Pico Technology adds data logging to the Raspberry Pi

Pico Technology’s DrDAQ compact single-board data logger adds 17 I/O channels to your

Raspberry Pi. Now your Linux application can have 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 that you can build yourself.

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 your 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 you to capture data, control the

digital I/O pins, set up the signal generator and drive the LED.
