This project demonstrates a multi-channel CAN communication system using three independent CAN modules. Each CAN module communicates through its own transceiver and controls specific GPIO pins based on the CAN messages received. The system operates using interrupt-based CAN message handling and timer-based GPIO relay control for real-time applications.

Three-channel CAN communication with independent transceivers
Interrupt-based data reception for low-latency response
Timer-driven relay update mechanism
Dynamic CAN baud rate selection via external signal
Scalable design allowing easy expansion for additional CAN nodes
Main Flow:
Initialize system peripherals and communication modules.
Configure GPIO outputs for relay control.
Enable interrupt-driven CAN message handling.
Start periodic timer for relay updates.
Monitor input signal for dynamic baud-rate changes.
Interrupt Flow:
CAN interrupt: Triggered on message reception, updates relay data variables.
Timer interrupt: Periodically checks relay data and toggles GPIO states.
This project showcases reliable multi-channel CAN communication integrated with GPIO-based relay control. By combining interrupt-based message handling and periodic relay updates, it provides a robust framework for applications that require multiple CAN networks with synchronized output control.
If you were choose the path to the right, the right path, there are new possibilities, achievement, freedom of mind, positive and progressive implications. Think about that as you stand at this place where the path splits. You want to make a decision and commit to one of these paths. Before you make that decision, we are going to see what each path holds for your future.
The 1-Channel CAN (UDS) Flashing Tool is designed for reliable and efficient ECU programming and diagnostics. Ideal for single-network vehicle communication, it supports UDS protocol for automotive flashing, testing, and firmware updates over CAN bus. Perfect for developers and automotive engineers handling ECU calibration and diagnostics.
The 2-Channel CAN (UDS) Flashing Tool offers dual CAN bus connectivity for advanced ECU programming and diagnostics. It enables simultaneous communication with multiple ECUs using the UDS protocol, enhancing workflow efficiency in automotive development and production testing environments.
