This crates aims to provide the native ST7735 commands in their original form, thus is a low-level library.
A user of this crate should implement the write traits in [crate::spi], then
wrap it with Commands to use the commands. An example can
be found at the examples/stm32f3348_disco directory of the crate.
WARNING: The crate uses two unstable features generic_associated_types and min_type_alias_impl_trait, which unfortunately cannot be totally hidden into the crate itself: the user to implement the [spi] traits also need to explicitly enable these.
