7-7 顯示15x16字形

一、15x16字形

使用 Arduino 板控制 LCD 顯示一位 15x16 數字字形計數 0~9,每秒上數加 1。 15x16 字形是由 6 個 5x8 固定大小的字形所組成。

如圖所示編號 0~7 等 8 個 5x8 自建字形,再由這些自建字形整合成 15x16 數字字形,例如數字"0"依序由左而右、再由上而下是由編號 0、6、0、0、7、0 等 6 個 5x8 自建字形所組成。 

 

 

二、範例程式

從0-9循環顯示

#include <Wire.h>  // Arduino IDE 內建
#include <LiquidCrystal_I2C.h>
LiquidCrystal_I2C lcd(0x27, 2, 1, 0, 4, 5, 6, 7, 3, POSITIVE);

byte shape[8][8]={
{B11111,B11111,B11111,B11111,B11111,B11111,B11111,B11111}, //0
{B00000,B00000,B00000,B00000,B00000,B00000,B00000,B00000}, //1
{B11111,B11111,B00000,B00000,B00000,B00000,B00000,B00000}, //2
{B00000,B00000,B00000,B00000,B00000,B00000,B11111,B11111}, //3
{B11111,B11111,B00000,B00000,B00000,B00000,B00000,B11111}, //4
{B11111,B00000,B00000,B00000,B00000,B00000,B11111,B11111}, //5
{B11111,B00000,B00000,B00000,B00000,B00000,B00000,B00000}, //6
{B00000,B00000,B00000,B00000,B00000,B00000,B00000,B11111}}; //7
const char number[10][6]={
{0,2,0,0,3,0},{1,0,1,1,0,1},{4,4,0,0,5,5},{2,4,0,3,5,0},{0,7,0,6,6,0},
{0,4,4,5,5,0},{0,4,4,0,5,0},{2,2,0,1,1,0},{0,4,0,0,5,0},{0,4,0,5,5,0}};
void setup() 
{
  lcd.begin(16,2); 
  for(int i=0;i<8;i++)
     lcd.createChar(i,shape[i]);   
}   
void loop() 
{
  for(int i=0;i<10;i++)
  {
    showNumber(i,6);
    delay(1000);
  }  
}
void showNumber(int value,int colPosition)
{
  int i;
  lcd.setCursor(colPosition,0);
  for(i=0;i<=2;i++)
     lcd.write(byte(number[value][i]));
  lcd.setCursor(colPosition,1);  
  for(i=3;i<=5;i++)
     lcd.write(byte(number[value][i]));
 }

 

三、練習

1.設計 Arduino 程式,控制 LCD 顯示一位 1516 數字字形計數 0~9,每秒下數減 1。

2.設計 Arduino 程式,控制 LCD 顯示兩位 1516 數字字形計數 00~99,每秒上數加 1。
