Detailed Description

The class that implements the active waiting pause.

It uses the SysTick that fires an interrupt each 1ms. All the elements are static so it doesn't need to be initialized.

int main (void){
    WAIT::init();   //sets the SysTick timer to fire each ms, activate the interrupts
                    //note that the class isn't instantiated
    WAIT::wait_ms(100); //wait 100ms
}

Member Function Documentation

static void STM32LIB::WAIT::init ( void  )

inlinestatic

Initiate the SysTick timer and sets the interrupts.

static void STM32LIB::WAIT::wait_ms ( uint32_t  ms )

inlinestatic

Wait for ms milliseconds.

Parameters

ms	the number of milliseconds to wait

static void STM32LIB::WAIT::wait_s ( uint32_t  s )

inlinestatic

Wait for ms seconds.

Parameters

s	the number of seconds to wait

void __attribute__

(

(interrupt("IRQ"))

)

The SysTick interrupt function.

Note the extern "C" and the weak attribute (this allows to be used for other libs)
