HOW TO USE STONETECH STVC035WT-01 INTELLIGENT TFT LCD MODULE WITH ARDUINO

Displays have over time, emerged as one of the best ways to drive user interactions on any device. They make it easy to collect inputs and present information (outputs) to users in a graphical, easy to understand format. This usefulness has led to improvements in their quality, with improved resolution and low power features, but almost little has changed when it comes to the complexity of creating beautiful user interfaces for them. This is why the team at STONE Tech created the STVC035WT-01 intelligent Smart display which we will explore for today’s tutorial.

The STONE STVC035WT-01 display is a 16-bit, 3.5″ display with a 320×480 (RGB) resolution, has a 49.0 x 73.4mm viewing area, and pixel spacing of 0.1905mm×0.0635mm (H×V). The display is a Class A industry Panel with an Industry level 4 wire resistance based touch screen, all layered on an integrated CPU, driver, and flash memory with several communication interfaces to enable it to connect to data sources like microcontrollers. For communication with a microcontroller, the display supports serial communication protocols like UART/TTL, RS232, and RS485, ensuring it can communicate with any kind of microcontroller or industrial computers. The UART/TTL pin on the Display supports both 3.3v/5v logic level which adds another layer of ease to the use of the display as users need not worry about the need for logic level shifters when building using a microcontroller that operates on either of the voltage level mentioned.

A summary of the features and specification of the display are shown below:

  • Cortex m4 CPU
  • UART interface (RS232/RS485/TTL) ;
  • ¬†256-byte register;
  • 128 kb variable memory;
  • 128 MB flash memory, expandable to 1 GB;
  • GUI design software;
  • ¬†A customized command set;
  • 8-channel curve trend chart memory;
  • ¬†extremely fast variable display response speed;
  • A single-page supports up to 128 display variables;
  • Integrated real-time clock RTC,
  • Touch buzzer sound function;
  • Support software 90 degrees, 180 degrees, 270 degrees screen rotation, adjust the appropriate visual Angle;

One of the major benefits of using this display is its compatibility with the STONE TOOL GUI Designer which allows the development of User Interfaces in a fast and easy manner.

To demonstrate the capabilities of the display, we will build a heart rate monitor using an Arduino Uno with the MAX30100 pulse oximetry and heart rate sensor. The Arduino will serve as the brain of the project and perform the simple task of obtaining the heart rate and blood oxygen data from the MAX30100, displaying it on the screen.

At the end of this tutorial, you would know how to interface Arduino boards with the STONETech displays, and also how to interface sensors like the MAX30100 with the Arduino.
