XBee RF Transparent and API Mode Demo

Description This Quick Byte includes three spin2 code archives and objects for using Digi XBee Modules in transparent or API packet modes of wireless communication between two Propeller 2 (P2) microcontrollers. Because the P2 may send and receive to itself, the example uses only one P2 Edge Module. For 01_xbee_transparent – Archive.zip we configure two […]

Five Buttons On One Pin

Description This program demonstrates how to series-connect five pushbuttons over one I/O pin, so that they can all be read in parallel by taking an ADC measurement and scanning a threshold table to determine their binary pattern. The program includes automatic debounce, too. This may be accomplished with two resistor values: (5) 150 ohm and […]
Goertzel Operation with Ultrasonic Transducers

Description The P2 Goertzel circuit measures up to four ADC input signals for magnitude and phase correlation of four internal reference signals, which can also be output to form closed-looped systems. In this demo, the Goertzel circuit outputs a reference sine pattern to two DAC pins which differentially drive a 40 kHz ultrasonic transducer. Another […]
