This repository provides a simple example of using the T-Panel S3 with CAN, showcasing how to interface with the panel using EEZ Studio and LVGL 8.3 for graphical display, how to utilize a CAN DBC file for CAN bus communication and WIFI UDP.
- LVGL 8.3 Integration: This example demonstrates how to use LVGL 8.3 for creating a user interface on the T-Panel S3 by using EEZ Studio.
- CAN DBC to Source Code Conversion: The CAN DBC file is created using Vector CANdb++ and converted into source code using coderdbc.
- Computer Data Monitoring via CAN: The project uses openhardwaremonitor to read computer data (e.g., CPU temperature, load, etc.) and transfer it over WIFI UDP to the T-Panel S3. The panel forwards this data via CAN bus.
- T-Panel S3 (with built-in CANFD support)
- CAN bus setup
- Computer with openhardwaremonitor
- CAN Analyser (e.g PCAN, viewtool, etc.)
- EEZ Studio: Used to create the UI interface for the T-Panel with LVGL 8.3.
- Vector CANdb++: To create the CAN DBC file.
- coderdbc: For converting the DBC file to usable source code.
- openhardwaremonitor: To monitor the computer's hardware parameters and send them via WIFI to the T-Panel.
-
UI Creation:
- Design the graphical interface using EEZ Studio.
- Deploy it to the T-Panel with LVGL 8.3 support.
-
CAN DBC Setup:
- Create the CAN DBC file using Vector CANdb++.
- Convert the DBC file to C/C++ source code using coderdbc.
-
Data Transfer:
- Set up openhardwaremonitor to read system information.
- Send data over WIFI UDP to the T-Panel.
- Forward the data over CAN bus using the generated code.
- Make sure you have openhardwaremonitor installed (and DLL).
- Update TPanel_HwMonitor_EEZ.ino with your WIFI ssid/password.
- Initialize hwmonitor_panel with your WIFI UDP IP and Port.
- Enter the IP address: 192.168.188.75
- Enter the port number: 12345
- UDP Client initialized with IP 192.168.188.75 and port 12345
- Connect your CAN bus analyser (e.g BUSMASTER, PCAN, etc.).
