Function Documentation

static void CRC_Config ( uint32_t  poly) [static]

Configure CRC peripheral to use 32-bit polynomials.

Parameters:
poly,:the CRC polynomial
Return values:
None

Referenced by main().

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
