About¶
CAN Reader is app developed specifically for for Formula student team FS Tul Racing.
The application was developed as part of a bachelor’s thesis.
Created system collects data from the CAN bus and sends them via Wi-Fi to the user for further processing and visualization.
A graphical representation of the system is shown below.
The user can choose from two methods of data transfer:
- Formula -> User
In this variant, the formula communicates directly to the user’s PC via Wifi.
The advantage of this is the higher transmission speed and simplicity of connection.
The disadvantage of this is the relatively limited range.
- Formula -> ESP32 -> User
In this variant, the formula communicates with an intermediate member (ESP32-based device), which transmits the received data to the application via a serial port.
The advantage of this is a huge increase in range (theoretically over 1 km).
The disadvantage of this method is the limited transmission speed (250 kb/s) and the need for additional equipment.
