Re: CW on zbitx

 

I updated my Zbitx yesterday (Wednesday) to 3.051 and 1.06. Yes it fixed a couple issues but CW remained unusable. So today (Thursday) I decided to update again, thinking I might have gotten an earlier Raspberry pi copy.
Now I have bricked the radio... No boot up of the Pi ( screen is ok). With an external monitor the Pi doesn't go past the first steps of booting, freezes and ignores keyboard and mouse.

It stops at the following:
?????????? USER???????? PID ACCESS COMMAND

?Line 4527: ?modem poll is only being called every 20th tick

Modem_poll , then calls cw_poll -but this cannot happen any faster than every 20th tick with the current code

It is actually CW_POLL that really causes transmit to occur. But this cannot start any faster than every 20th tick because of the way the routines ?are being called.

It is easy enough to prove us wrong. Simply change the calls to modem pole to occur every fourth tick (instead of every 20th tick ) and if it doesn’t get a lot better than we’re wrong.

Wishing you the best!

Re: #zbitx I would really like a formal way to shut down the software gracefully #zbitx

 

I do not yet have my zBitx setup, so I can not test using a macro to call JJ's shutdown script in the toolbox.? The macro button, like the logging function buttons, could be available on all screens.

Geeze.. so sry I am slow to really look at the pics.. I don't really see frame damage..?
And I see the ref output on the rear panel.. guess this model didn't have the front connector for ref?
IF the reference works on the rear connector, would you take $275?

thanks for your patience.

Re: CW on zbitx

 

I am not making myself clear. The cw_poll nor modem_poll has any use of reading the keyer.
I hope it is clear. None of the polling routines are used expect to start the transmission.
The keyer is sensed by the isr routine that updates the global variables with the current state of the paddles.
It is the key_poll that reads and returns the state of the paddle 96,000 times a second.
I repeat, nothing to do with either the ui_tick nor modem_poll nor cw_poll.
It would be best if everyone read the detailed email I posted with reference to the exact line numbers of the code. We can then discuss the code.

Re: Waiting for the zBitx to start…

Until someone can help you...
I’m no expert. If I was in your situation, I would probably get another SD card. Download the image, burn a new SD card and put that into the radio to give it a try.?

You would still have the original SD card available if needed..

Re: Does zBitx have SWR display?

 

Hi Paul,
?
I ran into the same issue. v3.051 is currently the latest version. In my case, the git branch was set to "farhandev" instead of "main". This also seems to be the difference between the ./update and ./update_zbitx script - the former does not explicitly set a branch, while the latter sets the branch to "farhandev" after running the git pull. In the ~/sbitx folder, I had to manually run "git checkout main", then ran the ./update script. This brought me to v3.051 and now I get proper readings both via HDMI and on the "head unit" (previously, the "head unit" kept displaying the voltage/S-meter and power/SWR remained at 0/1.0 via HDMI despite appropriate power output).

Re: CW on zbitx

 

Calling anywhere from 5 to 10 times more frequently would probably result in significant improvement. In the sBitx software, he increased it to 20 times more frequently and it was amazing.
