Development and debugging

Hardware development platform

Connect the PC to the LM USB emulator via USB, and connect the other end of the emulator to the SECD-7I0B-03 (H) display screen via CAN. Install Huaxing’s dedicated integrated development environment LM Studio on the PC. Complete the construction of the hardware platform. When purchasing products, relevant development and debugging accessories must be equipped at the same time, as shown in the following table:

Software development platform

LM Studio supports application development based on Huaxing’s special LM language, and provides a software platform integrating project management, code writing, compilation, and debugging functions for Huaxing’s controller and display product application development, and improves application development efficiency and quality. With the help of the GUI programming module of LM Studio, users can develop in a graphical manner. They only need to create some controls on the interface and associate these controls with the corresponding variables. At the same time, some LM script programs corresponding to the keys are added to realize what you see is what you get.

LM Studio integrates a large number of mature and easy-to-use component libraries, as follows:

Application examples

Screen compilation
The screen preparation adopts the graphical “what you see what you get” method for development. It includes the following steps:

• Create a new GUI project
• Add GUI controls
• Generate GUI code template

Create a new GUI project
For details, see “Help Content” under the “Help” menu of the LM Studio software.

Add GUI controls
Page control definition

Generate background GUI script code
Double-click the page to automatically generate the background script code corresponding to the page.

Control and communication programming
IO input and output function

• 1-4.3 horizontal screen;
• 2—5.0 vertical screen
• 3—7.0 Portrait
• After the first line is over, press Enter, and write GUILib: V. in the second line. After the second line is over, press Enter to save and exit.

Create three folders, ICON, LIB, and PHOTO under the GUI folder

• LIB folder—used to place font files, the naming of font files conforms to XXXX.DZK (X is Arabic numerals)
• PHOTO folder—used to store picture files, the pictures are converted from the host computer download tool, and the name conforms to XXXX.bmp (X is Arabic numerals)
• ICON folder—used to place icon files

Burning steps

1. Before burning the picture font library, make sure that the bottom layer has been burned. You can open the configuration debugging interface to connect to the code file to observe whether it can communicate. If it fails to communicate, first reset the motherboard and try again.
2. After adding the files to be burned in the U disk according to the second step, connect it to the USB port of the motherboard, and then power on the motherboard.
3. Under normal circumstances, the display screen will start to flash and display burned pictures after a few seconds, and the U disk indicator light will start to flash.
4. If you cannot see the burning process, please make sure to unplug the U disk under the premise that the U disk indicator is not flashing.

Description of environmental indicators

• Working temperature: -20~+65 ℃ Storage temperature: -25~+80 ℃
• Overvoltage protection: 37V
• Vibration resistance: 8.3-400Hz 10mm 6.8g Shock resistance: 50g, 6ms&11ms Relative humidity: 10%~90%
• Protection level: IP65

Connect with external controller

Connect with external controller device via CAN bus, support CAN2.0B, Canopen, J1939 protocol.

Common troubleshooting

1. The connection between the display case and the grounded metal part should have a low impedance value. It is qualified by the following test. When the transient interference is injected, the voltage drop is measured between the controller case and the grounded metal parts. It is required that the voltage Umax on the case should not be greater than 0.8V (TTL low level threshold) during the entire process of interference injection; According to some characteristic parameters during the interference injection, the required ground impedance range is calculated: in the 0-100MHz frequency band, the impedance value shall not exceed 60 milliohms;
2. In addition to the good grounding of the display shell, all input and output points of sensors, loads, etc. connected to the display must be connected in a closed loop, that is, all input and output grounds must be connected to the corresponding ground of the display.
3. The common reasons for unsuccessful burning of picture fonts are as follows:
   • The configuration file does not exist or the content is wrong
   • Wrong naming of the folder to be burned, no burned file or wrong file naming format
   • Problems with the USB flash drive or motherboard
   • The underlying program is not burned or the version is wrong
