Field Oriented Control (FOC) library for PMSM/BLDC motors on ESP32. Motor driving and torque loop; velocity/position loops are implemented by the application via regulation callback.
This is an ACME client for ESP (ESP32, etc) devices, so your IoT can fetch their own certificate for secure communication. ACME is a protocol (see RFC8555) for automatic certificate management. Sites such as letsencrypt.org allow you to obtain free (no charge) certificates in an automated way using the ACME protocol.
