Timer Peripheral Library

This library allows you to:

  • Set the clock source for the timer
  • Read and set the timer value
  • Read and set the timer period match value
  • Start and stop the timer
  • Set 8-, 16- or 32-bit data width for the timer
  • Operate in SLEEP, IDLE, or DEBUG modes
  • Set the pre- and post-scaler settings
  • Control timer special event trigger settings
  • Control asynchronous clock counter mode for Timer1
  • Control gated clock counter mode

The Timer Peripheral Library (PLIB) controls the timers by accessing the timer's Special Function Registers (SFRs). Timer SFR access is by function rather than by name. The developer does not need to know an SFR name or the specific SFR bit-field when calling a timer PLIB function. The user just has to identify the specific timer and the function to be performed on that timer.

Example Library Functions

Stopping a Timer
Stop Timer3
Configuring a Timer
Use internal peripheral clock to drive Timer1
Set Timer2 prescale value to 256
Configure Timer3 as a 16 bit timer/counter
Clear 16-bit Timer2 value
PLIB_TMR_Period16BitSet(TMR_ID_1, 0x1000);
Set 16-bit Timer1 period
Starting a Timer
Start Timer4
Reading a Timer's Current Value
MyVar = PLIB_TMR_Counter32BitGet (TMR_ID_2);
Get 32-bit Timer2 value

The PLIB parameter for specifying a timer (TMR_ID_x) is defined by the enum TMR_MODULE_ID. The default values for this enumeration equates Timer1 with TMR_ID_1, Timer2 with TMR_ID_2, …etc
