Timer Library

The mikroPascal PRO for AVR includes Timer library for easier handling of the internal Timer module of XMEGA devices.

Library Routines

Timer_Init
Timer_Interrupt_Enable
Timer_Interrupt_Disable

Timer_Init

Prototype

function Timer_Init(var module : byte; time : dword) : dword;

Returns

Number of uS which is set.

Description

Initializes the Timer/Counter (TC) module.

Parameters :

module: address of the desired desired TC module :

Value Description

TCC0 TC module 0 on PORTC.

TCC1 TC module 1 on PORTC.

TCD0 TC module 0 on PORTD.

TCD1 TC module 1 on PORTD.

TCE0 TC module 0 on PORTE.

TCE1 TC module 1 on PORTE.

TCF0 TC module 0 on PORTF.

TCF1 TC module 1 on PORTF.

time: Time interval in uS.

Requires

This routine is avaliable only for XMEGA devices.

Example

var time : dword;

time := Timer_Init(TCC0, 1000);

Timer_Interrupt_Enable

Prototype

procedure Timer_Interrupt_Enable(var module : byte);

Description

Enables TC overflow interrupt.

Parameters :

module: address of the desired desired TC module :

Requires

This routine is avaliable only for XMEGA devices.

Example

Timer_Interrupt_Enable(TCC0);

Timer_Interrupt_Disable

Prototype

procedure Timer_Interrupt_Disable(var module : byte);

Description

Disables TC overflow interrupt.

Parameters :

module: address of the desired desired TC module :

Requires

This routine is avaliable only for XMEGA devices.

Example

Timer_Interrupt_Disable(TCC0);
