簡介

---

這是一個Nokia 5110用的液晶螢幕，2手良品 。

店家的說明

http://www.ltc.com.tw/product_info.php/products_id/60701

Nokia5110液晶螢幕是諾基亞手機的二手拆機螢幕，本店出售的液晶螢幕皆經供應商嚴格挑選與測試，請安心選購。

PCB提供上下兩排接線埠，排列如下：

1. RST：重定
2. CE：片選
3. DC：資料/指令選擇
4. DIN：串列資料線
5. CLK：串列時鐘線
6. VCC：電源輸入（DC3.3V 或 DC5V均可，經過實驗驗證，沒有問題）
7. BL：背光控制端
8. GND：地線

介面為串列SPI介面

規格簡述如下

他的解析度為 84x48 pixel 單色LCD，大小約1.5" ，他和文字型LCD不同的是

他可以顯示圖片（當然也就只有單色）。

他的LED背光，是可以用類別的輸出或是PWM來調整它的亮度，即使沒有背光，也不會

影響字的顯示。

/*
 * To use this sketch, connect the eight pins from your LCD like thus:
 *
 * Pin 1 -> +3.3V (rightmost, when facing the display head-on)
 * Pin 2 -> Arduino digital pin 3
 * Pin 3 -> Arduino digital pin 4
 * Pin 4 -> Arduino digital pin 5
 * Pin 5 -> Arduino digital pin 7
 * Pin 6 -> Ground
 * Pin 7 -> 10uF capacitor -> Ground
 * Pin 8 -> Arduino digital pin 6
 *
 * Since these LCDs are +3.3V devices, you have to add extra components to
 * connect it to the digital pins of the Arduino (not necessary if you are
 * using a 3.3V variant of the Arduino, such as Sparkfun's Arduino Pro).
