DoganIbrahim, inPIC Microcontroller Projects in C (Second Edition), 2014 Interrupt Service Routines Aninterrupt service routineis recognized by the keywordinterrupt, followed by the name of the routine. An example is given below: void interrupt Myint(void) ...
Use UART Interrupt of Pic Microcontroller with Examples (PIC18F4550)
In C language, an interrupt handler could be like void UART1_Handler(void) { ... // processing task for the peripheral return; } For users of the CMSIS compliant device driver library, the interrupt handler name should match the interrupt handler name defined by the Microcontroller Unit (MCU...
// ISR Example, Week 6c - Interrupts in C (David Morris, 2022) void interrupt ISR() { // 检查计时器0的中断是已使能的,且中断发生了 if (TMR0IE && TMR0IFF) { // 进入中断 TMRIF = 0; // 清除 TMR0 的 IF } // 查看有无其他未执行的中断 } References: [1] PIC16F882/883/884/...

In C programming, you can use the intrinsic functions provided in Cortex Microcontroller Software Interface Standard (CMSIS) compliant device driver libraries or provided in the compiler to set and clear PRIMASK: void __enable_irq(); // Clear PRIMASK void __disable_irq(); // Set PRIMASK void...
Now that we have learned about interrupts, we are going to circle back to ourflashing LED application. Recall that in that exercise, we used a delay function to determine how long to wait before turning on the LED. This works great if you are doing very little else. If we want to do...

So, for external interrupt line 0, we simply need to create a void function duplicating the name used in the vector table: void EXTI0_IRQHandler (void); This now becomes ourinterrupt service routine. In addition, we must configure themicrocontroller peripheraland NVIC to enable the interrupt ch...
