Software Based AFSK Generation on Arduino
L. Velasco, Andres Roldan Aranda · 2018
Master courses need to have a practical element, applying already known concepts to concrete problems. In this paper, the design and manufacturing of a radio link using APRS protocol over AX.25 will be presented as coursework during several lab sessions. The aim is to create a system that is able to poll data from several sensors and send them wirelessly with a software implemented signal generator in a microprocessor.
