LCD都需要背光,而OLED不需要,因为它是自发光的。另外,OLED的功耗比LCD低得多,相同显示面积的功耗仅相当于LCD的1/3。OLED尺寸难以大型化,但是分辨率确可以做到很高,非常适合手持式移动设备。 这里用0.96 168x64常见的1.3寸OLED显示屏分为SPI和I2C两种通信方式,白色、蓝色、黄蓝双色三种颜色。 购买7pin,可以学习iic...
ESP32+i2c+LCD Postbynigelt»Fri Mar 08, 2024 5:53 pm I'm trying to use an ESP32-S. I have connected an LCD via pins 21 and 22 (plus power). The program compiles but the display never changes. I have run an i2c finder progrma and that comes back with the default 0x27 for...

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...
The ESP32 will communicate with the PCF8574, which uses I2C communication, and this in turn will control the LCD. ADVERTISEMENT The PCF8574 I2C expander is shown below. As you can see abovePCF8574has 4 input pinsGND, VCC, SDA, SCLand 16 output pins. We will connect our LCD1602 to thes...
