EXAMPLE:The following C program shows the use of the LART functions.
Program description:
This program generates a PWM signal with a 10KHz frequency and with a 30% Duty cycle and
toggles an LED every second (Fcpu=8MHz ).
/* Program start */
#include "ST7lib_config.h"
/* prototype declaration */
void LART_OVF_IT_Routine(void);
void main(void);
static unsigned int count;
void main(void)
{
}
/* ----------------------------------------------------------------------------
#ifdef _HIWARE_
#pragma TRAP_PROC SAVE_REGS
#else
#ifdef _COSMIC_
@interrupt @nostack
#else
#error "Unsupported Compiler!"
#endif
#endif
ROUTINE NAME : LART_OVF_IT_Routine
INPUT
OUTPUT
DESCRIPTION : Interrupt service routine for Overflow interrupt
COMMENTS
-----------------------------------------------------------------------------*/
IO_Output(IO_PUSH_PULL,IO_PORT_B,IO_PIN_3);
/* Select Fcpu as counter clock & enable overflow interrupts
LART_Init( ((unsigned char)LART_COUNTER_CLK_FCPU |
EnableInterrupts
/* Load ATR and DCR to get PWM signal of 10 KHz and duty cycle of 30%
LART_PWM_Mode((unsigned int)0xCE0, LART_POLARITY_0,(unsigned int)0xDD0);
while(1);
LART is enabled. If the same functions are called in the
main Tree and the interrupt Tree, the function Re-entrant error
occurs in case COSMIC compiler is used with models other than
stack models.
For configuring the port pins,I/O library is used.

: This gets automatically executed when OVF interrupt of the

/* Additional registers will be saved */
/* Test for Metrowerks Compiler */
/* Compiler Defines not found! */
/* Port PB3 as pushpull output */
/* Clear I bit in CC register */
/* Test for Cosmic Compiler */
/* Generate PWM at PWM0 pin */
