Setup

1. install Platrorm IO for Visual Studio Code
2. install USB to UART driver
3. create a new project selecting
   • board: Adafruit ESP32 Feather (featheresp32)
   • framework: arduino
4. setup the communication parameters into the platform.ini configuration file

[env:featheresp32]
platform = espressif32
board = featheresp32
framework = arduino
upload_port=COM4
monitor_speed=115200
monitor_flags = --raw

Visual Studio Code

• To run a separate instance of Visual Studio Code use Ctrl-Shift-N

Tools

• Online Tone Generator

Hardware
