+# Pyr0-piezo Beta Unit Firmware Update
+
+The firmware for this project can be updated using one of three methods, VS Code, Arduino IDE, or avrdude.
+
+Please be sure you've already [wired up your sensor's UART port](../../schematics/other/uart-programmer-wiring.md)
+
+## VS Code (Preferred Application)
+
+### Installing dependencies
+
+1. Install [VS Code from Micosoft's official page](https://code.visualstudio.com/download)
+2. Use the "Extensions" menu to install PlatformIO.
+3. (Optional) Install extra plugins to assist in development:
+    - GitLense
+    - markdownlint
+    - Markdown Preview Enhanced
+    - C/C++
+    - C++ Intellisense
+
+### Configuration
+
+1. In PIO Home, open the firmware folder:
+    - `~/pyr0piezo/firmware/AVR-Source/Pyr0_Piezo_sensor_v2.x.x`
+2. Make certain you're on the latest `develop` branch
+    - In GitLense, under the "Repositories" menu, expand the "Branches" menu
+    - Right click on `develop` and select "Switch to Branch"
+    - Back at the top of the "Repositories" menu, hover the mouse over `Pyr0_Piezo_Sensor_v2.x.x` and click first on `fetch`, then on `pull`
+
+### Upload
+
+1. Make any desired adjustments to default values in `src/pP_config.h`
+2. Click the "PlatformIO: Upload" button found in the bottom bar of the VS Code window
+3. Verify Serial connection by opening the Serial Monitor and typing `CONFIG` or `STATE`. You should get a response.
+
+## Arduino IDE
+
+1. Install [Arduino IDE from Arduino's official page](https://www.arduino.cc/en/main/software)
+2. Under File > Preferences > Additional Board Manager URL's, Add:
+    - `https://mcudude.github.io/MiniCore/package_MCUdude_MiniCore_index.json`
+
+## avrdude
+
+#### Windows
+
+1. Install a bash-like terminal. Choose from a number of options:
+    - [Windows Subsystem for Linux]
+    - [CygWin]
+    - [Mingw64]
+    - [Git Bash (Comes bundled with git)]
+2. Download the [avrdude binaries]
+3. Extract the binaries somewhere your terminal can find them
+
+#### Linux
+
+##### Ubuntu/Debian Distro's
+
+```bash
+sudo apt update && sudo apt install -y avrdude
+```
+
+##### Fedora/RHEL/CentOS Distros
+
+```bash
+sudo yum install -y avrdude
+```
