zbitx schematics and source code

 

The zbitx source code is now available on github.?
and?

Please note that this code has not been tested on the sbitx, though it has been derived from the sbitx base.
A few things to note:
1. The 64 bit OS didn't have any significant advantage and using its PulseAudio was adding to the auto start required for the zbitx. Hence, this has been tested to compile on 32 bit Raspberry OS.
2. This works with as well as without the front panel.
3. The schematics are also included.
This is the version that will start shipping in the next 36 hours. We are finally loadng it up!

Farhan,

Thanks! I appreciate you and your team's hard work in this and look forward to the arrival of the zBitx soon.

Hello Farhan,

?

Thank you for sharing the details of the zBITX project with us.

?

The zBITX Front Panel Schematic seems to be missing.

?

Could you share that too ?

?

regards

Charudatt

Congratulations!? Perhaps this explains the sudden increase in wspr traffic from Indian farm land...
 

Sorry for snooping into the code but
?
? ?else if ((encoder_now == 0 && encoder_now == 2)?? This line should compare encoder state to encoder now
? ? ? || (encoder_state == 2 && encoder_now == 3)
 

Farhan,
?
Thank you, for all your hark work. It’s been well worth the wait!!.
?
Tanks again,
Robert, AG6LK?
 

Farhan,

Sort, should be “Hard Work”.

It's open source. Snooping is encouraged!

I did a side-by-side comparison of this zbitx repo and the farhandev branch of sbitx. ?They look suspiciously similar, with some newer changes brought in, but it looks like it’s still clearly meant for sbitx. ?All the strings still say sbitx. ?So this is not really what you are shipping, is it? ?If we look at git log:

there is only one recent patch, addition of the schematics. ?(Thanks for that!)

The more similar it is, the easier it is to keep working on patches for both zbitx and sbitx at the same time. ?But I would think you would factor out the things that are different into as few files as possible, if they continue to be that similar. ?

I am working on some patches, trying to separate the frontend from the backend so that other UIs are possible. ?So I wanted to see whether I can easily apply them to both code bases. ?But it’s hard to believe that you are going to routinely run a version with?sbitx_gtk.c as-is, considering that your display is now an Arduino project connected over a slow channel, not an X server, and can’t show the GTK-based UI. ?Of course that UI is still useful if an HDMI monitor is attached, or for remote-X11 use over the network; but not so much on the zbitx as it ships? ?So my goal is to eventually have a radio daemon with no UI, and separate UI processes as needed. ?I think we both have the same problem: GTK is not useful if you don’t want to see that UI anywhere, and yet it’s hard to remove. ?I figured maybe you started to take some steps in that direction.
