Communicating with a VESC (Vedder Electronic Speed Controller) can be done through USB or UART, depending on your platform and use case. USB communication is typically used when interfacing with a PC or Raspberry Pi using tools like the VESC Tool or Python scripts. This method is ideal for configuration, monitoring, and testing, as it allows direct access to the VESC's features with minimal wiring—just a USB cable.
For embedded systems like ESP32 or Arduino, UART is the preferred communication method. It involves connecting the VESC’s TX and RX pins to the microcontroller’s UART interface, enabling real-time data exchange and motor control. ESP32 is particularly suited for this due to its multiple hardware serial ports and 3.3V logic, which matches the VESC. When using Arduino (especially 5V boards), a voltage level shifter is recommended to avoid damaging the VESC’s UART.
Each method has its strengths: USB is quick to set up and great for development, while UART is lightweight and perfect for onboard control in robotics or electric vehicle projects.
