Project Overview
The embedded project demonstrates a CAN bus TX/RX communication using ESP32 microcontrollers paired with SN65HVD230 transceivers to demonstrate reliable Controller Area Network communication between embedded devices.
Technical Overview
Steps:
- Two Espressif Systems ESP32 microcontrollers are connected to SN65HVD230 CAN bus transceivers on a compact breadboard platform.
- The SN65HVD230 transceivers provide the physical CAN bus interface required for Controller Area Network (CAN) communication between devices.
- One ESP32 device is configured to transmit CAN data packets across the shared bus interface.
- The second ESP32 device is configured to receive and process incoming CAN bus messages in real time.
- Message transmission and reception demonstrate reliable device-to-device communication and interoperability over the CAN network.
- The breadboard prototype provides a practical demonstration of automotive and industrial communication concepts using low-cost open-source embedded hardware.
Integrated Development Environment (IDE)
The transmitter and receiver programs were both written in C++ using the Arduino IDE.
