Using the counter for timeouts

Introduction #

Each cog has independent counters that can run in the background and support your code without overhead.

The counters can perform many operations, and here we mention using them for operation timers.

Code Snippet #

These code snippets show an efficient way to setup your own timeout and check them using the pollct instructions

1. Setup your own timeout

getct      timeout                         ' set timeout value
addct1     timeout,          ##delay1s       

2. Test if the timeout has been exceeded

pollct1    wc
if_c       jmp              #timed_out
