t

Hi all, I'm a student and I've to develop a FIR filter with Interrupt using c5402 DSK. I use ccs 2.1. For first I start from a perfectly working Hello World(I think you say WOW!!! :D ). My Idea is to create an interrupt-ed Hello World and then start the implementation of the filter. The problem is that when I create and add a .cdb file with the configuration of Timer and HWI Service Routine M...

I'm trying to set up the bsp for an 8-bit, n-word frame transfer syncronized with the frame sync signal. At the end of the n-word frame I want the interrupt to fire. Ive set up an external pin to toggle inside the interrupt. It continues to fire but randomly and not every frame. Below is my register setup. MCBSP_Config bspConfig = { MCBSP_SPCR1_RMK (

Dear All ! It is written in technical reference that the default of the IPTR Interrupt vector pointer is FF80h. When I performing reset - I recieve 7F80 instead. Why is that ? Thanks in advance !
