Did you run the proper install program in the drivers subdirectory?

?Thanks Jack, I think there could be a possible cause for my problem. When I connect the Nano to an USB port, it shows up as COM5. So I just used COM5 in the Arduino ide. Is there anything else I have to do?

Got my old programer connected to the Nano, but get no Com port shown up. Have to use AVRDude, but hate to mess around with commandline paramaters. Have to look if I can find some GUI for it. Would prefere to just use the arduino ide though.

Yes, the inductor is for L4 in the analog VFO if you decide to do without the Raduino for a VFO, must be out if you do use the Raduino.

No, the cap is for use across the tuning pot to avoid a bit of chatter there.?

• Solder the 0.1uF disc ceramic (marked as 104) between the yellow and violet wires on the tuning pot

Com port is correct set.

Programer now set to USBasp

I have another option for upload available as I still have a USBasp programmer as leftover from my times where I programmed flightcontorllers and ESCs for my multicopters.

That programmer has also a 6pin connector that fits to the 6 pins on the oposite side of the USB adapter on the nano.

I just removed the plastic around the pins to get them free, but they are cut and I think they are a bit to short now. Will try to get them a bit longer by heating up the solder and pulling them out a bit. Maybe I can get that connected via this programmer.

It is something like that:

Ups, sorry for beeing that stupid. I meassured just the voltage that was on A7 with having the pot at a random position. Of course it is changing. It goes from 0 when fully to counterclockwise up to 5.08 when fully clockwise.

The regulator gets slightly warm, but not realy hot.

When I now turn it on, the first line of the LCD shows 16 black blocks and the second line is empty. On the nano a green and a red led are lit, but I cannot see which one, because it is covered by the LCD.

I tried to upload a sketch, without having anything else connected to the nano. I think that should work?

Just to be sure, what settings do I have to use within the Arduino software?

I have the following settings:

board = Arduino Nano

processor = artmega328

programmer = AVRISPmkll

I am not sure about the progammer setting, but tried every single one and nothing worked.

Or should I try to upload when everything is connected and under power?

Hi

I added the wire color code to the connectors along with a segement?from the code that shows some of the uses for the 'unused' wires.

Has anyone tried out these 'unused' operations yet? There is a lot lurking in the code.

Hope this helps.

Randy, K7AGE

Does that 3.3v change smoothly when you rotate the tuning pot? ?Stay in the middle 1/3'rd of the tuning range if you try this, as you may not want to short that to ground or +5v. ?Is the regulator getting hot?

If either is true, I suggest you cut the wire from A7 to the pot, then try again reflashing the Nano.

Sorry, Mike. Guess I should have paid closer attention to the question.?

I'm just tackling mine. My radiuno came with a pre-wound inductor. I can't seem?

to find any reference as to where it goes. Any ideas on that?

Mark ?KC1GNH

The only other case I'm aware of where a Raduino died during calibration is that referenced in posts 20959 and 20906. ?John Smith says he may have had one of the spare wires short to the heatsink (which I assume is 12v), and blow something, which is very welcome information as we try to figure this out. ?But I don't think that was it, as it was his A7 Nano pin that blew, and that would have been firmly attached to the tuning pot. ?So we really don't know why that failed yet. ?Most likely that A7 pin would need to short to 12v to get damaged like that, though it's possible that shorting to the neighboring 5v tab of the pot could do it. ?Any further hints from Helmut or John of what might have happened would be most appreciated. ?

Elsewhere in history here these last couple weeks, somebody mentioned that having to reflash an Arduino in other environments is not unusual. ?That should not be the case, and if that's happening with the Raduino we need to track it down. ?For starters, never hot plug those wires, power everything down when moving wires around and double check your work before powering up, put tape over the ends of any flying leads. ?Keep wires reasonably short. ?Somebody with a scope should look hard at the 5v supply rail around that Raduino at power-up and power-down especially, perhaps we need another cap out there to avoid some ringing. ?Perhaps shorting 5v to ground and then letting it go is causing overshoot.

Here's my notes regarding what Ashhar Farhan's sketch is doing with the pins:

#define ANALOG_KEYER (A1)
#define CAL_BUTTON (A2)
#define FBUTTON (A3)
#define PTT   (A6)
#define ANALOG_TUNING (A7)

#define TX_RX (7)
#define CW_TONE (6)
#define CW_KEY (5)
#define TX_LPF_SEL (4)

The current wire-up is only using the CAL_BUTTON and ANALOG_TUNING from that set of 9 pins.
All but TX_LPF_SEL have code that reference them in the sketch, so should be considered used.

Here's the pins for the 16x2 display:
  LiquidCrystal lcd(8,9,10,11,12,13);
I assume the SCL and SDA pins are set up down in Jason's Si5351 library.

I had recommended John Smith use A6 as his replacement ANALOG_TUNING pin based on this comment:
 * A6 is to implement a keyer, it is reserved and not yet implemented
but actual code shows a conflict with PTT.  He might want to move PTT to A0 if there's trouble.
