UART

UART_Init

Defination	void UART_Init(uint32_t Baudrate)
Input Arguments	uint32_t : Baudrate to be configured.
Return Value	none
Description	This function is used to initialize the UART at specified baud rate.If the requested baud rate is not within the supported range then the default baud rate of 9600 is set.
Usage

Defination	void UART_TxChar(char ch)
Input Arguments	Ascii value of the character to be transmitted.
Return Value	none
Description	This function is used to transmit a char through UART module.
Usage

Defination	char UART_RxChar()
Input Arguments	none.
Return Value	char: Ascii value of the character received
Description	This function is used to receive a char from UART module. It waits till a char is received and returns it after reception.
Usage

Defination	*void UART_TxString(char string_ptr)**
Input Arguments	String(Address of the string) to be transmitted.
Return Value	none
Description	This function is used to transmit the ASCII string through UART.. The string_ptr points to the first char of the string and traverses till the end(NULL CHAR) and transmits a char each time
Usage

Defination	*void UART_RxString(char string_ptr)**
Input Arguments	*char string_ptr** Address of the string where the received data needs to be stored
Return Value	none
Description	This function is used to receive a ASCII string through UART till the carriage_return/New_line The stream of data is copied to the buffer till carriage_return/New_line is encountered. Once the Carriage_return/New_Line is received the string will be null terminated.
Usage

Defination	void UART_TxDecimalNumber(uint32_t num, uint8_t NumOfDigits )
Input Arguments	uint32_t: Number to be transmitted on UART. uint8_t : Number of digits to be transmitted
Return Value	none
Description	This function is used to transmit a max of 10digit decimal number.2nd parameter specifies the number of digits from the right side to be transmitted . The output for the input combinations is as below. (12345,4) then 4-digits ie. 2345 will be transmitted (12345,6) then 6-digits ie. 012345 will be transmitted (12345,C_DefaultDigitsToTransmit) then 12345 will be transmitted.
