Description Description TFT LCD module has always been one of the hot products in DIY industry and LCD is basically the necessary products during all projects, at the same time, serial port modules are also the popular ones, because it takes few IO and the usage is simple. This section of the 1.8-inch TFT LCD serial SPI integrated features of compact, SPI interface. Feature It is a 1.8 “SPI TFT LCD Screen Module, 9pins interface. Not just a LCD break but include SD card (2GB), The LCD drive ic is ST7735S. It’s a 128 X 160 (resolution). The LCD has a wide viewing angle, the contrast is also very suitable. The display interface is serial, it just needs 5 wires (CS, RS, SCL, SDA, RST) for controlling. SDcard use hardware SPI interface (CS / MOSI / MISO / SCK), Not solder pins. Parameter LED 3.3V IO and Power Supply pin LED UTFT Support SCL Serial clock input SDA/SDI Serial data input DC:Data/Command selection RST:Reset Low level active CS:Chip Selection，Low level active GND:Ground VDD33:3.3V Power Supply pin the most compact cable IO: (minimum 3 IO) 1. RST – Free when connected directly to the microcontroller reset signal side2. CS – Free when connected low level, effective long term select chip3. AO – Connect IO control register selection4. SDA – Connect IO control data control5. CLK – Connect IO SPI bus control6. LED – Free when connecting high level 3.3V backlight always bright Wired IO standard: (6 IO) 1. RST – Connect IO control LCD control2. CS – Connect IO control chip select3. AO – Connect IO control register selection4. SDA – Connect IO control data control5. CLK – Hubungkan kontrol IO SPI bus6. LED – Connect to the IO control backlight off or PWM control brightness
