Re: [BITxV6] BRICKED recovery help needed
?I'll agree that having a spare Nano is a good idea. I bought 2 or 3 myself, pins not soldered that way I can experiment with the raduinos for other project ideas, I have a coupe of Unit's, and another bigger arduino that I bought to experiment with. ?BTW, I don't care for the green screen that come with the raduinos, so I changed one to a blue screen. Pin for pin compatible, just had to solder ?Pins to the blue, and popped it in, so nice. ?Anyway, always a god idea to have spares when you experiment.

Having spare Nano's, you can practice downloading firmware without even touching the uBitx.
Once it is downloaded, can power everything off and with proper anti-static precautions,
move the new Nano into the socket on the Raduino to try the firmware out.
If the uBitx doesn't work, you can go back to the original Nano, see if that fixes it.
Having spare Nano's also means you can play with them on other projects.
They are very useful and fun.? You might get a few of the cheap 16x2 displays also.
Many have noticed that the uBitx receiver works with the uBitx power switch off
when a USB connection from a host computer to the Raduino is made.?
The power from the USB connection goes "backwards"
through the LM7805 regulator up into the main 12v rail of the uBitx.
Though that 12v rail only has something less than 5v on it, the receiver
behaves more or less normally.? It is possible that this could blow some 5v connection
on a Nano due to too heavy a current, though I'm not sure anybody has experienced this.
Might be best to add a 1n400x diode between the main uBItx 12v rail and the LM7805
regulator on the Raduino to prevent the backward flow of current from the USB connection.?
I don't know why your uBitx failed.
At $3, the Nano clones are of variable quality, perhaps it simply died for no particular reason.
With any luck, replacing the $3 Nano (after first burning appropriate firmware) will fix your uBitx.

Something like this isn't great for teaching students in a course especially when cost is as high as it is.

Phillip, We have discovered that the Indian customs have opened quite a few of our boxes and packed them back badly. HF Signals is committed to replacing all of them. Write to hfsignals@... with pictures. - f
Mine turned up with damage. The volume pot broken off the the board, marks on the touch screen, and damage to the corners of the case. Also chipped paint work.

Mark, Just before you ship it to someone else.. the rig is eniterly usable without the touch too. Here is how : Tap the tuning knob and a white square showing the focus will appear around one of the buttons or frequencies. Use the tuning knob to move it to the other button. Press again to select. If you press it over an already selected frequency, it falls into fast tuning mode, press again for normal tuning. I didn't get around to doing the same with the setup menu but it is used just a few times in the life of the rig. - f

Re: ubitx #v6 Screen Speed Mod

I¡¯m on vacation right now, but when I get back, I¡¯d be happy to share a branch I made to support interrupt driven encoder wheel. Rather than calling read_enc() and waiting around 200ms or whatever it waits, instead the pin change interrupts on the encoder wheel call an ISR to increment or decrement a counter, and read_enc() just returns and clears that counter. So the UI responsiveness is Improved (immediate return instead of waiting to count clicks) and it doesn¡¯t miss clicks when not looking for them.?
I got this working, then immediately left for vacation with the family. If you¡¯re interested, I can share a PR this coming Saturday or Sunday.?

?@Joel - okay, great. Sounds like the PDQ branch is reasonably stable, then. That's what I like to hear :) @Andy - are you having issues with the pdq_gfx_update branch () that this thread is discussing, or are you still on the stock software that shipped with the radio? If you're asking for general setup help, this thread probably isn't the best spot to ask. However, since you did ask here, I'll give a quick answer summarizing :
- Turn on radio
- Tune to a frequency you know there's signal on, e.g. a local AM station, or 10MHz for WWV. Tune to what the known frequency is, not where you actually get the signal while tuning.
- Press and hold the tuning dial in until you enter the setup menu
- Rotate the tuning dial until "Set Freq..." is selected
- Press and release the tuning dial to enter the setting
- Rotate the tuning dial until you get zero beat
- Press and release the tuning dial to save the setting
- Rotate to the "Exit" to leave the setup menu
Once you've done the above tuning, you can then change the BFO to get things to sound "right". Reed

Will do. I will give it a good testing tomorrow.

Hi Reed.
Just managed? to compile your firmware and install it.
Great that's one hell of a lot faster. Very happy, thanks

@Philip - I'll try and get you a hex file tonight. I don't have one on hand.
@Armando - pdq_gfx_update is what I'd recommend, since several people have reported success using it. one_stop_settings apparently has some gremlins in it that I won't be able to sort out until I actually finish my build, and fix_morse only fixes the "F" in the morse playback without modifying the screen at all.
Reed

Reed, which branch are you recommending as most stable and fast? pdq_gfx , one_stop or fix_morse? A
Philip,
Did you update to the pdq_gfx_update branch, or something else?
Reed

I cannot work out how to compile it. That is why I was asking for compiled HEX file.
Philip

@MadRadioModder,
I mean, sure, if you buy a faster processor you'll get better performance. That's not really the point, though. My branch gets reasonable screen refresh speeds at zero additional cost and with zero hardware mods.

Yeah upgrade to a Teensy 4.0 with W0EB¡¯s daughter board and watch how fast it goes¡? The display will be the rate limiting step. ? ?
