Hi,
I'm working on a Cortex-M4 (STM32F429-DISCO) with the Ravenscar profile, using Ada language.
What I want to do is to trigger a software interrupt from a procedure in a task. This in order to have
the same algorithm, which governs the interrupt…
I don't want to setup the vector table for all my external interrupts. For instance I only need the timer4 IRQhandler at IRQn 30. How can I make an offset in the table? Is this necessary?
Hi,
I want to use the wfi instruction in my code. I'm sending a command to a module and wait for the reply.
I have configured UART communication with the module. Will it be good to use wfi() instruction? I know that it will turn the cpu to power down…
How long does it take to wake up from from WFI once an interrupt occurs?
What system parameters does the answer depend on?
What's turned off in the CPU (and elsewhere) while WFI is underway?
I'm using NXP i.MXRT1050 (Cortex M7) and I'm experiencing…
Hi all,
I 'm an embedded software engineer and I'm currently working on a nRF51822 target which is a ARM m0. I want to design a fault logger to track errors in our code even it a debugger is not attached to the device at the moment of the fault.…
This is a very common question.

Dears:
I download the IP of cortex-M0 on the arm website, but there are no DAP (debug access port) and WIC(wakeup interrupt controller) code in it. is there anyone who knows where i can download the IP? Thanks very much!
Hi,
I am using Cortex-M0 DesignStart Pro. When I simulation intrrupt_demo test case, I found that IRQ[31:0] always 0, Is this correct?
I saw the document , the interrupt_demo is Demonstration of interrupt features, but if no interrupt signal input…
Hi,
I am using Nuvoton M058LBN. In my code, my while 1 there are some functions which should run continuously. But it was getting reseted . So for checking I printed some statement which is getting printed 10 times after which it stops printing and restarts…
Cannot configure interupts of TIM6 on stm32f103 board
Does my NVIC configuration wrong?
Code:
@ stm32f103 timer & interrupt test by laper_s (from 2019-02-02) .thumb .cpu cortex-m3 .syntax unified .word 0x20005000 .word start + 1 b start…
The queue for the processors interrupt context-m supports how many pending interruptions?
Complementing please send me information where I can read more details about it.
Thank you.
We know that a Cortex-M0 or any other Cortex-M may have fewer interruptions implemented the architecture defined in the standard, so we can not use interrupts implemented as software interrupts by manipulating the registers SETENA / ClrEnable and SetPend…
Arm Cortex-M processors offer very versatile interrupt priority management, but unfortunately, the multiple priority numbering conventions used in managing the interrupt priorities are often counter-intuitive, inconsistent, and confusing, which can lead…
ARM Cortex-M based microcontrollers are becoming the defacto standard for the next generation of low power control applications.This paper looks at the various criteria to be considered when selecting a processor for low power control applications, and…
