All serial screens of Dacai have undergone a series of process reliability tests before mass production: high and low temperature, ESD, group pulse, radiation, touch life and other tests to ensure product quality.
1. Button control
Configure all the buttons in the project screen through the host computer VisualTFT software, without user program involvement, you can achieve screen switching, button press or pop up, button mutual exclusion and custom instruction output; any button in the screen is pressed or When the button is popped up, the screen will upload the ID and state value of the button to the user. The user's MCU receives the serial port command and parses it to determine the current button action.
2. Text control
The user sets the display coordinates, color, font and background color of the text on the screen in advance through the host computer. These text attributes will be downloaded to the screen configuration file along with the picture, and then the user MCU only needs to send characters to the corresponding text ID The data can be displayed.
3. Animation controls
The user can control the playback, stop, pause, upper and lower frames and specified frame playback of GIF animation at any time.
4. Icon control
Realize that the user completes the switching display of different state diagrams at the same position on the screen, such as: heating and cooling state icon switching, mobile phone power changes, device WIFI signal strength, circular progress display, etc.
5. Curve control
The user's MCU only needs to send the HEX data sampled by AD, and the screen will automatically fit, and display the display without the MCU's involvement. It can also zoom in or out of the AD sampled data and then display it on the screen.
6. Gauge controls
The instrument panel is set in advance through the host computer, and the user only needs to send the corresponding value to realize the pointer rotation. If the scale range of the dial is 0-180, the user only needs to send the value 90, and the pointer will automatically turn to 90 scale.
7. Progress bar control
Through the host computer to set the direction, start value, end value, foreground and background image and other parameters of the progress bar in advance, the user only needs to send the corresponding display value to realize the progress bar increase or decrease.
8. Slider control
The upper computer sets the slider's cursor size, scale value, start value, end value, and background image in advance. When the user drags the cursor or clicks on a scale, the device will immediately upload the current cursor position value.
9. Drop-down menu control
The position of the drop-down menu, menu options, and the corresponding mapped text control ID are preset through the host computer. The user clicks the drop-down icon to automatically pop up the menu options and click the desired menu item. At this time, the menu data is automatically entered into the text box, and the screen Upload menu control ID and menu option value.
10. RTC clock control
The screen time display size, position and mode (countdown, countdown) are pre-set by the host computer. After the user downloads the project to the screen, the screen will automatically start to display the time, and the corresponding command can also be sent to start the clockwise or countdown function.
11. Slide selection control
The special effect of sliding selection control is similar to the time setting of a smart phone. The user pre-fills all the candidate data through the host computer, and then sets the selected and unselected colors, so that sliding up and down realizes the effect of data scrolling selection. The selected data will upload the corresponding ID and option value to the user's MCU.
12. QR code control
The user's MCU directly sends text messages to the screen via the serial port, and the screen automatically draws a QR code image. The user's mobile phone scans the code map to display the entered information. The size and algorithm of the QR code can be set on the host computer.
13. Virtual keyboard and input method
The host computer sets up a pop-up keyboard at a certain position on the screen in advance. After clicking this area, the system will automatically pop up the built-in keyboard. After the user selects the Chinese and English input method, click OK, and all the input characters are uploaded to the microcontroller in ASCII code or Chinese character encoding. .
14. Audio controls
Supports volume adjustment, play, pause, stop and switch display by sending instructions.
15. History curve control
The system combines the collected data uploaded by the user with the current screen time and displays it in the interface coordinate system. Users can view all historical curve records through the scroll bar.
16. Data logging controls
It is convenient to record the operating status, alarm or release time of the equipment. As the amount of information increases or is deleted, the table will automatically be displayed in a zoomed out. Users can also directly export the records to an external SD or U disk.
17. Multilingual
When configuring the UI interface, more than 10 multi-language languages ​​can be preset, and the required language types can be switched through different instructions to reduce the redundant redundant design of art.
"Virtual Serial Screen"
The first domestic launch: the same simulation simulator as the real hardware, no need to buy samples, bind and debug with KEL
Only need 3 steps, 30 minutes to master human-machine development, easy to use!
Any big lottery user only needs 3 steps to complete the complex human-computer interaction design in 30 minutes.
1. Prepare art materials.
Arrange artists to design the pictures required for the product such as the startup screen, text background, button icons, and prompt boxes.
2. Use the matching VisualTFT software for screen editing, control configuration and picture downloading.
First, use the VisualTFT software of the matching host computer to layout the pre-designed artwork pictures and configure the controls, then run the "virtual serial screen" for simulation, and finally download the entire project to the internal memory of the serial screen via USB/SD/UART in. The PC software will assign a unique ID number to each screen, picture and control in the project.
3. The user MCU monitors and sends the corresponding serial port command to control the screen display.
After the project is downloaded to the screen, once a button on the screen is pressed, the user's MCU serial port will receive the button ID information or coordinate value uploaded on the screen. By parsing the ID number, the user can obtain the screen position and functional attributes of the current button, so that it can control the actions of related peripherals or update the screen. For non-touch products, the user's MCU does not need to monitor the information uploaded by the button ID, and only needs to send relevant instructions to switch screens and display text and pictures.
Host computer software introduction / VisualTFT
Visual TFT is a powerful serial port screen development and debugging software independently developed by our company, embedded with the first domestic exclusive "virtual serial port screen". After the user creates a new project, import the designed artwork picture, and then configure the buttons and other controls in each screen. After the simulation is correct, finally download the entire project to the serial screen.
Common functions of the software are as follows:
(1) The IDE environment is user-friendly and the interface is beautiful and generous; built-in font generator and Lua script compiler;
(2) The software integrates vector graphics such as commonly used icons, buttons and keyboards to reduce the difficulty of artwork;
(3) The screen supports common operation functions such as image zoom, text editing and element copy;
(4) After the project is compiled, a unique ID is assigned to each screen, picture and control;
(5) Built-in command debugging assistant, convenient for PC to directly debug the serial port screen, and quickly grasp the command operation;
(6) Embedded "virtual serial screen" analog emulator, directly bound to KEIL debugging, no need to download the picture every time the project picture changes;
(7) Support binary file burning, mass production is more convenient and safe;
(8) Customize special PC software functions according to user needs;
