Design problem!!! Interrupt choking

Design problem!!!

I GET A FASTER Sensitive INPUT DATA IN AN INTERRUPT WHICH PRVENT ME TO PROCESS DATA IN THE MAIN PROGRAM( putchar + getchar).
one way is to disable interrput then process the data in the main after you finish activate it again but any way you lose data;

are there any other solutions to this problem
thanks;

Re: Design problem!!!

Can you not write the program so that the interrupt does nothing but store the received byte into a circular buffer and then return from interrupt?
The main program then does all the processing of the data.

Hi

You need to use a small routine (few line) for the interrupt and a ring buffer to receive and extract data for processing

This method might solve some of the problem you mentioned

All the best
