I would say, see how long it is taking to get into Int1 and complete the whole job.


Also, why not using 20Mhz?


BTW: This post should be the continuation of the first one you started with.

Also, some Gosubs in a ISR is really not recommended. ISRs must be short. Here you spend toooo much time.

Hi mister_e and expert person

Do you have any advise for how to optimize code to shot...

So this code we did covert form c code to basic code (me),the original code used 4 mhz work ok no flashing on display
