hd44780-stm32hal's Introduction

HD44780 Lcd - stm32 HAL

HD44780 16x2 Lcd library for stm32 using stm32-hal library's.

Library is developed and tested with Stm32F411-discovery and the given example.

Features:

4bit & 8bit mode
Multiple lcd support
String printing
Number printing
Set cursor position
Clear screen

Using 16xN and 20xN screens

Set macros for different screen sizes in lcd.h. By default, 16xN is enabled.

// #define LCD20xN 		// For 20xN LCDs
#define LCD16xN			// For 16xN LCDs

8bit example

Lcd_PortType ports[] = {
	D0_GPIO_Port, D1_GPIO_Port, D2_GPIO_Port, D3_GPIO_Port,
	D4_GPIO_Port, D5_GPIO_Port, D6_GPIO_Port, D7_GPIO_Port
};

Lcd_PinType pins[] = {D0_Pin, D1_Pin, D2_Pin, D3_Pin, D4_Pin, D5_Pin, D6_Pin, D7_Pin};

Lcd_HandleTypeDef lcd;

lcd = Lcd_create(ports, pins, RS_GPIO_Port, RS_Pin, EN_GPIO_Port, EN_Pin, LCD_8_BIT_MODE);

Lcd_string(&lcd, "4ilo - 8bit");

Lcd_cursor(&lcd, 1,6);
Lcd_int(&lcd, -500);

4bit example

Lcd_PortType ports[] = {
	D4_GPIO_Port, D5_GPIO_Port, D6_GPIO_Port, D7_GPIO_Port
};

Lcd_PinType pins[] = {D4_Pin, D5_Pin, D6_Pin, D7_Pin};

Lcd_HandleTypeDef lcd;

lcd = Lcd_create(ports, pins, RS_GPIO_Port, RS_Pin, EN_GPIO_Port, EN_Pin, LCD_4_BIT_MODE);

Lcd_string(&lcd, "4ilo - 4bit");

Lcd_cursor(&lcd, 1,6);
Lcd_int(&lcd, -500);
