Load arduino and Teensyduino
Install Arduino version 1.8.19 for the platform, find it here https://www.arduino.cc/en/software
Unpack in the Downloads directory (to fit the path in the Makefile)
cd ~/Downloads tar -xf arduino-1.8.19-linuxaarch64.tar.xz
Install Teensyduino from https://www.pjrc.com/teensy/td_download.html
Make the installer executable and install it on top of the Arduino installation.
chmod +x TeensyduinoInstall.linuxaarch64 ./TeensyduinoInstall.linuxaarch64
Additional Arduino libraries
Additional libraries from Ardufruit are needed for the small display:
- Adafruit_BusIO to get additional services from the I2C interface
- Adafruit-GFX-Library to get the paint functions for the display
- Adafruit_SSD1306 to get the specifics for the used display
git clone https://github.com/adafruit/Adafruit_BusIO.git git clone https://github.com/adafruit/Adafruit_SSD1306.git git clone https://github.com/adafruit/Adafruit-GFX-Library git clone https://github.com/pfeerick/elapsedMillis.git
The obtained libraries should be included in the Arduino/Teensyduino library list, e.g. if the GIT repositories are in a ~/git directory:
cd Arduino-1.8.19/hardware/teensy/avr/libraries ln -s ~/git/Adafruit_BusIO ln -s ~/git/Adafruit-GFX-Library ln -s ~/git/Adafruit_SSD1306 ln -s ~/git/elapsedMillis
Compile and upload
Compile and upload to Teensy
cd ~/scorpi/motor_drive make
This should produce a file called motor_drive.hex ready to be uploaded:
NB! before you upload, press the power reset button, to avoid power shutdown.
Press had hold "power reset" make upload Release "power reset" when "alive" LED starts blinking
Raspberry 5
Compiling motor drive on the Raspberry 5 failed in one of the Teensy libraries.
This was fixed by renaming a few files in the library:
cd ~/Downloads/arduino-1.8.19/hardware/teensy/avr/libraries/USBHost_t36/ mv BluetoothConnection.cpp BluetoothConnection.cpp.not mv bluetooth.cpp bluetooth.cpp.not mv joystick.cpp joystick.cpp.not
It was probably in the Bluetooth part, but I failed to remove Bluetooth from joystick.cpp, so all USB-host joystick support has gone.
No joystick is OK for this project.
The code compiles but does not run! The same code runs fine when compiled on a normal Ubuntu.
