STVI070WT-01 7 inch display TFT LCD module Description:

STONE provides an Intelligent HMI solution. The intelligent TFT LCD module with a Cortex-M4 32-bit CPU can be controlled by any MCU via simple Hex Instruction through the UART port.

STVI070WT-01 TFT LCD module consists of a CPU, TFT drives, flash memory, UART port, power supply, etc. STONE also provides a basic control program and powerful design software (STONE TOOL Box). You can use it to set various functions on the graphical user interface, such as text, figures, curve, image switching, keyboard, progress bar, the slider, dial-up, clock and touch button, data storage, the USB download, video, and audio.

It is very easy for engineers to develop the TFT-LCD color user interface and touch control functions, which can reduce a lot of development time and cost. Widely used as a TFT touch screen controller in many fields, such as industrial equipment, medical equipment, civil equipment, energy project or public transfer system and etc.

What is the meaning of the TFT display model number description?

       A: Taking STVI070WT- 01 as an example:
        STV: Company code
        I: A=Advanced Type     I=Industrial Type     C=Civil Type
        070: TFT Panel Dimension: 7 inch
        W: W=Wide Voltage
        T: T=With Resistive Touch Screen 
        N=Without Touch Screen 
        C=With Capacitive Touch Screen
            0: 0=RS232      4=RS485      1=TTL
            1: Hardware code 

How to develop a STONE TFT display?

1） Use TOOLS 2019 GUI design software to create a customized GUI for your device. 
2） Connect the display with your controller by the UART interface. We provide you a wide range of voltage tolerance, you can connect DC 6-48V power supply, plug, and play.
3） Write a simple program with any language (C/C++/Python or etc) and let your controller send a simple hex command string to our display, to read/write the variable value in the variable memory or register.

1. Can we use Arduino as the controller of the STONE TFT module?

A: Yes. Arduino has the TTL signal pin. You can directly use the STONE display with the TTL interface (please contact our staff to confirm the interface type). Or you can use the MAX3323 chip to converter the TTL signal to the RS232 signal. 

You can check the link to get the specific steps:

2. Can we use Raspberry Pi as the controller of the STONE TFT module?

A: Yes. Raspberry Pi provides build-in/mini UART.

They are implemented using different hardware blocks, so they have slightly different characteristics. However, both are 3.3V devices, which means extra care must be taken when connecting up to an RS232 or other systems that utilize different voltage levels.
