UART

UART_Init

{{#Widget:LibTable}}
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

UART_TxChar

{{#Widget:LibTable}}
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

UART_RxChar

{{#Widget:LibTable}}
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

UART_TxString

{{#Widget:LibTable}}
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

UART_RxString

{{#Widget:LibTable}}
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
  1. 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.
