或者,您可以按照下一个示意图将 ESP8266 连接到 OLED 显示屏。 在此示例中,我们使用的是 I2C 通信协议。ESP8266 中最适合 I2C 通信的引脚是GPIO 5(SCL) 和GPIO 4(SDA)。 如果您使用的 OLED 显示屏具有 SPI 通信协议,请使用以下 GPIOs。 GPIO 14: CLK GPIO 12: MISO GPIO 13: MOSI GPIO 15: CS 安...

五、咕咕咕 今天有个小老弟问我OLED的IIC驱动问题,正好我前段时间写了SPI的OLED驱动程序,也想把IIC的驱动补上,凑成一对O(∩_∩)O哈哈~ 今天就稍微总结一下IIC的驱动吧。 本次实验的平台是NodeMCU(ESP8266) 开发环境为安信可 ESP 系列一体化开发环境 SDK版本为 ver: 2.2.1 一、IIC驱动 IIC有硬件IIC和软件(...
Availability: ESP8266. I2C.stop() 在总线上发送一个终止位(SDA转换为高,SCL为高)。 Availability: ESP8266. I2C.readinto(buf, nack=True) 从总线中读取字节,并存入缓冲区中。读取的字节数量即为缓冲区的长度。接收除最后一个字节外的所有字节后,将在总线上发送ACK,NACK将在最后一个字节后发送。 Availability...

I'm trying to run Adafruit esp8266 breakout as i2c slave using gpio 13 as scl and 14 as sda. Going through the Wire library code, I found it inapplicable to run esp as i2c slave with changed pin configuration. For ordinary use of Wire li...
本次实验的目标是把I2C相关的搞定,再尝试驱动SSD1306 0.96寸OLED屏幕以及BME280传感器,最后将传感器读到的数据和实时时间显示在屏幕上。 2,硬件部分 2.1 I2C协议简介 I2C 通讯协议(Inter-Integrated Circuit)是由Philips公司开发的,由于它引脚少,硬件实现简单,可扩展性强, 不需要USART、CAN等通讯协议的外部收发设备,...
