RESTART while(1), after occcuring an interrupt

[akhilfrancis]

Hi,

Is it possible to restart while(1) in c code, after occurring an interrupt / satisfying any conditions

 

[Easyrider83]

while(1) - is a loop forever. Don't understood the question.

Hello!

Being a while(1), when you get out from the interrupt ore from a conditions, you shoul get back to the main.

If not something wrong must happen!

Hope to be helpful

while running the while loop, in middle of the while loop, i i got an interrupt. is it possible restart the while loop from the begining

But how do you know you are in the middle or beginning when interrupt happens?

Hi,

for me it makes no sense.

This means you don´t finish your current operation/function ... then for sure you need to initailize a lot of processes again.

Example:
* Let´s assume you are in the middle of an I2C, SPI or UART communication.. and don´t finish it. What happens to the bus sate and protocol?

* Or you are just in a function and you had some data pushed on the stack... how do you decide to handle this?

Let the watchdog conter overflows, so your program will be interrupted and will restart from beginning. Anyway, the question itself do not make sense at all, considering that this would imply in a break on the program execution.

Set a flag in the ISR which is tested at an appropriate point in the while loop and causes it to execute a 'continue' statement.
At least that way you retain control of whatever processing is occurring in the 'while' loop.
