Firmware for the SAMD21E18A-F microcontroller using Arduino and copied parts of the ASF from Microchip (in lib/asf).
Most of the Arduino functions are available. For reference to all the Arduino functions see https://www.arduino.cc/reference/en.
Besides this we have functions to control the hardware on the Beehive board. See src/hardware.h
Building the firmware files and uploading it to the microcontroller is easy thanks to PlatformIO.
Just install the PlatformIO plugin for Visual Studio Code and open this folder as a project.
On linux you can use the commandline: pio run -e experiment --target=upload should be enough.
A test application is availabel that test the following hardware:
- The coils are turned on for a few millisecond at full power. The sense resistor is read to determin the current.
- The hall effect sensors are read out. It is checked wether a proper PWM in signal is detected
To flash this application on the hardware run pio run -e hardware_test --target=upload.
If you monitor the serial port you should see it sequantially tests the coils and the hall sensors.
