1.5 Working Principle

The Intelligent TFT-LCD Module communicates with the Customer’s

MCU/CPU / FPGA / PLC via Commands (JSON command and HEX Code), and then the MCU would control its connected equipment to work according to the received commands.

1.6 Operation Processing

Only 3 steps to use our TFT-LCD Module:

Build a GUI project by STONE designer GUI editor with png/jpg/bmp/svg/gif image files.

Connect with customer’s MCU through RS232,RS422,RS485,TTL directly. Plug and play.

Write a simple program for MCU to control the TFT-LCD Module via Command Set.

(JSON code to TFT-LCD Module and HEX Code to Customer’s MCU ).

That’s all.

The communication protocol (customized command set) is built with 2 parts:

Initiative command (MCUàTFT-LCD Module)

Frame head: ST<

Command content: { json }

Frame end: >ET

For example:

ST<{"cmd_code":"open_win","widget":"label_value"}>ET ST<{"cmd_code":"set_value","widget":"label_value",”value”:100}>ET

Important: The text content should be with the quotes(“”), including widgets’ name but the value content shouldn’t be with the quotes, such as value or true/false states.

Passive command (TFT-LCD ModuleàMCU)

Basic command format:

Frame head + CMD + LEN + DATA + Frame tail + CRC16

Example: ST< 0x1068    0x00040x01 0x02 0x03 0x04        >ET CRC16

The TFT LCD module serial port command frame is composed of 5 data blocks, shown as the table 1-1.6. All serial port commands or data are represented with hex format. The data transfer in MSB manner. E.g. for 0x1234, first send 0x12 and then send 0x34.

ESD Guidelines

What does ESD mean?

Virtually all present-day modules incorporate highly integrated MOS devices or components. For technological reasons, these electronic components are very sensitive to over voltages and consequently therefore to electrostatic discharge:

These devices are referred to in German as Elektrostatisch Gefährdeten Bauelemente/ Baugruppen: ºEGBº

The more frequent international name is:

ºESDº (Electrostatic Sensitive Device)

The following symbol on plates on cabinets, mounting racks or packages draws attention to the use of electrostatic sensitive devices and thus to the contact sensitivity of the assemblies concerned:

ESDs may be destroyed by voltages and energies well below the perception threshold of persons. Voltages of this kind occur as soon as a device or an assembly is touched by a person who is not electrostatically discharged . Devices exposed to such over voltages cannot immediately be detected as defective in the majority of cases since faulty behavior may occur only after a long period of operation.

Precautions against electrostatic discharge

Most plastics are capable of carrying high charges and it is therefore imperative that they be kept away from sensitive components.

When handling electrostatic sensitive devices, make sure that persons, workplaces and packages are properly grounded

Handling ESD assemblies

A general rule is that assemblies should be touched only when this cannot be avoided owing to the work that has to performed on them. Under no circumstances should you handle printed-circuit boards by touching device pins or circuitry.

You should touch devices only if

you are grounded by permanently wearing an ESD wrist strap or

you are wearing ESD shoes or ESD shoe-grounding protection straps in conjunction with an ESD floor.

Before you touch an electronic assembly, your body must be discharged. The simplest way of doing this is to touch a conductive, grounded object immediately beforehand ± for example, bare metal parts of a cabinet, water pipe etc.

Assemblies should not be brought into contact with charge-susceptible and highly insulating materials such as plastic films, insulating table tops and items of clothing etc. containing synthetic fibers.

Assemblies should be deposited only on conductive surfaces (tables with an ESD coating, conductive ESD cellular material, ESD bags, ESD shipping containers).

Do not place assemblies near visual display units, monitors or television sets (minimum distance to screen > 10 cm).

Measuring and modifying ESD assemblies

Perform measurements on ESD assemblies only when

the measuring instrument is grounded ± for example, by means of a protective conductor ± or

the measuring head has been briefly discharged before measurements are made with a potential-free measuring instrument ± for example, by touching a bare metal control cabinet.

When soldering, use only grounded soldering irons.

Shipping ESD assemblies

Always store and ship assemblies and devices in conductive packing ± for example, metallized plastic boxes and tin cans.

If packing is not conductive, assemblies must be conductively wrapped before they are packed. You can use, for example, conductive foam rubber, ESD bags, domestic aluminum foil or paper (never use plastic bags or foils).

With assemblies containing fitted batteries, make sure that the conductive packing does not come into contact with or short-circuit battery connectors. If necessary, cover the connectors beforehand with insulating tape or insulating material.
