True, many of their products ship with firmware already loaded, and they habitually release only precompiled updates for their own good and well-documented reasons. This circuit has been around for 15 years and was originally used a PIC which was programmed in assembly …. It would be very well possible to do SDR processing in the atmega This is hackaday right? With two jumper wires you can easily modify this module to output the I and the Q to any pins on the board.įor those of us who have been around RF for the last 45 years that would be easily understood. However, if you want to graduate to something more practical, try our series on GNU Radio. If you want to learn more about how SDR works, try starting with spreadsheets. That could have led to some interesting possibilities. We peeked at the schematic and the shield is more for letting the Arduino control the radio by changing the oscillator frequency rather than performing the SDR functions. The board is available alone or as part of a kit that includes a book.

The Sibased board uses that oscillator IC to shift RF signals down to audio frequencies and then makes it available to the PC to do more processing. Software-defined radio or SDR means you get the RF signal to digital as soon as possible and do everything else in software. We always thought RF electronics would be immune to that, but the last decade or two has proven us wrong. Music synthesizers? RC controllers? Most likely, all microcontroller-based now.
