Function Documentation

static uint16_t Buffercmp	(	uint8_t *	pBuffer1,
		uint8_t *	pBuffer2,
		uint16_t	BufferLength
	)		`[static]`

Compares two buffers.

Parameters:

pBuffer1,pBuffer2,:	buffers to be compared.
BufferLength,:	buffer's length

Return values:

0	: pBuffer1 identical to pBuffer2 >0 : pBuffer1 differs from pBuffer2

< 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
