This volume presents the skills needed to build and control devices using the Propeller chip and its parallel processing environment, including how to use each of the identical 32-bit processors, known as cogs, and make the eight cogs effectively interact with each other. The book covers Propeller hardware and software setup, memory, and the Spin language. The author includes step-by-step projects and ready-to-run documented Spin code as well as PDFs of all the schematics that show readers how to: use Propeller I/O techniques with extensive Spin code examples; display numbers with seven segment displays; create accurate, controlled pulse sequences; add a 16 character by two line LCO display; control R/C hobby servos; use motor amplifiers to control small motors; run a bipolar stepper motor; build a gravity sensor-based auto-leveling table; run DC motors with incremental encoders; and run small AC motors.
