Hello all,
I am having difficulty configuring my DFRobot Firebeetle 2 ESP32-S3 board within PlatfomIO. Originally, I was using the Arduino IDE environment in which I was able to successfully upload my code and print to the serial monitor. The code uses a simple watchdog timer to wake the device from sleep mode and then take a distance measurement using the vl53l5cx sensor before going back to sleep. I had this running successfully at 1-minute intervals. After transitioning to PlatformIO I cannot get any readout to my serial monitor. I tried running a basic ‘hello world’ and nothing printed to the monitor. There are no error messages it just sits there running the task to no outcome. After disconnecting the vl53l5cx sensor and running the same ‘hello world’ script again I was able to print to the serial monitor. Basically, I cannot get any I2C communication and can only get serial communication when the I2C pins are disconnected. Please, please can someone help!!
This is my ini config file:
[env:dfrobot_firebeetle2_esp32s3]
platform = espressif32
board = dfrobot_firebeetle2_esp32s3
framework = arduino
lib_deps =
