News - General T&MData Logging Functionality for Raspberry Pi04 September 2012 - Pico Technology’s DrDAQ compact data logger can add 17 I/O channels to the single-board computer Raspberry Pi. Using a Linux application this gives users access to a 100 kHz oscilloscope, arbitrary waveform generator, 4 digital I/Os (2 with pulse-counting input and PWM output), 24-bit RGB LED, built-in light sensor, temperature sensor, microphone and sound level sensor, resistance measuring input and pH/redox sensor input. There are also 3 inputs for Pico’s own sensors or for custom devices. DrDAQ requires just a single USB connection for power and data. When connected to the Raspberry Pi single-board computer, DrDAQ forms a powerful data logging system that can be integrated into a custom Linux application. Pico Technology has released a Debian driver and C++ example code for free download. The example code displays a simple text menu that allows to capture data, control the digital I/O pins, set up the signal generator and drive the LED. The driver and example code, and the latest Raspberry Pi news can be found on the Pico website. www.picotech.comRelated Articles: |
