Running the Demo

Compiling

To compile this example you will need make, avrgcc avr-binutils and the avrlibc. If you are reading this I assume you already have an avr toolchain in place. Also you'll need avrdude to flash your avr.

The makefile takes 3 optional parameters:

F_CPU Clock speed of your controller in Hertz (default: 16000000)
AVRMCU The name of your microcontroller, currently only atmega8 and atmega32p are supported (default: atemga8)
ISPPORT The serial interface for make flash (default: /dev/ttyACM0)

To compile and flash the code run (assuming there is a serial bootloader like optiboot present on your controller):

make
make flash

If you want to run the code on your Arduino try:

make AVRMCU=atmega32p
make AVRMCU=atmega32p flash

Afterwards connect the encoder and start a terminal emulator of your choice on your serial interface. If you start sending newlines to the microcontroller, you should see it respond with measurements in plain ASCII.

You can also run cube_demo.py on this interface if you have PyOpengl and PySerial installed. It might be necessary to change the SERIAL constant on line 16 to the correct interface.

Connecting the encoder

Simply onnect the encoder according to the following table:

AS5043	AVR	Arduino
PROG	GND	GND
DO	PB4 (MISO)	digital pin 12
CLK	PB5 (SCK)	digital pin 13
CS	PB2 (SS)	digital pin 10
MODE	GND	GND
VDD5V	+5v	+5v
VSS	GND	GND
