void SetContrast(const uint8_t value)

Sets the contrast of the display.

Note

Contrast increases as the value increases.

Note

RESET = 7Fh.

Parameters:

value – [in] contrast to set.

void SetDisplayOn(const uint8_t on)

Set Display ON/OFF.

Parameters:

on – [in] 0 for OFF, any for ON.

uint8_t GetDisplayOn()

Reads DisplayOn state.

Returns:

0: OFF. 1: ON.
