• Cortex M4 (LPC4370): how do I detect ADC threshold crossing while moving data in a DMA driven double buffer?

    Hi to you all,

    I'm currently working on a project involving the LPC-Link2 as a eval. board for it's LPC4370 (for a complete explanation see this question).
    What I'm trying to do is:

    • Continuously sample external analog signal (using on-board…
  • Cortex-M4 interrupt priority dynamically change while in ISR

    Hello,

    I am using STM32F407ZGT6 Cortex-M4 microcontroller. I am interested in changing the priority of a certain interrupt while servicing the same interrupt. Is that possible?

    More elaborately, lets say I have an interrupt which has a priority of 4. The…

  • Cortex-M4 interrupts behaviour when same interrupt vector has multiple interrupts

    Hello,


    I am using STM32F407ZGT6 Cortex-M4 microcontroller. This controller has same interrupt vector for 5 external interrupts i.e., NVIC (EXTI9_5) for EXTI5, EXTI6, EXTI7, EXTI8 and EXTI9 interrupts. They all have the same ISR EXTI9_5_IRQHandler interrupt…
