5110 Display

Main Features

84x48 dot matrix LCD, can display four lines of Chinese characters,

use a serial interface to communicate with the host processor interface significantly reduce the number of signal lines, including power and ground lines, including the signal is only 9. Support for multiple serial communication protocols (such as AVR MCU SPI, MCS51 serial mode 0, etc.), transfer rate up to 4Mbps, can write at full speed display data, no waiting time.
can be connected by a conductive adhesive to the printed version of the module, rather than connecting cables with a metal hook on the module the module to the PCB, which makes it very easy to install and replace.
LCD controller / driver chip has been bound to the LCD chip, module size small.
the use of low-voltage power supply, the normal operating current when displayed in 200μA or less, and has a power-down mode.

LPH7366 These characteristics are very suitable for battery-powered portable communications equipment and test equipment

Documentation

Technical Part

LcdWrite( LCD_CMD, 0xBf ); // Set LCD Vop (Contrast). Set the constrast value in the codes, to B4 which is from 191 to 180 in decimal, and the contrast will be much better

Pin definition

RST - Reset
CE - Chip Select
DC - data / instruction selection
The DIN - serial data line
CLK - Serial Clock Line
3.3V - positive power supply
LIGHT - backlight control
GND - negative supply
