WebJul 8, 2024 · We have a custom board based on a STM32G483 MCU (Cortex M4). We use the SysTick as a reference for software timers. The SysTick reload register is set to 0x00FFFFFF so as to have the fewest interrupts. The SysTick is clocked with the CPU clock at 128MHz, which means there is a SysTick interrupt every 131ms or so. WebCortex-M Generic User Guides Clear Interrupt Target State. Clears the interrupt target field in the non-secure NVIC when in secure state. Parameters [in] IRQn External interrupt number. Value cannot be negative. Returns 0 if interrupt is assigned to Secure 1 if interrupt is assigned to Non Secure Remarks Only available for Armv8-M in secure state.

Ditch the Cortex-A8 method. This is the correct way to do it for most Cortex-M based microcontrollers (do not use SysTick!): Set up a timer, which runs at the same speed as the CPU. Do not attach an interrupt to the timer. Poll the timer value by using a single LDR instruction before you start your measuring. lampara 3w 12vWebMar 17, 2015 · Stopping SysTick when entering Deep Sleep is implementation defined and up to the silicon vendor. From the Cortex-M4 Devices Guide: Some implementations stop all the processor clock signals during deep sleep mode. If this happens, the SysTick counter stops.
