This is just speculation, I haven't tried it myself having not yet delved into the programming to activate it:
Has anyone tried the guts of a PC-mouse as an encoder? I'm thinking a mouse with scroll-wheel (most have a mild 'detent' feel) - perhaps an old(er) ps/2 plug type? Use a ps/2 socket to retain the 'foolproof' pluggability. Disconnect the wiring (maybe leave supply + and -), and wire out the opto's of the wheel. One will be SDA, the other SCL. Perhaps also a/the button/s? one as encoder's 'push' menu/function for step-change etc (I'd use the right for that), the other (left being more intuitive for the more prevalent dexterous :) of the populace) for a convenient PTT... Note: will they pull up or down?
That's 6 wires (if the PS/2's connector pins are all wired through the cable - they might not for a mouse) - SDA, SCL, +5V, 0V, menu and PTT.
If your scrapped mouse is a 'track-ball' type, remove the ball to remove the temptation from the kids to swap it to their old 'junker' PC. Pop in a large nut from the garage/workshop's junk-heap to lend weight if required.
Feedback? Flames? Go to it ...

Re: W8TEE TFT/ VFO DISPLAY BOARD BOARD
Hi Mike ? Thanks for the tips My DDS has jumpers on J1 J2 and J3, and it¡¯s definitely an AD9850 with 3 rows of 7 pins. I have e-mailed the seller in China to see what can be done. I have limited test equipment, but I¡¯m taking it over the weekend to a fellow amateur who has a spectrum analyser to see what it is doing ? 73 de Charlie GI4FUE ?

Re: W8TEE TFT/ VFO DISPLAY BOARD
Thanks that's the picture i'd been looking for.
Together with the recommendation to use buffered output for the VFO this clarifies wireup a lot.
Thank you very much for the great work Jack

Sounds like a hosed nano. I'm assuming you have the CH340 driver installed in your computer?

Re: W8TEE TFT/ VFO DISPLAY BOARD
Jack ? Thanks. Question:? External power on picture states 7-9 volts. I have been using 12 volts. I assume my assumption is wrong and that a voltage regulator is needed to reduce 12v to 7-9 v for the external power input? ? ? Art

In the "wire up" section of HFsigs.com, under "alignment of the bitx40" it says to turn RV1 (PA bias) fully clockwise (off) and with an ammeter in the PA power lead (so you are measuring only the current to the PA, not the whole radio), adjust RV1 for 100 ma with PTT activated but no mic audio. After that, RV1 should not be touched. R136 which is usually about mid-point when you get your bitx40, is the only control that should be adjusted to get about 1A on the ammeter when you key the mic and talk loudly into it. This is when transmitting into a proper 50 ohm dummy load, as a poor SWR can mess up your measurements. For example, the wires to the antenna connector should be no longer than a couple of inches long, if a longer distance is needed use 50 ohm mini coax to avoid causing a poor SWR at this point.
Don't "daisy chain" grounds or power connections to different circuits. The 3 grounds and 3 power leads (from Raduino, main circuit board, and PA power) should all go to a common tie point near the DC entry point on your enclosure.
Don't allow wires to lay on top of or up against the underside of the circuit board. All wiring should be kept above, below, or to the the side of the circuit board about a half inch if possible.

Grab your voltmeters guys. Check the input and output voltages of the 3 term regulator hanging off the side.
Also try unplugging the connectors going in and plugging the Raduino in to your PC.

error found !!!!!
headphone connected to LM386 pin 5 and there is audio ...... looking in diagram it must be C111 there have to be changed

that's where I am right now... no display.

Re: W8TEE TFT/ VFO DISPLAY BOARD BOARD
My bad...and stupid. If you changed the symbolic constants up near line 121 and 122, then use the following at lines 1415-1418
? ? ? ? ? if (flag == -1) { ? ? ? ? ? ? ? ? ? // Too low ? ? ? ? ? ? currentFrequency = VFOLOWERFREQUENCYLIMIT; ? ? ?// Set to min ? ? ? ? ? } else { ? ? ? ? ? ? currentFrequency = VFOUPPERFREQUENCYLIMIT ?; ? ? ?// Set to max ? ? ? ? ? }
That's the first stupid thing I've done since lunch...

The default is 7030 if no?EEPROM recorded before.
You maybe check the librarys as described in the?TFTVFOManual.
For checking the display, you can compile and run "graphictest_kbv" in the MCUFRIEND_kbv Directory.

Good luck and success! (and maybe a quick delivery of a new DDS...)

If you have a scope, connect it to OUT2 on the board. You should see a sine wave.

Hi Jack ? I am using a KY040 connected to the correct pins¡I get the feeling I have an issue with the DDS because if I remove it, the code behaves in the same way without it. Unfortunately I do not have another to prove or disprove. ? 73 de Charlie GI4FUE ? ? Usually, failure is because the clock and data lines are not connected to the proper I/O lines on the controller.

I expect speaker is ok, have tested it with a 1,5V batt. and it gives a " blob"?
everything have worked until I made a complete rewiring and connected parts for CW !
I do not use connectors instead I have solder wires from Raduino to Bitx40 board
