  If you want to run the code on your Arduino try:
  ```
- make AVRMCU=atmega32p
- make AVRMCU=atmega32p flash
+ make AVRMCU=atmega32p ISPPORT=/dev/ttyACM0
+ make AVRMCU=atmega32p ISPPORT=/dev/ttyACM0 flash
  ```
 
 Afterwards connect the encoder and start a terminal emulator of your choice on your serial interface.
+Configure it for **38400** Baud, **8** Bit, **N**o Parity and **1** stop bit.
 If you start sending newlines to the microcontroller, you should see it respond with measurements in plain ASCII.
+If your are seeing binary garbage, you either have the wrong baudrate or degree_mode not set to 1.
 
 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.
