Before you start, you will need to setup the Ubuntu the same way we did in Lab #6, so that you are in the root folder of ubuntu, logged in as root, and you have copied your environment from the USB stick to your Ubuntu root account.
Input/Output PC to Arduino: Part I
In this first part you will enter commands at the Linux prompt to set the Arduino LED 13 On and Off, or to read the status of various pins.
Don't miss the presentation that will be done in class. We'll go over the 3 programs involved in today's lab.
The Arduino program: arduino_loop.pde
- First take a close look at the program that runs on the arduino: arduino_loop.pde, whose code is available here. Notice how the loop function continuously store incoming characters in the buffer until a \n character is found, in which case the contents of the buffer is analyzed, the command identified, and executed.
- Cut and paste arduino_loop.pde in the arduino GUI on your Ubuntu machine.
- Compile it.
- Upload it to the Arduino.
The C-Program running on the Ubuntu: arduino-serial.c
- Take a close look at arduino-serial.c . It is the program running on the Ubuntu PC/laptop. You should copy/paste it into an emacs window and save it to your
