Expand description

Useful commands to read data from the LCD

Provided Methods§

Source

fn read_byte_from_pos(&mut self, pos: (u8, u8)) -> u8

read a byte from specific position

Source

fn read_graph_from_cgram(&mut self, index: u8) -> CGRAMGraph

read custom graph data from CGRAM

We always read graph data as Font 5x11 mode,
user will take response to check whether the second part is needed.
