Firmware (Teensy)

A Makefile and Arduino project for building the Teensy Fan Controller firmware. Sources are contained in the teensy_fan_controller sub-folder.

The Makefile and project structure is based on Teensy 3.X Project Template.

Usage (Makefile)

1. Prepare the project (once), as described in Project Setup

2. Enter the teensy_fan_controller directory:

    cd teensy_fan_controller

3. Compile from source:

    TEENSY=35 make

Makefile generates a Teensy 3.2 build by default, you may use a different Teensy by setting the TEENSY variable (either 30, 31, 32, 35, or 36).

1. Upload to Teensy 3.x:

     make upload

Firmware Make targets:

• make alias for make hex

• make build compiles everything and produces a .elf

• make hex converts the elf to an intel hex file

• make post_compile opens the launcher with the correct file

• make upload uploads the hex file to a teensy board

• make reboot reboots the teensy

Usage (Arduino Studio)

1. Prepare the project (once), as described in Project Setup

2. Copy teensy_fan_controller/libraries/nanopb into your user's Arduino libraries folder (fe. ~/Documents/Arduino/libraries/)

3. Copy teensy_fan_controller/libraries/PID into your user's Arduino libraries folder (fe. ~/Documents/Arduino/libraries/)

4. Launch Arduino Studio, and open project teensy_fan_controller/src/src.ino

5. Set Tools > Board to your Teensy board using the top menu

6. Set Tools > USB Type to Raw HID using the top menu

7. Build and upload firmware using Sketch > Upload, or by clicking the Upload button in the toolbar

Folder Structure

After the project is prepared, the teensy_fan_controller/ folder has the following structure:

• teensy3 sub-folder is taken from The Teensy 3 Cores

• tools sub-folder is taken from Teensyduino

• src/src.ino contains the loop() and setup() functions, called by teensy3/main.cpp

• src/*.{ino,c,h,cpp} Teensy Fan Controller sources

• Makefile file, copied and modified from teensy3/Makefile

• 49-teensy.rules file is taken from PJRC's udev rules
