# Minimal LCD demonstration on ESP-WROVER-KIT (ILI9341)

[![esp-wrover-kit-lcd-demo CI build](https://github.com/kekyo/esp-wrover-kit-lcd-demo/workflows/CI/badge.svg?branch=main)](https://github.com/kekyo/esp-wrover-kit-lcd-demo/actions?query=branch%3Amain)

## What is this?

This is a minimalist demonstration for using Ucglib on ESP-WROVER-KIT-VE (V1.4) with PlatformIO (Arduino framework).

ESP-WROVER-KIT is a reference evaluation board kit officially released by Espressif.

Useful beginnig with learning and understanding how to use ESP32 device architecture with reasonable cost.

You can choose for using Software-based SPI and Hardware-based SPI.

The method of composition is easily understood.

Hope this helps someone.

## Note

* ESP-WROVER-KIT older version maybe doesn't run this demo code, because LCD controller is different.

* ESP-WROVER-KIT has connectivity of debugger. In other words, you can debug your ESP32 code from VSCode. If you want to use debugger:

  * you have to configure "Bit-bang JTAG mode" on the serial device driver. [See also: Configure ESP-WROVER-KIT JTAG Interface](https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-guides/jtag-debugging/configure-ft2232h-jtag.html).

  * Start debugging with F5 key instead of write icon (right arrow). Debugger takes a long time to connect to the device (especially the first time!). Wait patiently until the "DEBUG CONSOLE" tab appears.
