# Protofusion ESP32S3 Template

## Configure

Run menuconfig with `idf.py menuconfig` and choose the Protofusion menu option.

Rename the project by editing CMakeLists.txt and change `project(protofusion_template)` to reflect your project name

Note that clean doesn't always clean everything... do `idf.py fullclean` to make sure all generated files are removed (especially when switching processors).

## Build and Flash

```bash

idf.py flash monitor

```

(To exit the serial monitor, type ``Ctrl-]``.)
