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.
If you don’t already have a DrDAQ data logger, you can buy one from Pico or its distributors for only £99 RRP.
