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.

◆ systemInit()

void systemInit ( void )

Initializes system.

Returns: Void.

◆ SysTick_Handler()

void SysTick_Handler ( void )

This function handles System tick timer.
