Reader device for custom special vehicles
Project at a Glance
Our client goal was to create a device that deals with custom special vehicles. In order to filter out some special CAN messages from vehicles a CAN bus reader device was developed for a testing purpose. This device can filter out CAN messages and save them in a USB flash drive. CAN bus reader devices can read the data of a CAN bus from medium and high speed CAN bus systems of different vehicles.
THE CHALLENGE
- All CAN bus messages were not required by the client for special vehicles.
- High cost of maintenance and software development
- Filtered CAN bus messages need extra storage.
Technological Selection
After conducting extensive research on various technology stacks it was decided to use Hardware ARM Cortex M0 based Microcontroller, for Software Development C/C++ were used. We used CAN, RS232, SPI I2C, CANvas tool and Wireshark.
SOLUTION IMPLEMENTATION
We started working on the firmware of a CAN bus reader device. After successful implementation we have started doing testing as this device was able to read CAN bus data from medium and high speed CAN bus systems of different vehicles. The device was able to filter specific messages and save into flash drives.
