ESP8266 Blink by Simon Peter. Blink the blue LED on the ESP-01 module. This example code is in the public domain. Hardware. Platform Espressif 32: ESP32 is a series of low-cost, low-power system on a chip microcontrollers with integrated Wi-Fi and Bluetooth. ESP32 integrates an antenna switch, RF balun, power amplifier, low-noise receive amplifier, filters, and power management modules. Microcontroller.
The WeMos D1 R2 is low-cost IEEE 802.11 b/g/n Wi-Fi capable microprocessor development board built around the ESP8266 Wi-Fi module. The ESP8266 is a low-cost Wi-Fi microchip,
Step 1. Plug the D1 Mini into your Windows machine. The first thing that you need to do is plug the D1 Mini board into your Windows machine. The board will be powered by the USB cable for this example. So you won't need an external power supply. Plug the USB cable into your Windows laptop or PC.
How the code works. First, you need to include theLiquidCrystal_I2C library. #include . The next two lines set the number of columns and rows of your LCD display. If you’re using a display with another size, you should modify those variables. int lcdColumns = 16; int lcdRows = 2;
Same deal with ESP32 SPI support: many pins are supported, but convention has uses four pins (5, 18, 19, and 23) so they’ve been lined up to their counterparts on ESP8266 D1 Mini. ESP8266 has only a single pin for analog-to-digital conversion. ESP32 has more flexibility and one of several ADC-supported pins was routed to the same place.
