Just read about this simple SDR in June's QST mag: https://www.i2phd.org/armradio/index.html
What a neat (and small) project!
@m0puh I converted the code for that to run on an STM32F7 Nucleo board. Was an interesting and insightful experience. You can see some entries on my blog about it g0fcu.com back in 2017.
@g0fcu ooh nice posts, thanks!
I didn’t realise that project had been around for a while, interesting to see it appear in QST so recently.
