Handy UART Setup Example


	#define USART1_BAUDRATE                         19200
	#define USART1_BRG                              (((GetSystemClock()/2)+(USART1_BRG_DIV/2*USART1_BAUDRATE))/USART1_BRG_DIV/USART1_BAUDRATE-1)
	#define BAUD1_ACTUAL                            ((GetSystemClock()/2)/USART1_BRG_DIV/(USART1_BRG+1))

	#define BAUD1_ERROR                             ((BAUD1_ACTUAL > USART1_BAUDRATE) ? BAUD1_ACTUAL-USART1_BAUDRATE : USART1_BAUDRATE-BAUD1_ACTUAL)
	#define BAUD1_ERROR_PERCENT_HUNDREDS            ((BAUD1_ERROR*10000+USART1_BAUDRATE/2)/USART1_BAUDRATE)

	#if (BAUD1_ERROR_PERCENT_HUNDREDS > 200)
		#error UART frequency error is worse than 2%
	#endif
