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

05L002008.png
  • 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)果中會輸出內(nèi)碼值,程序中直接使用即可
如圖所示:

接口說明

12864 液晶串口接口管腳信號說明
管腳號 名稱 LEVEL 功能描述
1 GND 0V 電源地
2 VCC +5V 電源正(3V - 5.5V)
3 V0 - 對比度亮度調(diào)整
4 RS H / L 模組片選端,高電平有效
5 R / W H / L 串行數(shù)據(jù)輸入端
6 E H / L 串行同步時(shí)鐘:上升沿時(shí)讀取數(shù)據(jù)
15 PSB L 串口方式
17 RST H / L 復(fù)位端,低電平有效
19 A 5V 背光源電壓 +5V
20 K GND 背光源負(fù)端 0V


注意:1、實(shí)際應(yīng)用中僅使用串口通訊模式,可以將PSB接固定的低電平
2、模塊內(nèi)部接有上電復(fù)位電路,因此在不需要經(jīng)常復(fù)位的場合,可以將復(fù)位引腳懸空

管腳號 名稱 LEVEL 功能描述
1 GND 0V 電源地
2 VCC +5V 電源正(3V - 5.5V)
3 V0 - 對比度亮度調(diào)整
4 RS H / L RS =“H”,表示 DB7 - DB0 為顯示數(shù)據(jù)
RS =“L”, 表示 DB7 - DB0 為顯示指令數(shù)據(jù)
5 R / W H / L R / W = “H”,E = “H”,數(shù)據(jù)被讀到 DB7 - DB0
R / W = “L”,E = “H - L”,DB7 - DB0的數(shù)據(jù)被寫到 IR 或 DR
6 E H / L 使能信號
7 DB0 H / L 三態(tài)數(shù)據(jù)線

15 PSB H/L H:8 位或 4 位并口方式,L:串口方式
16 NC - 空腳
17 RST H / L 復(fù)位端,低電平有效
18 VOUT - LCD 驅(qū)動電壓輸出端
19 A 5V 背光源電壓 +5V
20 K GND 背光源負(fù)端 0V


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
