ST7789V2 Display Driver
======================

This crate provides a driver for the ST7789V2 display, enabling basic operations such as initialization, clearing the screen, setting pixels, drawing images, and displaying buffers. The driver is built using the `embedded-hal` and `embedded-graphics` crates to ensure compatibility with various embedded platforms.  The crate has been updated to accommodate the latest versions of `embedded-hal` and `embedded-graphics`.

### Legacy Support in Version 0.3.2

For projects that still rely on the older version of the crate, **version 0.3.2** continues to provide compatibility with **embedded-graphics 0.7.1**. This is useful for maintaining projects that use older libraries or hardware.
