This is a Rust driver library for LCD displays using the ST7920 controller. It supports graphics mode of the controller, 128x64 in 1bpp. SPI connection to MCU is supported.

It implements embedded-graphics driver API.

It is platform independent as it uses embedded-hal APIs to access hardware.

The examples are based on the stm32f4xx_hal implementation of embedded-hal.

See examples.

The controller supports 1 bit-per-pixel displays, so an off-screen buffer has to be used to provide random access to pixels. Size of the buffer is 1024 bytes.

The buffer has to be flushed to update the display after a group of draw calls has been completed. The flush is not part of embedded-graphics API.
