Raduino with a different SDR?
|
Jack Purdum
Probably not. The Arduino family just don't have the resource depth or clock speed to do it. Jack, W8TEE

I have a different SDR that has it's own internal sound card circuit. Otherwise, it needs a computer running SDR software...
?
Could that external computer be replaced with a Raduino?

The computer running SDR software could be replaced by a Raspberry Pi 3.

It's quite small. Possibly a Raspberry Pi Zero, depending on what software you are trying to run. Jerry, KE7ER On Thu, Apr 11, 2019 at 05:49 PM, Martin KM6TCD wrote:

The RP is a computer with a 750MHz clock and a mega-munch of memory. That would be a possibility. The Raduino simply is not. Jack, W8TEE

¿ªÔÆÌåÓýThere is piHPSDR too¡ Probably more common.? It¡¯s being used by most for the Radioberry currently. ? ? ? ? ? From: [email protected] [mailto:[email protected]] On Behalf Of Doug W ?

The RasPi has heaps of GPIO too - I'm wondering if the likes of a 'zero' could take some of the 'control ' and display functions from the Raduino? Would/could I^2C tie them? There must be a heap of non-critical stuff not? absolutely dependent on the microprocessor immediacy? A zero-W could give Internet remote ops too! (or has that already been thrashed and trashed?)

Could simply replace the Nano clone on the Raduino with a Raspberry Pi Zero.

Easier to keep all software on one processor, no need to communicate with another processor.? Would need to port the uBitx Arduino sketch over to C on the Pi Zero, but that should be easy enough. A high speed morse keyer might be off by a few milliseconds now and then due to interrupts and Linux housekeeping, but I doubt most of us would notice.

I use gqrx on my Ubuntu laptop. I've written several Perl and wxPerl applications that use the UDP interface to implement various scanner functions. The UDP interface implements a subset of the rigctl protocol. I understand that the RPi should have the add-on heat sinks when running this application. James |
