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.

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 programing development environment

TFT pin	Microduino pin	Function
BL	Microduino digital interface/3V3	Backlight control
RST	Microduino digital interface /RST	Screen reset
DC	Microduino digital interface
MOSI	11	Data output pin
SCK	13	SPI clock
CS	Microduino digital interface

The two libraries must be used together.

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/zh and then you can see the picture displayed on the screen.
