Universal Software Timer Main Page
This is an easy-to-use universal software timer library, for use with any hardware timer, featuring automatic determination of needed timer parameters on precompile, up to 256 independant software timers, each can be enabled/disabled and an interrupt queue if more than one sw interrupt occured at once.
Free for personal use, credits and a short mail with your project info and/or comments, improvements etc. to this library would be nice.
How to use this
the values are just for example
$crystal = 16000000 '[...] ' your Code Const False = 0: Const True = 1 ' make it more readable Const Ticker_hwtimer = 0 ' Choose which hardware timer to use Const Ticker_frequency = 10000 ' set the timer resolution Const Tickers = 2 ' # of software timers to use $include "tickers.bas" Ticker_time(1) = 25 ' Interrupt Ticks to trigger SW-Timer 1 Ticker_time(2) = 500 ' SW-Timer 2 and so on... Ticker_enabled(1) = True ' Enable/Disable SW-Timer Ticker_enabled(2) = False '[...] Enable Interrupts
>Do '[...] Select Case Ticker_get_interrupt() ' make sure that this function is called at least once per ' hw timer overflow, so don't make the µC hanging around Case 1: ' Ticker 1 triggered an interrupt '[...] Case 2: ' Ticker 2 interrupt '[...] End Select '[...] Loop
