Circuit Description

This project includes the development and implementation of a custom development board with the NXP TJA1443 CAN-FD chip. The board connects to an Nucleo-64 development board, specifically the Nucleo-32G0B1, to fully exploit the capabilities of the CAN-FD interface.

The main purpose of this project is to utilize the full potential of the NXP TJA1443 chip in a CAN-FD network. By integrating this chip with the Nucleo-32G0B1, we aim to develop and test various protocols within the CAN network, providing a robust platform for CAN-FD communication.

Key Features:

• NXP TJA1443 CAN-FD Chip: High-speed CAN transceiver with advanced features for CAN-FD networks.
• Nucleo-32G0B1 Compatibility: Utilizes the STM32G0 microcontroller with integrated CAN-FD support.
• Custom Development Board: Tailored design for easy integration and testing of CAN-FD protocols.
• Protocol Development and Testing: Focus on creating and evaluating various protocols within the CAN network.

This project provides a comprehensive platform for developing and testing CAN-FD protocols, leveraging the capabilities of the NXP TJA1443 chip and the Nucleo-32G0B1 development board.

Hardware Requirements

To get started with CANShield, you will need the following hardware components:

• STM32 Nucleo-64 Board: The main development board that hosts the STM32 microcontroller.
• CANShield Board: The custom shield that integrates the NXP TJA1443 CAN-FD transceiver, memory, and GPS interface.
• GPS Probe (Optional): A GPS module for applications requiring geographic data.
• Power Supply: Appropriate power supply to power the Nucleo-64 and CANShield boards.

Installation

1. Clone the Repository: Start by cloning the CANShield repository to your local machine.

   git clone https://github.com/MootSeeker/CANShield.git

2. Open KiCad Project: Open the KiCad project files located in the CANShield directory to review the schematics and PCB layout.
3. Assemble the Shield: Assemble the CANShield board according to the provided schematics and Bill of Materials (BOM). Ensure all components are correctly soldered and connected.
4. Attach to Nucleo-64: Connect the assembled CANShield board to the STM32 Nucleo-64 board.

Usage
