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

In theory the action could be done as well as a button in say menu option?
Perhaps something like this?

Now, if someone clever could incorporate the 6 second hold-down of the encoder switch to initiate a proper shutdown as described here...

Power zero on 10m / Drive number
So, I'd been watching another thread for resolution, but it may not be the same thing.
Questions up front.
1. Any reason why 10m is 0W??
2. See my drive? it's 96, and I don't know why I can't get it to 100. When using the wheel, it won't go any higher, though it certainly goes lower.?
These lead me to believe both are software configuration related.?
?
The problem:
I initially had the issue with FT8 locking up the zBitx. Updating the both the Zero and Pico software resolved that.
I'm at 1.6 and 3.051 now.
Running sBitx on the external monitor resulted in 0W out.?
?
However, I'd still get 0 watts out when transmitting FT8 on 10m.
?
However, I remembered I get less output on my sBitx at 10m, so I setup a 20m vertical and I got power out. I haven't had time to check 12/15/17m. Could there be a problem with the calibration files that I absolutely did not backup when I did the update?
?
Any guidance would be appreciated!

I would agree with Ken.? However, we are assessing the impact of this on HF Signals (which is a Delaware company that files its taxes in the USA) the impact should be minimal. We will wait and watch.If any of the buyers face additional tariffs, write to us at sales@... so we can see how we can do an impact analysis. - f?

Re: Zbitx power cord connector
My plug failed on like the third start. I ordered this and they transmit power fine (one to replace the failed plug and one for the power supply), but they’re slightly longer. A very small o-ring would take up the space if that’s a concern.?

I would have to agree with you on this point.

Ron, I would like you to review the code: 1.? Here, we setup the ISR (interrupt service routine) to call a function called key_isr whenever the state of the paddle chages (press, release). 2. The key_isr () reads the status of the the two paddles (DASH and PTT) and stores them in global variables ptt_state and dash_state. 3. the cw sending loop has to generate 96,000 samples a second. And it cannot spend?time reading the gpio pins to see if the any new symbol (dot/dash/space) has been generated by the user. Instead, it just reads these two variables. This is done by the routine key_poll(). .4 Read key_poll (). You will note that it executes very quickly. To know what type of key we are using, it doesn't even to a string compare of the CW_INPUT settings, instead it just samples the 6th letter with is different for all the three cases (Straight, Iambic and Iambic-B). Let me know what you think of the?implementation and if it can be improved. - f

A priority interrupt handler would need to be written with good real-time coding practices (bounded time algorithm, no locks, no API calls that could involve memory management, etc.). ? But this should be possible.? Then post the key inputs with time stamps to be handled by the priority keying sidetone process, which perhaps will run only a few milliseconds later.? The time stamps on the interrupt data would prevent the dash from being handled before any dot, if that was the key closure sequence, and solve at least one issue with fast iambic keying that polling with a slow CPU on a loaded system might never be able to completely solve.

Agree.? With you being a Linux user.?? I think Farhan mentioned he wanted to avoid giving elevated access to do the shutdown. When at home I ssh into it to issue the shutdown -h now command?
