Digital pins 0—15 can beINPUT,OUTPUT, orINPUT_PULLUP. Pin 16 can beINPUT,OUTPUTorINPUT_PULLDOWN_16. At startup, pins are configured asINPUT. Pins may also serve other functions, like Serial, I2C, SPI. These functions are normally activated by the corresponding library. The diagram below ...
esp8266开发入门教程(基于Arduino)——环境安装 2.2 安装库 打开Arduino IDE,依次打开 工具 -> 管理库… 在搜索框输入需要安装的库名称,找到对应的库,点击安装即可。 本文需要使用的Arduino库如下: 关于LCD驱动的库其实有很多,之所以用TFT_eSPI是因为这个库比较通用,支持很多驱动IC,而且有些图形库也依赖于这个库。...

To test this setup, wire a pushbutton to your ESP8266 board as shown in the following schematic diagram. When you press the pushbutton, the RST pin goes LOW. If you’re using anESP-01, follow the next diagram instead. ESP8266 External Wake Up Sketch ...
Arduino ESP8266 使用LittleFS存储配置文件实践 首先引用前辈的文章,了解一下esp8266 的flash 布局layout: ESP8266 flash布局(layout) 支持flash为512KB, 1M, 2M, 4M. 4KB为1个扇区,也就是16进制的0x1000. 4096 非OTA布局 a) 前64个扇区256KB烧写主程序+用户数据+用户参数, 主程序文件名eagle.flash.bin, 最...
Holding the board with the two USB ports to the left and the “L”-shaped, metal RF shield to the right, pin-1 of the forty pin connector is at the right-hand side of the board (next to the mounting hole and slightly above and in from the power switch) on the top row of pins...
As we can see in the above diagram, one terminal of the push-button is connected by RST through the resistor and 3.3V power supply. The other end of the terminal is common ground with the board. Arduino Sketch ESP8266 External wake up ...
