Nokia_5110显示屏STM32F103x开发

2021-11-22 来源：eefocus

一、显示屏模块选型

1.1 Nokia 5110 LCD（蓝屏）液晶屏模块

在这里插入图片描述

1.2 简介：

1.3 显示屏显示分成 5 行

在这里插入图片描述

二、程序开发

这里有两个，关于显示数据的数组，我把放在两个不同的头文件中，一个为了方便显示英文，一个为了方便显示中文。英文操作简单一点。

2.1 main函数

程序链接：

https://download.csdn.net/download/qq_37788383/11887775

#include 'stm32f10x.h'

#include 'delay.h'

#include 'sys.h'

#include 'usart.h'

#include 'nokia_5110.h'

char juli[8]='-----.-';

double temp = 23563.7;

int main(void)

{

delay_init(); //延时函数初始化

NVIC_PriorityGroupConfig(NVIC_PriorityGroup_2); //设置NVIC中断分组2:2位抢占优先级，2位响应优先级

LCD_init();

//显示有三种方式 x为0-83，y为0-5

// 1) LCD_write_english_string(0,0,'LOCATION OK '); 显示英文字母

// 2) LCD_write_string(0,2,juli,7); 显示数字，阿拉伯字母

// 3) LCD_write_chinese_string(X, Y,ch_with,num,line,row); 显示汉字（不大好用啊）

/*******************************************

*目的：在LCD上显示汉字

*参数：X、Y -- 显示汉字的起始X、Y坐标

* ch_with -- 汉字点阵的宽度

* num -- 显示汉字的个数

* line -- 汉字点阵数组中的起始行数

* row -- 汉字显示的行间距

*******************************************/

while(1)

{

juli[0]=(int)temp%100000/10000+0x30;

juli[1]=(int)temp%10000/1000+0x30;

juli[2]=(int)temp%1000/100+0x30;

juli[3]=(int)temp%100/10+0x30;

juli[4]=(int)temp%10+0x30;

juli[6]=(int)(temp*10)%10+0x30;

LCD_write_string(0,2,juli,7); //显示数字，阿拉伯字母

LCD_write_english_string(0,0,'LOCATION OK '); //显示英文字母

}

2.2 模块.h文件

#ifndef __NOKIA5110_H_

#define __NOKIA5110_H_

#include 'sys.h'

#define SCLK PBout(1) //串行时钟线

#define SDIN PBout(12) //串行数据线

#define LCD_DC PBout(13) //模式选择： 1 写数据，0 写指令

#define LCD_CE PBout(14) //芯片使能

#define LCD_RST PBout(15) //复位，低电平有效

#define LCD_BL PBout(0) //背光

void LCD_init(void);

void LCD_clear(void);

void LCD_write_english_string(unsigned char X,unsigned char Y,char *s);

void LCD_write_string(unsigned char X,unsigned char Y,char *s,char length);

void LCD_write_chinese_string(unsigned char X, unsigned char Y,

unsigned char ch_with,unsigned char num,

unsigned char line,unsigned char row);

void LCD_draw_bmp_pixel(unsigned char X,unsigned char Y,unsigned char *map,

unsigned char Pix_x,unsigned char Pix_y);

#endif
