Microduino-TFT

Microduino-TFT is the 1.8-inch 128*160 colorful display module based on ST7735, adopting SPI interface and 3.3V power supply.



Features

  • 128×160 color pixel
  • Display images inside the memory card by combining with Microduino-SD module
  • Low voltage drive and low power consumption
  • Adopt 4-wire SPI communication and own its pixel addressing frame buffer
  • Few pin and small memory make it suitable for microprocessor use
  • Open hardware circuit design and Arduino compatible programming development environment

Specification

  • Resolution ratio: 128*160
  • Power: 3.3V
  • Interface: SPI communication and JST_XH connector
  • Pin Description:

Development

The two libraries must be used together.

Application

  • All the hardware needed: Microduino USBTTL, Microduino Core and Microduino TFT;
  • All the software needed: libraries needed in development and Arduino IDE (version 1.0 and higher)
  • Open IDE and choose the board Microduino-Core (Atmega328P@16M, 5V)
  • Basic usage of TFT_ST7735 library example program
    • Put the two downloaded libraries into Arduino IDE installation folder. (Close all the Arduino IDE windows opened before resetting the Arduino IDE.)
    • Text and drawings:
      • You can open your first "graphicstest" test program and meantime, you can connect the wire according the pin description
      • The program can be used to display different color, size and text, and also can be used to draw pictures.
    • Display images inside the memory card
      • Prepare a 128*160 bmp picture and put it into the memory car;
      • Put the memory card into Microduino-SD modules and stack it with Microduino core module;
      • If you want to open the last but one "spitftbitmapt" test program, you need to change "#define SD_CS 4" to "#define SD_CS 7" and meantime, connect the wire according to pin description and then change the name of "bmpDraw("parrot.bmp", 0, 0);".
      • After the compiling, you can upload the program to the core board through Microduino-USBTTL and then you can see the picture displayed on the screen.
