Use of cross-compiling in the programming of an intelligent device for measuring electrical quantities

A device for voltage and direct current measurement, built by coupling a Raspberry Pi microcomputer with an Arduino series microcontroller is presented in this paper. The structure of the device is presented and the method of implementing proprietary programs for both devices is described. A touch screen of the device allows the user to decide on the measurement mode (automatic or manual) and on the method of archiving and visualizing the effects of measurements. The application uses the so-called cross-compiling, thanks to which it is possible to effectively couple such different platforms as Raspberry Pi and Arduino.
