Compile and flash the PhoenixSketch firmware to the T41 radio (Teensy 4.1). Use when the user wants to build, compile, upload, or flash the production firmware to the radio. Requires the radio connected via USB at /dev/ttyACM0.
Install with Codex or Claude Copy this prompt, paste it into Codex, Claude, or another assistant, and let it review the skill page and install it for you.
Based on SOC occupation classification
Compile the PhoenixSketch production firmware and flash it to the Teensy 4.1 radio over USB. Use when the user asks to build, compile, upload, flash, deploy, or program the radio / Teensy / Phoenix firmware.
Compile and run the PhoenixSketch unit tests under code/test using CMake + Google Test. Use when the user asks to run, build, or check the unit tests / ctest / Google Test suite for the radio firmware.
Measure execution time of functions or code regions in the PhoenixSketch firmware by instrumenting the source with Flag() calls and capturing the resulting pin transitions on an Analog Discovery 2. Use when the user wants to profile, time, benchmark, or characterize how long a piece of radio code takes to run.
Run the PTT signal integrity test on the radio transmitter hardware. Use when the user asks to test the transmitter, run a PTT test, check I/Q outputs, or verify transmit signal quality. Requires an Analog Discovery 2 connected to the radio.

Compile the PhoenixSketch Arduino firmware and upload it to the Teensy 4.1 via USB.
From code/.vscode/arduino.json:
code/src/PhoenixSketch/PhoenixSketch.inoteensy:avr:teensy41usb=serial2,speed=600,opt=o1lto,keys=en-us)ArduinoOutput/ (repo root)/dev/ttyACM0ls /dev/ttyACM*
If /dev/ttyACM0 is absent, the radio is not connected or not powered on. Stop and tell the user.
Run from the code/ directory:
cd /home/oliver/Sync/Ham/T41/Software/Phoenix/code && \
arduino-cli compile \
--fqbn "teensy:avr:teensy41:usb=serial2,speed=600,opt=o1lto,keys=en-us" \
--libraries lib \
--output-dir ../ArduinoOutput \
src/PhoenixSketch/PhoenixSketch.ino
--libraries lib adds the in-tree code/lib/ directory (which holds
the Phoenix-owned forked libraries, e.g. RA8875_DMA) to arduino-cli's
search path.
Expected memory report on success (approximate):
FLASH: code:~287KB free for files:~7.7MB
RAM1: variables:~127KB free for local variables:~102KB
RAM2: variables:~300KB free for malloc/new:~224KB
If compilation fails, report the full error output to the user and stop — do not attempt to upload.
--compile-only was passed)arduino-cli upload \
--fqbn "teensy:avr:teensy41:usb=serial2,speed=600,opt=o1lto,keys=en-us" \
--port /dev/ttyACM0 \
--input-dir /home/oliver/Sync/Ham/T41/Software/Phoenix/ArduinoOutput \
/home/oliver/Sync/Ham/T41/Software/Phoenix/code/src/PhoenixSketch/PhoenixSketch.ino
A successful upload ends with the Teensy rebooting and the radio display restarting.
