使用方法
聲明:此款 LCD12864 液晶為未焊接連接件(排針)的版本,所以購買后您需要自行準(zhǔn)備排針焊接,如果您不進(jìn)行接口焊接,可能會(huì)出現(xiàn)接觸不良的問題,而導(dǎo)致液晶屏不能正常顯示
軟件使用
- 圖片取模軟件使用方法
說明:如果要使用液晶屏顯示圖片,我們需要使用到圖片取模軟件,大家在頁面最后的相關(guān)資料內(nèi)可以下載
如下圖所示為軟件的操作界面:
(1)設(shè)置輸出格式為:C 語言
(2)點(diǎn)擊重設(shè)參數(shù),設(shè)置輸出大小,這里使用的是 12864 液晶顯示器,所以輸出大小為 X:128、Y:64
(3)點(diǎn)擊載入圖片,將要取模的圖片載入到軟件中
(4)點(diǎn)擊數(shù)據(jù)保存,將取模后的碼值保存到文件中
- 漢字內(nèi)碼提取軟件使用方法
(1)在待處理字符串中輸入要轉(zhuǎn)換內(nèi)碼的文字,例如輸入“奧松機(jī)器人”
(2)點(diǎn)擊轉(zhuǎn)換,轉(zhuǎn)換結(jié)果中會(huì)輸出內(nèi)碼值,程序中直接使用即可
如圖所示:

注意:1、如果在實(shí)際使用中僅使用并口通訊模式,可以將PSB連接到固定的高電平
2、模塊內(nèi)部有上電復(fù)位電路,所以在不需要經(jīng)常復(fù)位的場(chǎng)合可以將該引腳懸空
3、由于并行方式的接線非常麻煩,所以現(xiàn)在使用較多的為 SPI 的連接方式

#include "LCD12864R.h" #define AR_SIZE( a ) sizeof( a ) / sizeof( a[0] ) unsigned char show0[]={ 0xB9, 0xFE, 0xB6, 0xFB, 0xB1, 0xF5, 0xB0, 0xC2, 0xCB, 0xC9, 0xBB, 0xFA, 0xC6, 0xF7, 0xC8, 0xCB }; //哈爾濱奧松機(jī)器人 unsigned char show1[]="gharee.com"; void setup() { LCDA.Initialise(); // 屏幕初始化 delay(100); } void loop() { LCDA.CLEAR();//清屏 delay(100); LCDA.DisplayString(0,0,show0,AR_SIZE(show0));//第一行第三格開始,顯示文智位機(jī)器人 delay(100); LCDA.DisplayString(2,0,show1,AR_SIZE(show1));;//第三行第二格開始,顯示網(wǎng)址dfrobot.com/ delay(5000); }
