I2C (Inter-Integrated Circuit) 集成电路总线是I2CBus的简称, 是一种串行通信总线, 使用多主从架构. 飞利浦公司在1980年代为了让主板, 嵌入式系统或手机用以连接低速周边设备而发展. I2C的正确读法为"I-squared-C"。 I2C只使用两条双向漏极开路(Open Drain): 串行数据SDA及串行时钟频率SCL总线, 且利用上拉电阻...

For OLED with I2C interface, there are several types of driver such as SSD1306, SH1106 driver . This tutorial uses SSD1306 I2C OLED Display 128x64 and 128x32 I2C OLED Display Pinout GND pin: should be connected to the ground of Arduino VCC pin: is the power supply for the display ...
Hi, I am reporting a problem with the library U8g2 with SH1106 I2C on Arduino (MEGA 2560). The screen is this one: "amazon.it/AZDelivery-Display-retroilluminato-Raspberry-gratuito/dp/B078J78R45" I am using the constructor line: U8G2_SH11...
这块128x64 OLED的裸屏是由SSD1306驱动的. 该芯片专为共阴极 OLED 面板设计, SSD1306 中嵌入了对比度控制器, 显示 RAM 和晶振, 并因此减少了外部器件和功耗. 有 256级亮度控制, 数据/命令的发送有三种接口可选择: 6800/8000串口, I2C接口或 SPI 接口. 适用于多数简单的应用, 移动电话的屏显, MP3播放器和...
这其实是一个很简单的问题,市场上在售的oled显示屏分为0.96和1.3 寸两个版本,当然这里面还有SPI和I2C不同接线的区分。0.96的驱动芯片是SSD1306,而1.3的驱动芯片是SH1106,由于不小心经常会给1.3用上SSD1306的驱动,导致了oled屏幕出现不稳定的情况,甚至出现白边,如下图所示: 如果是使用正确的SH1106驱动,那么则是...
