Best Tool to Troubleshoot ESP32 GPIO Pin Trigger Issue in FreeRTOS Project?
Hi guys I'm currently working on an ESP32-based home automation project where I'm integrating several sensors and using the FreeRTOS framework. The project involves controlling various GPIO pins for different sensors and modules. However, I'm encountering an issue where the enable pin on my ESP32 board is not triggering as expected. Specifically, I receive the error message "GPIO_HIGH error: Pin not set" in my serial monitor when trying to set the pin high.
I've tried manually setting the pin state through the GPIO registers, but no success so far. Which tool should I use to troubleshoot this issue: ESP32 GPIO Analyzer, Logic Analyzer, or Multimeter?

Solution
One way to solve this is to put a pull up resistor at the enable pin, it helps hold the MCU at a high state.
