This is my first attempt at a moderately complex driver, criticism is welcome. I've included an example that works on the STM32_H405 board I recently added. The GPIO pins in the example were chosen so that they should match up with the exposed SPI port on the Feather_STM32F405 board as well, but I haven't tested that yet.
These LCD modules are cheap from eBay, Amazon, SparkFun, Adafruit, etc. and sometimes go by the name "Nokia 5110 LCD"
