This text is an updated and printed compilation of the Fundamentals labs in the Propeller Education Kit series for the powerful multiprocessing Propeller microcontroller.
With its 8 parallel-processsing cogs, the Propeller chipÎ“Ã‡Ã–s unique design makes a variety of otherwise difficult microcontroller applications relatively simple. For example, processors can be assigned to audio inputs and outputs, mouse, keyboard, TV or LCD display to create a microcontroller based computer system, with processors left over to work on more conventional tasks such as monitoring inputs and sensors and controlling outputs and actuators.
Although the Propeller chip is very powerful, that doesnÎ“Ã‡Ã–t mean it is difficult to use.
The Propeller chip also comes in handy for simple projects involving indicator lights, buttons, sensors, and speakers found in common product designs. You can build examples of these circuits with the Propeller Education Kit and the labs in this book. Once youÎ“Ã‡Ã–ve mastered the basics, you can find additional hardware, accessories and labs at www.parallax.com/propeller.
- Setup and Testing - building your Propeller Platform circuit
- I/O and Timing Basics - techniques for controlling outputs, monitoring inputs, and timing events.
- Methods and Cogs - how to write and call Spin methods and launch cogs. Also covers parameter passing, return values, and setting aside stack space for methods launched into new cogs.
- Objects - How to build and use them to simplilfy multiprocessing, with focus on variable values, I/O pin states, and measurements with the Parallax Serial Terminal
- Counter Modules and Circuit Applications - With counters, any cog can manage two additional processes, simplifying signal monitoring and generation. Example applications include RC decay, infrared object/distance detection, and metal proximity detection. Signals include D/A with duty signals, square waves up to 50+ MHz, and PWM
