Useful command to control LCD1602

Provided Methods

fn toggle_display(&mut self)

toggle entire display on and off (it doesn’t toggle backlight)

fn write_char_to_cur(&mut self, char: char)

write char to current position In default implementation, character only support from ASCII 0x20 (white space) to ASCII 0x7D (})

fn write_str_to_cur(&mut self, str: &str)

write string to current position

fn write_byte_to_pos(&mut self, byte: u8, pos: (u8, u8))

write a byte to specific position

fn write_char_to_pos(&mut self, char: char, pos: (u8, u8))

write a char to specific position

fn write_str_to_pos(&mut self, str: &str, pos: (u8, u8))

write string to specific position

fn write_graph_to_cur(&mut self, index: u8)

write custom graph to current position

If you write 5x11 Font graph, but only want to access upper part of the graph in 5x8 Font mode,
you will need to shift index one bit left to get correct graph.

fn write_graph_to_pos(&mut self, index: u8, pos: (u8, u8))

write custom graph to specific position

If you write 5x11 Font graph, but only want to access upper part of the graph in 5x8 Font mode,
you will need to shift index one bit left to get correct graph.

fn offset_cursor_pos(&mut self, offset: (i8, i8))

change cursor position with relative offset
