Re: SCU-17 Behind The Raspberry Pi?
I am running on a Pi4.?? People are saying it should just magically "work" on a pi4? but I am having no such luck.? I just cannot get the pi 4 to talk to the SCU 17 no matter what settings I use.? I need to see what settings people have for this

Re: SCU-17 Behind The Raspberry Pi?
Which Pi are you using?? If it's the Pi5 the software may not be compiled for it. Pi5 changed the address of the GPIO due to using a separate chip. The GPIO libraries that run on the older Pi's won't work on the 5. Until the developers update the SW to work with the 5, they need to be run on a Pi4 or earlier

Anyone??? It looks like there are plenty people are saying that they can successfully make the SCU-17 with Raspberry Pi, but I'm really struggling to make it work.? I am having no such luck.? Could anyone please show what settings they are using to get CAT control to actually work??? The sound isn't an issue, it's the CAT control I cannot get to work.

Re: Seqence of Events on RPI with Pi-Star
Hi Norm,
?
To answer your curiosity about how the system works, both the operating system and the Pi-Star software are on the card; the image that you download as a special copy of the operating system that's been set up with the software installed and ready to start up automatically.
?
Like most computers, a Raspberry Pi has just enough system installed in its firmware to find and load the main operating system from storage - in our case the SD card. This bit in the firmware is called a boot loader, from the nonsensical? idea in an old story of a mountaineer getting up a cliff by grabbing hold of their bootstraps and pulling themselves up into the air.

Re: Seqence of Events on RPI with Pi-Star
Sorry….. ?no you don’t need to change data on the Nextion screen! All the images are pre-loaded and will automatically change on the detected transmission or mode or modes you have selected. It’s a one shot deal really and once programmed you never need to touch the Nextion screen again……
|
The link to Nextion editor and background HMI files. IMPORTANT….. HMI files require compiling first. Duplex or simplex frequencies also need inputting too before you compile (they don’t actually do anything other than tell you the frequency for reference).?
?This is the screen I’m using?
See the duplex frequencies are pre-set!
?You will also need to decide if your MMDVM is private or public but private requires you to setup the DMR ID’s for example for access. Public is a security risk and wide open but it’s up to you and if you are portable or remote location then you may wish to use public.
? ?So just to recap. Radio modem type mine is MMDVM_HS_Dual_Hat Pi GPIO
Modem baud rate : 115200
MMDVM display type : Nextion (enhanced w/driver, attached to modem)?
Port: Modem
Layout type: G4KLX?
Host name, callsign, DMR/CS7 ID, NXDN ID, radio frequency Tx, radio frequency RX, system time zone, dashboard language ….. are all personal to you and only you will have that information.
Same with longitude and latitude, town etc.
If you want to use with DMR then just flick the DMR switch and leave everything else unticked.
?All other settings like BrandmeisterMaster and Brandmeister security can be touched upon later.
as with DMR+ etc.

Re: Decoder for CW practice?
I did give Fldigi a quick try as I've used it with success before on Windows, but my initial attempts on the RPI failed to decode my keying although it was working okay with CW in all other respects.? I think the problem may be the way the audio paths are routed on the sBitx pi build?

Re: Decoder for CW practice?
One possible way would be to write a python script that reads a GPIO pin (or two, one for dots and one for dashes if you want an iambic paddle), plays a tone using the simpleaudio library. Then use jack to route that sound into a virtual sound card that FLdigi can use.?
?
I did something similar to this using a RP2040W to generate MIDI data that connected wirelessly over Bluetooth to a virtual instrument on my Mac, but it was mostly just to see if I could write it. I didn't go much beyond any practical application.?

I may misunderstand what you want but I think Fldigi would work.
I decodes CW and other digital modes just fine.
Like I said I may not know just what you are looking for Fldigi
