WebAnswer: NO. A mutex may lead to sleep and it's illegal to sleep in an interrupt service routine. Anyway, you can't use a mutex within an interrupt (because you can't put interrupt handlers to sleep), however you can use a spin lock instead. Spin locks are better because they are optimized for the... WebAug 18, 2016 · 2. You're right, you aren't passing the variable correctly. The way you have it, when the function is called you create a local variable (local to the function) and assign it the value of your global boton_flag. There are two ways that you could fix this: 1.

As you've discovered, interrupt routines are intended to perform quick handling of an external event, and defer additional work to other facilities. This is why, in your case, the delay loop causes the board to lock up: no other work is being performed while the code is sleeping inside the interrupt handler.

WebDec 28, 2024 · The next thing you need to get your head around is that there are NOT individual interrupt vectors for each peripheral. All PIC18 chips (apart from the K42 family), can either work in "Compatibility mode" which has a single interrupt service routine, or "Native mode", which has two routines (called "high" and "low" priority). WebNov 22, 2016 · Sorted by: 9. The main goal of the TX interrupt (really an END OF TX) is to send the content of a buffer (multiple bytes) automatically. When implemented in a proper way: Enable the TX interrupt. The user code starts transmission by sending only the first byte in the buffer. At the end of TX (of the first byte), an interrupt will be generated.

WebIt doesn't seem like you would want to treat your 5ms interrupt the same as a 1s interrupt, but if you were dead set on that type of architecture, all the interrupt routines can have the same code in them. That, of course, would use up some extra program memory, even if you just have all the interrupts call the same subroutine. WebTalk. In computer systems programming, an interrupt handler, also known as an interrupt service routine or ISR, is a special block of code associated with a specific interrupt condition. Interrupt handlers are initiated by hardware interrupts, software interrupt instructions, or software exceptions, and are used for implementing device drivers ...

WebmikroC recognizes an interrupt routine to be executed as the void interrupt() function. The body of that function, i.e. interrupt routine, should be written by the user.
