84x84 Nokia 5110 LCD Module (LCD5110) [D055]



https://www.youtube.com/watch?v=PvXZjwpwZQA


*GitHubhttps://github.com/rdiot/rdiot-d055.git


* Specs

Power supply voltage: 2.7V-3.3V,5V is OK,but part of the screen becomes black when tested

Data interface level: 2.7-5V

Backlight power supply voltage: highest 3.3V

Module size: 43.6mm x 43.1mm(width X height)

Installation diameter: 2mm

Backlight: White


Features : 

84 X 84 dot matrix LCD,can show 4 lines of characters

Use serial interface communicate with the master processor,the number of interface signal line reduced greatly, only 8 signal lines including power and GND.Support different types of MCU,such as the SPI,MCS51 serial mode 0 of AVR.Transfer rate up to 4Mbps,can full speed write display data without waiting time.

Can use the conductive glue to connect the module with the printed board,without connecting cable.The metal hooks on the module can fix the module on the printed board,which is very easy to install and replace.

LCD controller/driver chip has been bound to LCD chip,the volume of LCD is small

Low power supply,the working current in normal situation is lower than 200μA,and has power-down mode

// Software SPI (slower updates, more flexible pin options):

// pin 7 - Serial clock out (SCLK)

// pin 6 - Serial data out (DIN)

// pin 5 - Data/Command select (D/C)

// pin 4 - LCD chip select (CS)

// pin 3 - LCD reset (RST)

Adafruit_PCD8544 display = Adafruit_PCD8544(7, 6, 5, 4, 3);


// Hardware SPI (faster, but must use certain hardware pins):

// SCK is LCD serial clock (SCLK) - this is pin 13 on Arduino Uno

// MOSI is LCD DIN - this is pin 11 on an Arduino Uno

// pin 5 - Data/Command select (D/C)

// pin 4 - LCD chip select (CS)

// pin 3 - LCD reset (RST)

// Adafruit_PCD8544 display = Adafruit_PCD8544(5, 4, 3);

// Note with hardware SPI MISO and SS pins aren't used but will still be read

// and written to during SPI transfer.  Be careful sharing these pins!
