WebJun 26, 2008 · Processor: STR750 (ARM7) Compiler: IAR I just saw a post asking about interrupt wrappers for the ARM7 so I thought I’d respond with this post. Since it doesn’t really answer his question, I’m making it a new thread. I’ve set up my interrupts to be normal functions running in Thumb mode.

WebWhen you only allow one character/interrupt and turns off interrupts between receive and processing, then your receive task must run with very high priority. When the receive task is allowed to process data in bursts, you can reduce the receive priority as long as all higher-prio tasks are guaranteed to leave leave some CPU time with a reasonable max interval. Webif there’s an interrupt event, process it. fetch the next instruction from memory. advance the instruction pointer. perform whatever that instruction says. rinse and repeat. So in a way, interrupts are nothing but lots of checking, done in hardware. At the start of every new instruction, the processor does the checking for us.

WebFeb 15, 2024 · As shown in the video, the Cortex-M interrupt entry loads the LR link register with a special value, such as 0xFFFF’FFF9, instead the actual return address. Later, when the ISR returns (e.g., via BX LR), the hardware recognizes the special LR value as an interrupt return and restores the CPU registers saved during the interrupt entry.
