PropLAB
Explore the Propeller™ microcontroller and it's Spin programming language with PropLAB, a flexible and versatile experimenting board from spinvent. Designed to be easily configured with DIL switches and jumper wires.
PropLAB can be used with the Propeller Labs Fundamentals text, the Propeller Manual and other excellent and readily available material from the Propeller community - and of course it can be used when developing your own code and hardware.

PropLAB Prices:
V1.1 PCB only = £24.00. Solder in readily available parts yourself as and when you want to, (see the Bill Of Materials on this page). Start with a minimum build: Propeller and EEPROM chips, crystal, PropPlug header, reset button/jumper and the voltage regulator components. That's all you need to start programming and communicating with the Propeller. Next you can add LEDs and buttons and learn about basic I/O port control.
V1.1 Complete = £99. Fully populated with Propeller, EEPROM, 5 MHz crystal and ADC chips all in sockets. No XBee module fitted, order separately! PropLAB is assembled to order hence no PayPal button. Please email to order or for more details: info@spinvent.co.uk
Note: to program PropLAB you need a Prop Plug USB to serial adaptor (or other serial interface). Comes with a handful of jumper wires, you can make connections with lengths single core wire.

PropLAB example SPIN code
Resistor-Capacitor discharge time measurement using the Potentiometer
Charge up the built in RC network from a Propeller pin then switching the pin to a high-impedence input, count how long it takes for the voltage to fall below the threshold level. The capacitor is discharging via the potentiometer, enabling the discharge time to be varied. Display the result using the built in 4-digit 7-segment LED display.
Reading analogue voltages using the 2-channel ADC
Connect the SPI signals from the built in MCP3202 ADC chip to the appropriate Propeller pins and display values corresponding to the analogue input voltage (4096 = full scale = 3.3 V approx). Suggest testing with a pot connected to +3.3 V and GND with the wiper connected to CHN0. Value is displayed on the built in 4-digit 7-segment LED display. Other MCP320x driver objects are available, try them out!
Playing a mono WAV file stored on an SD Memory Card
Play a mono WAV file stored on an SD card using Raymond Allen's SPIN WAV player. test .wav file
Reading from a PING ultrasonic sensor
Connect a PING))) sensor to a PropLAB serial header and measure distance. Display the results in mm using the built-in 7-segment display..
