Andy -- good work and well written.? One thought: the discussion of Arduino IDE might be best moved back from the lead.? Most Noobies need the context of all this, and the IDE / code discussion could be placed in a section following some overview and context.

But great!? Well done.

Hi Reed,

Loaded today's commit, a quantup leap in screen response time.

Observations -
TFT USB/LSB buttons do not change CLK1 consistently.
CAT from HRD changes CLK1?but TFT USB/LSB indicators do not change
Tuning below 1mHz tunes Si5351 correctly but gives 9999.50 display indication.
Tuning encoder smoothly changes CLK frequency but TFT display lags.
Might it be possible at some stage to add a decimal point (or a small space) between the displayed mHz digit and 100s of kHz?

Thank you, great work,

73 Bob GM4CID

This is what I use on a uBITx v5. Not powered Maxxter. Holding the usb soundcard connected directly to uBITx Mic and Speaker ports. Then usb cable to uBITx Raduino. At left RTL-SDR dongle connected to SDR signal at IF of the uBITx and into the laptop via usb.

OK, that figures.....? I'd thought that the AGC out pad was going to be strong enough, given it's level being much better than the vol. pot "Hi" level. Given a range of incoming signals, I'm getting? .090v to 1.1v DC out from the AGC s-meter solder pad.? No prob, I'll add the amp to the vol. Hi as directed.?

Jim, the resistors read open or infinite resistance.?

The radio has never transmitted. No other HAMs in my neighborhood that I know of.

Good news gang,? I've found an easy way to keep from having to make ANY hardware mods to the Factory V6 Raduino.? When I mentioned that you have to protect the Teensy 4 from the +5V on the A6 input pin by removing R2 (the keyer pullup resistor) and cutting the line from A6 to the KEYER pin on the right angle plug to the main board, I'm sure that turned many of you off, not wanting to modify your Factory Raduino by cutting traces.

I am kicking myself now as I forgot there are more I/O pins available on the Teensy then ever were on a NANO.? We have not implemented all of these, but it so happens that there are 2 of those extra inputs that ARE brought out to pads on the adapter board, the A8 and A9 inputs.?

The simple solution is, when building our adapter, simply leave out (or cut off) the pin that plugs into the A6 input on the Raduino's NANO socket.? This eliminates any possibility of the Keyer line causing any problems.? Since the keyer does not work reliably with 3.3V applied to the Teensy's A6 input and a different Keyer routine had to be used with a separate Paddle Jack, there is no reason that the extra paddle jack can't be connected to the A8 for dot and A9 for dash (or the other way around) paddle connections with a separate 3.5mm stereo jack used for paddle input.? The hand key stays on the PTT A3 input where it is in the first place, no changes needed there.?

It's an extremely simple software change in our software to use those inputs rather than A6 and A7.? That way A7 can remain a spare as it is on the factory Raduino and NO repeat NO hardware mods are needed to the V6 Raduino.? I'll post a revised construction manual for the Adapter kit later this morning and all future kits will be supplied with a 3 pin, right angle header to go in the extra pads.? Right angle is needed to keep it from interfering with the Teensy's USB connector which is used for programming and CAT control.

First of all let me wish all members of this wonderful group a happy new year 2020.
We have some remaining enclosures for Sale which are bitx40 and ubitx for version 3,4,5.
There are some standard case case with 1602 display and Nextion Display cases in all sizes for different Nextion Displays. Also individual faceplate for 2.4 inch and 2.8 inch display for standard case are available .
We may not be manufacturing the enclosures so if your kit is without a case it would be good idea to go for one.
We are working on our New Kit for Bitx which will be announced very soon.
My sincere thanks to all friends world wide who have provided us with a great importunity by purchasing our enclosures
and other kits.

Not too many, but maybe per product (BITx/uBITx/versions ?) and divided if needed for hardware and software

Aaargh.?

Update! I believe I figured out a fix to the white screen at not issue, committed to my pdq_gfx_update branch, f1ea1fd081d128895f336d0ca16de6246a422f2f.

The reason for not coming up appears to have nothing to do with power and everything to do with the initialization sequence in the drivers. It seems that my screen starts up in deep sleep mode sometimes, so by sending the right sequence to wake it up before initializing the driver, everything works as desired, no matter how many times I power cycle.

Thanks to everybody who chimed in here. I really appreciate you taking the time to help a stranger like me :)


Reed

Hey Andy,

I hope you got a good night's rest. I think I have a fix! The attached hex file for me has NOT white screened EVER in my testing. Prior to this commit (f1ea1fd081d128895f336d0ca16de6246a422f2f) I'd get a successful screen render once every blue moon. Now, I have yet to get a failed screen boot. Hopefully it solves the problem on your end too.


Reed

Added commit f1ea1fd081d128895f336d0ca16de6246a422f2f to this branch, which fixes the white screen startup issue for me.

OK Reed Thanks it is getting late here now I will give it a look tomorrow.
