Function Documentation

◆ delay()

void delay ( uint32_t  ms)

Delay in milliseconds.

Returns
Void.

◆ delayMicroseconds()

void delayMicroseconds ( uint32_t  us)

Delay in microseconds.

Returns
Void.

◆ micros()

uint32_t micros ( void  )

Gets system time in microseconds. 

This can be called from within IRQ Handlers, so uses LDREX/STREX.
If a higher priority IRQ or DMA or anything happens the STREX will fail
and restart the loop. Otherwise the same number that was read is harmlessly
written back.
Returns
uint32_t Time in microseconds.

◆ millis()

uint32_t millis ( void  )

Gets system time in milliseconds.

Returns
uint32_t Time in milliseconds.

◆ SystemClock_Config()

void SystemClock_Config ( void  )

◆ systemInit()

void systemInit ( void  )

Initializes system.

Returns
Void.

◆ SysTick_Handler()

void SysTick_Handler ( void  )

This function handles System tick timer.
