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 side
2. CS – Free when connected low level, effective long term select chip
3. AO – Connect IO control register selection
4. SDA – Connect IO control data control
5. CLK – Connect IO SPI bus control
6. LED – Free when connecting high level 3.3V backlight always bright
Wired IO standard: (6 IO)
1. RST – Connect IO control LCD control
2. CS – Connect IO control chip select
3. AO – Connect IO control register selection
4. SDA – Connect IO control data control
5. CLK – Hubungkan kontrol IO SPI bus
6. LED – Connect to the IO control backlight off or PWM control brightness
