Introduction

1.8-inch TFT color screen module designed for Arduino UNO, with a resolution of 128x160 pixels, a microSD card slot and a five-way switch. Compatible with STM32. It can be directly plugged into Arduino UNO R3, STM32-Nucleo development board, or other development boards with UNO R3 standard interface.

In order to solve the problem of Arduino's tight number of GPIOs, the five-way switch uses an analog ADC button and only occupies one ADC interface.

This module is compatible with Adafruit's 1.8'' TFT Shield v1

This module is for sale in my Xianyu store. If you don’t want to make it yourself, you can buy it directly. Taobao password:

characteristic

• 1.8-inch 65k color TFT color display, resolution 128x160, SPI interface
• Specifically designed for Arduino UNO, but compatible with all development boards with standard UNO R3 interface
• The level conversion chip ensures that the module can work at 5V (Arduino) and 3.3V (STM32 or other) levels
• A MicroSD card slot
• A five-way switch, connected using ADC analog button, occupying only 1 IO (ADC interface)
• Additional reset button
• There is another set of IO interface pads reserved on the expansion board. You can manually weld pin headers or female headers to expand the IO interface.

Precautions

• When used in a 5V system, during initialization, regardless of whether a microSD card is used or not, the Arduino pin (D12) connected to the MISO signal of the microSD card should be set to input mode at the first time. It is strictly prohibited to set the D12 interface to output mode and output 1 (high level), which may damage your microSD card. code show as below:

void setup(void) {
  pinMode(12,INPUT); // Set SD's MISO IO State, VERY IMPORTANT!
  // ---Other codes below---
}

• The screen can use Zhongjingyuanjia’s 1.8-inch plug-in screen module. Other components can be purchased directly from the Lichuang Mall according to the BOM.
• The driver code can directly use the Adafruit library. Just search for "adafruit st7735" in the Arduino library.
