SPI LCD Example

The example demonstrates how to develop different model LCDs with SPI interface using standalone drivers and test them by displaying color bars.

How to use

1. Configure drivers if needed.
2. Modify the macros in the example to match the parameters according to your hardware.
3. Navigate to the Tools menu in the Arduino IDE to choose a ESP board and configure its parameters, please refter to Configuring Supported Development Boards
4. Verify and upload the example to your ESP board.
