深入解析NHD-0416BZ-FL-YBW字符液晶顯示模塊

在電子設(shè)計(jì)領(lǐng)域,液晶顯示模塊是人機(jī)交互的重要組成部分。今天我們來詳細(xì)探討Newhaven Display International推出的NHD - 0416BZ - FL - YBW字符液晶顯示模塊,它具有諸多特性,能滿足多種應(yīng)用場(chǎng)景需求。

產(chǎn)品概述

NHD - 0416BZ - FL - YBW模塊從型號(hào)上就可以看出其特點(diǎn):

  • “NHD - ”代表Newhaven Display。
  • “0416 - ”表明該模塊有4行,每行可顯示16個(gè)字符。
  • “BZ - ”是特定的型號(hào)標(biāo)識(shí)。
  • “F - ”表示采用了半透反射技術(shù)。
  • “L - ”說明配備了黃綠LED背光源。
  • “Y - ”代表STN正性黃綠顯示。
  • “B - ”意味著最佳視角為6點(diǎn)鐘方向。
  • “W - ”表示具備寬溫度工作范圍,并且該產(chǎn)品符合RoHS標(biāo)準(zhǔn)。

功能與特性

初始化程序

8位初始化

void command(char i) 
{ 
    P1 = i; //put data on output Port
    D_I = 0;
    D_I = 0; //D/I = LOW : send instruction 
    R_W = 0; //R/W = LOW:Write
    E = 1;
    Delay (1);
    Delay(1); //enable pulse width >= 300ns 
    E = 0; //Clock enable:falling edge
}

void write(char i) { 
    P1 = i; //put data on output Port 
    R_W = 0; 
    D_I = 1; //D/I = HIGH : send data //R/W = LOW:Write
    E = 1; 
    Delay (1);
    Delay(1); //enable pulse width >= 300ns 
    E = 0;
    E = 0; //Clock enable: falling edge 
} 

void init() 
{
    E = 0; 
    Delay(100); //Wait >40 msec after power is applied 
    Delay (100);
    command (0x30); //command 0x30 = Wake up
    Delay(30);
    Delay(30); //must wait 5ms, busy flag not available 
    command (0x30); //command 0x30 = Wake up #2
    Delay (10); Delay(10); //must wait 160us, busy flag not available 
    command (0x30); //command 0x30 = Wake up #3
    Delay (10);
    Delay(10); //must wait 160us, busy flag not available 
    command (0x38);
    command(0x38); //Function set: 8 - bit/2 - line 
    command (0x10); 
    command (0x0c); 
    command (0x06); //Set cursor //Display ON; Cursor ON //Entry mode set
}

4位初始化

    P1 = 0x30;
    Delay (30);
    Delay(30); //must wait 5ms, busy flag not available 
    Nybble(); //command 0x30 = Wake up
    Delay (10);
    Delay(10); //must wait 160us, busy flag not available 
    Nybble(); //command 0x30 = Wake up #2
    Delay (10);
    Delay(10); //must wait 160us, busy flag not available 
    Nybble ();
    Nybble(); //command 0x30 = Wake up #3 
    Delay(10); //can check busy flag now instead of delay 
    Delay (10);
    P1 = 0x20; //put 0x20 on the output port 
    P1 = 0x20;
    Nybble(); //Function set: 4 - bit interface 
    Nybble ();
