void Delay

(

__IO uint32_t

nTime

)

Inserts a delay time.

Parameters:

nTime,:

specifies the delay time length, in 10 ms.

Return values:

None

Definition at line 400 of file STM32F0xx_StdPeriph_Examples/I2C/I2C_WakeUpFromStop/main.c.

References TimingDelay.

void HardFault_Handler

(

void

)

This function handles Hard Fault exception.

Parameters:

None

Return values:

None

Definition at line 68 of file STM32F0xx_StdPeriph_Examples/I2C/I2C_WakeUpFromStop/stm32f0xx_it.c.

int main

(

void

)

Main program.

Parameters:

None

Return values:

None

< At this stage the microcontroller clock setting is already configured, this is done through SystemInit() function which is called from startup file (startup_stm32f0xx.s) before to branch to application main. To reconfigure the default setting of SystemInit() function, refer to system_stm32f0xx.c file
