商品簡介 |
Twig - OLED 96x96 twig 是一款 16 色灰度 96×96 點陣 OLED 顯示模組,具有 Grove 兼容的 4pin I2C 接口。Twig - OLED 96x96 由 96 x 96 點陣 OLED 模組([ LY120])和 SSD1327 驅動 IC 構成。 該顯示模組的特點是高亮度、自發光、高對比度、超薄/超薄外形、寬視角、寬溫度範圍、低功耗。
用於 Seeeduino 和 Arduino 的圖形顯示適配器,使用 Grove 乾板。 適用於任何支持 I²C 接口的 5V 或 3.3V MCU 的顯示適配器。 可與 mbed 微控制器一起使用。
對於所有 Grove 用戶(尤其是初學者),我們為您提供指導 PDF 文檔。 在使用該產品之前,請下載並閱讀入門和 Grove 簡介。
如何查詢I2C位址 |
STEP 1. 將欲查詢的模組連接至Arduino UNO(附圖為腳位參考,實際請比對商品標示接線)
STEP 2. 開啟Arduino IDE並新增檔案
STEP 3. 貼入教學下方的範例文件,並上傳到Arduino UNO,即會開始掃描I2C位址
STEP 4. 開啟序列埠監控視窗,即可取得I2C位址

// Arduino I2C Scanner | |
// Re-writed by Arbi Abdul Jabbaar | |
// Using Arduino IDE 1.8.7 | |
// Using GY-87 module for the target | |
// Tested on 10 September 2019 | |
// This sketch tests the standard 7-bit addresses | |
// Devices with higher bit address might not be seen properly. | |
