Interrupts

Other Parts Discussed in Thread: OMAP-L138

Hi, I want to implement 2 interrupt for DSP and one of them occurred every 833 µs and one of them every 2000 µs in 1st one it will get data from AD (Analogue to Digital) and in 2nd one it will do some functions. How can I implement them? Is there any classified way for implement 2 or more interrupt? Any help thanks a lot.

    Keivan,

    Which device and development board are you using? 

    Are you asking how to implement the hardware, or software aspects of interrupts?  

    From software perspective, you would typically use something like DSP/BIOS to provide the APIs for interrupt servicing.  You can download DSP/BIOS on the OMAP-L138 product page on ti.com

    From hardware perspective, you can use an internal timer to generate an interrupt at a specified rate.  Also, your AD device can trigger an interrupt directly to the DSP via a general purpose input signal.

    Regards
