I'm seeking an experienced C developer familiar with the ESP32 microcontroller and esp-idf. The primary task for the chosen contractor will be to implement a feature that allows the ESP32 to collect data from an HC-SR04 sensor. Use the given example: [login to view URL] Modify the example in a way that it allows multiple HC-SR04 sensors. Use one common trigger pin and up to 4 echo pins. Use the hardware capture features, do not change it to GPIO Interrupts / ISR routines. Use a task and notify-task or a queue. Trigger once per second, output measured distance in cm for each sensor via ESP_LOGD Environment: ESP-IDF-Version 5 C, no C++ ESP32 wrover Completion after submitting the c file and successful test on my side
