ESP32 Can communcation issues
Posted: Tue Aug 20, 2024 3:14 pm
Hello everyone,
We recently purchased an OpenInverter board and an ESP32 WiFi module from the shop to run a Tesla SDU motor. However, we're facing an issue that we haven't been able to resolve.
Problem :
As soon as the motor is ready to run (right after the brake check and selecting forward mode), the ESP32 stops communicating with the STM, resulting in a communication error on the interface. Despite this, the motor continues to run, but we lose the ability to monitor it in real-time.
What We've Tried :
- Reflashing both the STM and ESP32 with the latest firmware.
- Running the system with only the two cards on the CAN bus, using a single termination (as there is already one present on the OpenInverter SDU card).
We would greatly appreciate any help or suggestions on how to solve this issue. Thanks in advance for your advice !
