The data reading and display refreshing of all heavy loads are all done independently by FPGA hardware. The architecture features ensure the robustness of the system to some extent. And strong anti-interference performance. Since the FPGA uses a parallel processing mechanism, Nandflash's data reading, SDRAM writing, and RGB data output are all executed under the same clock tick, ensuring fast update of the system image and fast response time. The figure below shows the approximate PCB physical map of the VGA board serial port screen of 8.0"～55".         The device has a 4.7K byte instruction buffer area. The user host can exit the serial port program without waiting and sending multiple instructions continuously. The whole process is simple to operate and the amount of program code is greatly reduced.     Product number DCVGA_01_800*600_RTC Product Series VGA type Core processor* Cortex-M3 + high speed FPGA, dual core processor operating system No operating system, running at power-on, FPGA pure hardware display driver agreement type Large color configuration instruction set (partial upgradeable compatible with MODBUS/Mitsubishi/DGUS) size 8"~55" inch Resolution 800*600 storage 1Gbit Font library Built-in 10MB font, including any size dot matrix ASCII, GBK, GB2312, UNICODE font, can customize any computer font display Picture storage Supports image storage of any size, accumulating and storing about 109 full-screen images colour 65K color, 16-bit RGB Voltage 5-26V (error ± 0.2V) Power consumption 191mA@5V Communication Interface RS232/TTL (factory default 232 level) Interface specification XH2.54-8P Picture download Support USB / SD card / UART, research and development recommended USB, production advice SD download External keyboard not support Real time clock (RTC) Support countdown, timer, year, month, day, etc. Screen effective display area (AA) / Product Size Length × width × height = 119.6mm × 89.0mm × 14.3mm Supporting PC software VisualTFT AV input not support Sound playback not support Video playback not support Ethernet not support WIFI not support   ◆ Product core competitiveness Learning cycle 30 minutes familiar with the development environment, 3 days to complete the human-computer interaction design Program debugging The host computer integrates the "virtual serial port screen", without the need to connect hardware, directly with the Keil IDE and its binding debugging Start Time Run at power-on, no system load time Configuration control Have various configuration controls such as buttons, text, drop-down menu, progress bar, slider, meter, animation, QR code, curve, data record, circular progress bar, etc. System keyboard Built-in virtual number, character keyboard, support Chinese and English input method, customizable keyboard data record Data record control content is not supported for export to SD card Remote upgrade Support user host to remotely upgrade screen firmware or engineering pictures Information push Some models support cloud push video or ad display, or mobile app and screen communication display Layer technology Multiple display layers built into the system for faster switching Multi-language function Up to 10 languages ​​in any country in the world can be preset at the factory, and the required language can be switched with one button.

The user microcontroller receives the serial port command and parses it to determine the action of the current button.     2. Text control             The user pre-sets the display coordinates, color, font and background color of the text in the screen through the host computer. These text attributes are 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 is displayed.     3. Animation control             Enables the user to control the playback, stop, pause, upper and lower frames, and specified frame playback of GIF animations at any time.     4. Icon control             The user can complete different state map switching display at the same position of the screen, for example: heating, cooling state icon switching, mobile phone power change, device WIFI signal strength, ring progress display, and the like.     5. Curve control             The user MCU only needs to send the HEX data sampled by the AD, and the screen will automatically perform the fitting, and the display will be displayed before and after the left and right, without the participation of the MCU; the AD sampling data can also be enlarged or reduced, and then displayed on the screen.     6. Instrument control             The instrument panel is pre-set by the host computer, and the user only needs to send the corresponding value to realize the pointer rotation. If the dial scale is 0-180, the user only needs to send a value of 90 and the pointer will automatically go to the 90 mark.     7. Progress bar control             By setting the parameters of the direction, start value, end value, foreground and background map of the progress bar in advance by the host computer, the user only needs to send the corresponding display value to realize the progress bar increment or decrement.     8. Slider control             The slider's cursor size, scale value, start value, end value, and background image are set in advance by the host computer. 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 controls             The position of the drop-down menu, the menu option, and the corresponding text control ID of the map are preset by the host computer. The user clicks the drop-down icon to automatically pop up the menu option, and clicks the desired menu item. At this time, the data of the menu is automatically entered into the text box, and the screen is simultaneously Upload menu control ID and menu option values.     10.RTC clock control             The screen time display size, position and mode (countdown, clockwise) are preset by the host computer. After the user downloads the project to the screen, the screen automatically starts displaying the time, and the corresponding command can also be sent to start the clockwise or countdown function.     11. Sliding selection control             The slide selection control effect is similar to the time setting of the smartphone. The user pre-fills all the candidate data through the host computer, and then sets the selected and unselected colors, so that the data scroll selection effect is achieved by sliding up and down, and the selected data will upload the corresponding ID and option values ​​to the user microcontroller.     12. QR code control             The user's single-chip direct serial port sends text information to the screen, and the screen automatically draws a two-dimensional code image. The user's mobile phone scan code map can display the input information. The size and algorithm of the QR code can be set in the host computer.     13. Virtual keyboard and input method             The host computer pre-pops the keyboard at a certain position. After clicking the area, the system will automatically pop up the built-in keyboard. After the user selects the Chinese and English input method, click OK. The input characters are all uploaded to the MCU in ASCII code or Chinese character encoding. .        Just 3 steps, 30 minutes to master man-machine development, easy to use!  only needs 3 steps to complete complex human-computer interaction design in 30 minutes. 1. Prepare the artwork.        Arrange the artist to design the picture of the product such as the boot screen, text background, button icon and prompt box. 2. Use the matching Visual TFT software for screen editing, control configuration and image download.        Firstly, the pre-designed art picture is used to interface layout and control configuration, and then the “virtual serial port screen” is used for simulation. Finally, the whole project is downloaded to the serial port internal memory through USB/SD/UART. in. The PC software assigns a unique ID number to each picture, picture, and control in the project. 3. The user's single-chip computer monitors and sends the corresponding serial port command to control the screen display.        After the project is downloaded to the screen, once the button on the screen is pressed, the user MCU serial port will receive the button ID information or coordinate value uploaded by the screen. By parsing the ID number, the user can obtain the screen position and function attributes of the current button, so that the related peripheral action or screen update display can be controlled. For the touchless product, the user's single chip does not need to monitor the information uploaded by the button ID, and only needs to send relevant instructions for screen switching and text picture display.
