As I mentioned in a previous post, I’m attempting to test the ESP32 as a cheap replacement for my current Raspberry Pi and Arduino Mega setup.  I’m hoping that doing this will save me some complexity and money in the long run.

Unfortunately, with the ESP32 being a new processor, there’s not a lot of Arduino support implemented yet.  Neither the ultrasonic sensor or the motor driver libraries compile yet due to unimplemented core functions in the chip library.

Luckily a new version of the ESP-IDF (IoT Development Framework) is set to be released November 30,with the Arduino core most likely being updated a few days later.  This release will implement a lot of the features I need and so I’ll be able to continue testing out the board.  In the mean time I plan on adding more sensors to the Navigation Chassis v0.3 in preparation, as well as working on some other projects.
