RemoteLCD

What is RemoteLCD?

RemoteLCD is a small project that allows you to communicate with a remote ESP32 device and display messages on a TFT LCD screen.

What are the required components?

You will need:

• an ESP32-C3 Supermini or ESP32 classic
• a TFT LCD with the ST7789 driver, 1.9" 170x320 resolution in my case, but you can personalize
• a DHT22 temperature sensor to get the local temperature

Setting up the Esp32 or Esp32-c3 supermini

in the folder ESP32_RemoteLCD you have a file ESP32_RemoteLCD\config.h.example to copy into ESP32_RemoteLCD\src\config.h and ESP32_RemoteLCD\config.cpp.example to copy into ESP32_RemoteLCD\src\config.cpp where you need insert your credentials for wifi connection and other params.

For flash and open serial monitor for esp32c3 use

sudo pio run -e esp32-c3 -t upload && sudo pio device monitor -e esp32-c3 -b 115200

and for esp32 classic

sudo pio run -e esp32 -t upload && sudo pio device monitor -e esp32 -b 115200

• -e is the environment, esp32c3 or esp32
• -t is the target, beacouse we want upload the code to the device
• -b is the baud rate of the serial communication, the speed
