Yes. Will do.
No problem. Sorry it has taken so long to get the two-tone stuff written. Note that there is a new fw release 1222-02. This version fixes a bug that was causing the reported two-tone index to be off by 1 in many cases. This release not only fixes that, but every index value has been validated with signal generators. The two-tone decode is accurate and the measured error is well within limits. I believe you will find the decodes to be very accurate starting with this release.

I've had the micro for a month now. Still going strong and loving the updates. Two tone works great. Todd, I did not see any reference in the global config section you must be working on that part yet. Anyone who does not try a micro Wio Terminal is wasting time with their current P25 receiver. No this is not a full blown "scanner" not everyone wants or needs a scanner. Keep up the great work Todd and Happy Holidays!
Thank you and have a merry Christmas! I haven't finished the two-tone stuff yet. It decodes the two-tones and displays them very well now. It appears to be very solid. The next steps for configuration are in progress, but not finished. btw, you can scan multiple P25 systems with several different modes to choose from, but not a "full blown" scanner as you said. Glad to hear you are enjoying it.
Have a great holiday everyone!

The Wio has serial pins 8 and 10. All the MicroP25RX Wio Terminal code is open source. You could use the Wio to send the info out the serial pins. Learn a bit of Arduino coding and make it do what you wish.
This is the SPI interface interrupt handler code (SERCOM_2_Handler) that handles SPI serial incoming data from the MicroP25RX to the Wio (5 Mbps clock rate)
github.com
The interrupt handler populates a data typedef called metainfo defined here:

That should get you started. You could easily implement alternative hardware to the Wio using the SPI port of another device.

Trying to avoid the Wio. BTT answered the question in #930.

Yes, my friend he did. Multiple ways to use the MicroP25RX. Looking forward to seeing your SPI project.

@FreqNout here is a quick test of your serial solution using the Wio Terminal TTL pins 8 and 10. The Wio is connected to Windows 10 (com4) via a TTL to USB adapter. I am sending the MicroP25RX "TGHistory" lines in real time to a Windows terminal program (Termite) in this simple test. These needs more work and I have a few ideas on using the Windows program Processing (here) to create a MicroP25RX Windows Display/Control. I will post more when I do more testing. Your Wio Terminal serial port solution is a great idea. Merry Christmas to all!
It does do this now, but sometimes a little bit of buffered encrypted audio gets out. I will add code to clear the audio buffer as soon as encrypted audio is detected.
P1 or P2?
