Nextion GPS Speedometer

thingiverse

This is a Multifunction GPS-Based Speedometer **Hardware Needed** * WeMos D1 Mini Microcontroller * GPS Module * Nextion NX2432T024 HMI Display * DHT22 Temperature/Humidity Sensor * Optional 128x64 IIC OLED Display * Jumper Wires **Displays on a Nextion display the following Data** * Speed * Heading * Current Time * Date * Temperature * Humidity * Heat Index **Library Dependencies** * Nextion by ITEAD Studio * ESP8266_SSD1306 by Fabrice Weinberg & Daniel Eichhorn * Adafruit Unified Sensor by Adafruit * DHT Sensor Library by Adafruit * TinyGPSPlus by Mikal Hart **Required Changes for Nextion** * NexConfig.h: Uncomment DEBUG_SERIAL_ENABLE, we're using Nextion debug Only Serial1 TX pin is connected, we can receive anything from Nextion ESP8266 Serial1 RX is available, it's not used internally by WeMos * NexHardware.h: Change timeout values to zero otherwise display will be very slow **Connections** * D1 GPIO5 SCL -- OLED * D2 GPIO4 SDA -- OLED * D3 -- DHT * D4 -- NexTion Serial1 Tx * TX -- GPS * RX -- GPS The program was written to use PlatformIO + Visual Studio Code. If you use Arduino, you will need to modify the name and include the proper libraries.
