WebApr 11, 2016 · 1. Declare "volatile int count = 0;" outside of your main and interrupt routine to make it file scope. – Scott Seidman. Apr 11, 2016 at 14:43. 2. By the way, make sure … WebJan 10, 2024 · Nick, There are 2 parameters in play with the interrupts on the C2000 MCU; I think it will help to clarify these a bit: 1)Priority - As you mentioned all ISRs in the PIE have a fixed priority both outside their group; i.e. group1 interrupt sources have higher priority than group 2 ansd so on and within a group ISR 1.1 has higher priority than ISR1.2, and so on. tidal works
Counting pulses with interrupts - Arduino Forum
WebRising edge interrupts at PD7 call a function that saves the timer value first in a static variable, then clear the timer and save the read value in a static uint32_t [4096] buffer, when the buffer is full I deactivate the interrupts and the process is finished. In a later stage, I send the stored values through the LPUART1 (that is connected ... Web1 day ago · The first parameter to attachInterrupt () is an interrupt number. Normally you should use digitalPinToInterrupt (pin) to translate the actual digital pin to the specific … WebFeb 2, 2024 · /proc/softirq is softirq stats. Is /proc/interrupt both hard and soft interrupts or hard only?. I want to measure the rate of hard and soft irq's per second roughly using watch -n 1 grep 'foo' /proc/softirq and watch -n 1 grep 'bar' /proc/interrupt so I can compare the rate of hardware interrupt increase to software interrupt.. I'm wondering if I need to subtract … tidal workflow automation
