Input Arguments
  • uint8_t: required Mode 4/8-bit
  • uint8_t: Number of lines of LCD
  • uint8_t: Number of Chars per line
Return Value none
Description This function is used to initialize the lcd.
It initializes the LCD for selected mode(4/8-bit) and Type(16x2/16x1 etc)
Usage LCD_Init(8,2,16) //Initialize 2x16 LCD in 8-bit Mode
LCD_Init(4,2,16) //Initialize 2x16 LCD in 4-bit Mode
LCD_Init(4,4,16) //Initialize 4x16 LCD in 8-bit Mode

LCD_CmdWrite

{{#Widget:LibTable}}
Defination void LCD_CmdWrite( uint8_t var_lcdCmd_u8)
Input Arguments 8-bit command supported by LCD.
Return Value none
Description This function sends a command to LCD.
Some of the commonly used commands are defined in lcd.h.
For more commands refer the data sheet.
The behaviour is undefined if unsupported commands are sent.
Usage

LCD_CmdWrite(0x0c); //Sets display On and Cursor Off
LCD_CmdWrite(CMD_DISPLAY_ON_CURSOR_OFF); //Recommended

LCD_Clear

{{#Widget:LibTable}}
Defination void LCD_Clear()
Input Arguments none.
Return Value none.
Description This function clears the LCD and moves the cursor to beginning of first line
Usage

LCD_Clear(); // Clears the lcd and sets the cursor to beginning of the first line.


LCD_GoToLine

{{#Widget:LibTable}}
Defination void LCD_GoToLine(uint8_t var_lineNumber_u8)
Input Arguments uint8_t: Line number to move the cursor.
Return Value none
Description This function moves the Cursor to beginning of the specified line. If the requested line number is out of range, it will not move the cursor.

Note: The line numbers run from 1 to Maxlines.
To avoid the confusion the below enums has to be used for selecting lines.
For four line LCD the enums are as below:

  • E_LcdLineOne
  • E_LcdLineTwo
  • E_LcdLineThree
  • E_LcdLineFour
Usage

LCD_GoToLine(1); //Moves the cursor to beginning of first line LCD_GoToLine(E_LcdLineOne); //Recommended usage



LCD_GoToNextline

{{#Widget:LibTable}}
Defination void LCD_GoToNextLine()
Input Arguments none
Return Value none
Description This function moves the Cursor to beginning of the next line. If the cursor is on last line and NextLine command is issued then it will move the cursor to first line.
Usage

LCD_GoToNextline(); //Moves the cursor to beginning of next line.



LCD_SetCursor

{{#Widget:LibTable}}
Defination void LCD_SetCursor(char var_lineNumber_u8,char var_charNumber_u8)
Input Arguments
  • row: line number(line1=1, line2=2)
    For 2line LCD the I/P argument should be either 1 or 2.
  • col: char number.
    For 16-char LCD the I/P argument should be between 0-15.
Return Value none
Description This function moves the Cursor to specified position.
  • Note:If the Input(Line/Char number) are out of range then no action will be taken
Usage

LCD_SetCursor(1,10); //Moves the cursor to 1st line 11th char. LCD_SetCursor(5,10); //No action taken as line 5 is out of range

LCD_DisplayChar

{{#Widget:LibTable}}
Defination void LCD_DisplayChar( char var_lcdData_u8)
Input Arguments uint8_t: ASCII value of the char to be displayed.
Return Value none
Description This function sends a character to be displayed on LCD.
Any valid ascii value can be passed to display the respective character
Usage

LCD_DisplayChar(65); //Displays 'A' on LCD
LCD_DisplayChar(0x41); //Displays 'A' on LCD
LCD_DisplayChar('A'); //Recommended usage



LCD_DisplayString

{{#Widget:LibTable}}
Defination void LCD_DisplayString(char *ptr_stringPointer_u8)
Input Arguments char*:String(Address of the string) to be displayed.
Return Value none
Description This function is used to display the ASCII string on the lcd.
Usage
 
void main()
{
   char myString[]={"hello, world"};
   LCD_DisplayString(myString);
   LCD_DisplayString("good morning");
}

LCD_ScrollMessage

{{#Widget:LibTable}}
Defination void LCD_ScrollMessage(uint8_t var_lineNumber_u8, char *ptr_msgPointer_u8)
Input Arguments
  • uint8_t: Line number on which the message has to be scrolled
  • char *: pointer to the string to be scrolled
Return Value none
Description This function scrolls the given message on the specified line.
If the specified line number is out of range then the message will be scrolled on first line.
  • Note: Leave 7-8 spaces at the beginning and 1 space at the end of the message to be scrolled.
Usage

LCD_ScrollMessage(" Welcome to embedded programming ");



LCD_DisplayNumber

{{#Widget:LibTable}}
Defination void LCD_DisplayNumber(NumericSystem_et e_typeOfNum_e8, uint32_t var_number_u32, uint8_t var_numOfDigitsToDisplay_u8)
Input Arguments
  • NumericSystem_et: Specifies type of number ENUM_BINARY(2),ENUM_DECIMAL(10), ENUM_Hex(16)
  • uint32_t: Number to be displayed on the LCD.
  • uint8_t : Number of digits to be displayed
Return Value none
Description

This function is used to display a max of 10digit decimal/Hex number OR specified number of bits for binary number.
1st parameter specifies type of number ENUM_BINARY(2),ENUM_DECIMAL(10), ENUM_Hex(16).
3rd parameter specifies the number of digits from the right side to be displayed.
The output for the input combinations is as below
Binary:

  • (10,4) then 4-LSB will be displayed ie. 1010
  • (10,8) then 8-LSB will be displayed ie. 00001010
  • (10,2) then 2-LSB will be displayed ie. 10

Decimal:

  • (10,12345,4) then 4-digits ie. 2345 will be displayed
