NodeMCU is an open sourceLuabased firmware for theESP8266 WiFi SOC from Espressifand uses an on-module flash-basedSPIFFSfile system. NodeMCU is implemented in C and is layered on theEspressif NON-OS SDK. The firmware was initially developed as is a companion project to the popular ESP8266-ba...
ESP8266驱动SH1306-1.3寸OLED屏幕(u8g2图形库) =/ U8X8_PIN_NONE); 函数形参并没有SDA和SCL引脚定义,是否是ESP8266有默认的I2C接口呢?我们来看下NodeMCU的定义: 默认的是SDA为4,SCL为5号引脚。 这里请注意:GPIO4、GPIO5分别对应板子上的D2、D1引脚。 具体接线方式请参考下图: 另外还需要将step()初始化函...
Pin configuration and the number of pins. To properly use the ESP8266 in your projects, you need to have access to the board pinout (like a map that shows which pin corresponds to which GPIO and its features). So make sure you have access to the pinout of the board you’re getting....

我这里使用的是相对便宜的NodeMCU（约人民币15-25元）,由于esp8266只支持802.11bgn,所以以下实验只针对...
【microPython与esp8266】之一——呼吸灯与PWM 呼吸灯与pwm pwm是什么? PWM的全称是脉冲宽度调制(Pulse-width modulation),是通过将有效的电信号分散成离散形式从而来降低电信号所传递的平均功率的一种方式: 简而言之,使用矩形方波(离散信号)来等价表示正弦波(连续信号)的方式.只要对方波调频,在输出端看来,就等价于...
First, connect the I2C module to the LCD. Solder Female Header pins to the LCD and connects the I2C module in such a way that the four pins of the I2C (GND, VCC, SDA, SCL) point outwards. Now,to power the circuit, connect the GND pin of the I2Cmodule to ...
