Detailed Description

Repetitive Interrupt Timer (RIT) class.

Sample Code:

DigitalOut rit_led(LED3);

//Our function isr. void RIT_IRQHandler(void) { rit_led=!rit_led; // Flash a Led }

RIT rit(1000); //Set interval to 1000 ms or 1 second.

rit.append(RIT_IRQHandler); //Append our own function ISR. rit.enable();

wait(10); //wait 10 seconds (and watch the led flashing).

rit.disable(); rit.unappend();

Constructor & Destructor Documentation

RIT ( uint32_t  ms )

Constructor.

ms the number of milliseconds between two interrupts.

Member Function Documentation

void append ( void(*)(void)  fptr )

Append function isr to global interrupt handler.

fptr the function isr to be called from within the default interrupt handler.

void attach ( void(*)(void)  fptr )

Attach custom interrupt handler replacing default.

fptr the new interrupt handler.

Definition at line 78 of file RIT.cpp.

void detach ( void   )

Restore default interrupt handler.

Definition at line 84 of file RIT.cpp.

void disable ( void   )
