Now your Linux application can have access to a 100kHz oscilloscope, arbitrary waveform generator, four digital I/Os (two 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 three 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.
