Ok, I guess I found the solution. But I need to wait for tomorrow to try it out. So after I try it, I will share my problem and my solution together.

The project is simple. There are 20 leds connected to PIC I/O, and they turn on and off according to some pattern. For example, one pattern: only first one of them is on and then only second ... goes ...

Hi.
In the code below, I change the value of "action" once external interrupt is triggered (by a button Smile

). Then, the action according to action's value is executed, after the last one ...

Your problem is that you're doing something (printing to the LCD) which takes a LONG time, inside an interrupt service routine. If a new CAN message arrives before the first ISR has been serviced, ba ...

Hi. I am working on a CAN bus project. There are two (actually many but for now only two) nodes on bus, each of them is a 18F458 (with MCP2551 of course) connected to LCDs. In one of them, two buttons ...
