SX/B Tutorial on Interrupts

John Couture

Recently I needed to use an interrupt for a project and I dove in and learned enough to be dangerous.· Attached is a pretty simple·tutorial that should help anyone that is having difficulty with interrupts.· File is 4 page·pdf (this bbs does not allow the upload of html).

Since you're using SX/B you may want to explain the RATE parameter of the INTERRUPT keyword -- automates the setting of the OPTION register and prevents recalculation when you make a change in system frequency or the interrupt rate.

I'm waiting for the next chapter (it was mentioned twice.)· !

Will it be out before that SX/B book is released?

As I am employing a roomfull of monkeys typing random characters, I suspect that "the book" will take a while (statictically speaking). I have the next chapter about half done. Give me a week and I should have something to post.

Port-Interrupts.pdfThe first tutorial above was about RTCC Interrupts (Timed Interrupts). Here is the next chapter on Port Triggered Interrupts. Sorry it took so long, I wrote this a long time ago and must have forgotten to upload it to this forum.

I'm glad that you remembered, it's a great refresher/reminder of how the SX does it's interrupt processing. Thank you!
