Problems with Arduino Nano: has anyone the program for BiTX 40?

 

开云体育

I to all, I'm Valerio, iu5hkj.
For a mistake, I've connected one of the orange wire that came from the Arduino Nano to the power supply, so Arduino dont't never works.
Can you help me?
I need the program in Arduino Nano, so I can substitute it (Arduino with a new one), in this way my BITX 40 can works again because it works really well, is a greate trasceiver and its very useful for portable use.

Thanks from iu5hkj Valerio

 

There are two orange wires in the supplied wiring harnesses that connect to the Raduino.
One of the orange wires goes to pin 15 of the connector labeled "OSCILLATORS" in the schematic,
this wire should be connected to +12v as shown in the wireup diagram.
The other orange wire goes to pin 5 of the connector labeled "CONTROLS" in the schematic,
this wire goes directly into the A3 pin of the Mega328p on the Arduino Nano processor.
The schematic is here: ?http://www.hfsigs.com/bitx40v3_circuit.html
The wireup instructions are here: ?http://www.hfsigs.com/bitx40v3_wireup.html

Sometimes shorting a Mega328p pin to 12v (such as the A3 pin) only blows the IO cell for that pin,
but since nothing works at all anymore it seems you have blown the processor and it must be replaced.
You might try buying a new Arduino Nano processor board off the web (perhaps $4 USD),
but installing that on the Raduino board will require removing the 30 soldered pins of the blown Nano first.
You might buy a new Arduino Nano plus one of the Si5351 breakout boards and a 2x16 display, create your own Raduino.
Neither of these will be trivial to do if you are not experienced with this sort of thing.

Perhaps I am wrong and someone will have a suggestion for an easy fix.
But I think your easiest solution is to buy a new Raduino from HFSigs.

It is possible that the mistake only zapped the program inside the Nano
without destroying the Nano.
I would first try programming the Nano using the instructions found here:
? ??/g/BITX20/message/31491

I do recommend you download Allard's code as mentioned above.
It should work just fine without any hardware mods to the radio,
and fixes a number of issues that were in the original code shipped with the radio.
If curious, here is that original code that shipped with the radio: ?
It requires the use of an old etherkit Si5351 library, not compatible with the current library.

For what it's worth..I have down loaded my DDS pictures with the Nano removed.? I installed headers so I can Plug n' Play nano's as improvements come in.? Just remember the USB connection on the NANO points off the DDS as always (after you solder in the headers).
Hope this helps along with the other BITX Group help/ suggestions.
The extended LCD display is something I'm trying out.
You should be able to zoom these pictures

"but since nothing works at all anymore it seems you have blown the processor and it must be replaced."

That's a pretty good idea, Jerry. I have done that with the TQFN package. The only problem is that if
the processor is blown, most likely the CH340P chip is blown also. In fact, the CH340P seems to be
more sensitive than the mcu. One has to replace that to get USB communication. However, the mcu
can be programmed with ICSP (if the traces are good).

Try re-programing at first, but If your Nano is wasted, get another; it is more effective in the long run
(and they are cheap enough to buy 5 at a time).

Excellent, Larry.
If one gets a new Nano, install it with male and female removable headers.
It makes things a whole lot easier, and does not effect operation to any great extent.

The headers are easily available (up to40 pins) online.

Most Nanos come with the pins installed or you need to solder the pins into the Nano

Nano has 30 pins per side and sometimes the six pin header pin is included.

?

Use the below to search for like items or order from these sites as shown.

?

New Nanos usually come with the Nano port - USB cable so you can down load sketches.

?

I program my Nanos not plugged into the DDS.?

Just make sure the NANO (pins) is resting on non-conductive surface.

?

I’m sure other members have better parts sources IE ? ?K9AGE

?

I would use pre-cut 15 pin headers as I find they are a bit tricky to saw…I use a FINE tooth hobby saw.

?

The pins are segmented so small wire cutter pliers should work.

Make an effort to keep pins and headers at right angles to the Nano./ DDS PCB.

You can solder a center pin and or header and check for alignment. Then good to go-solder all. Check for solder bridges etc..

?

If you’re not sure about this procedure- note the component side and place a mark denoting the USB port for Nano insertion.

?

And finally I write the version # on a self-stick Dot? This way I know what sketch I downloaded into the Nano .? I have about 4 Nanos floating around on my desk so I try to keep from confusing myself.? Otherwise just boot the Nano and DDS will tell all.

I show and used more wires on the LCD than are needed,.,to ?lazy to make more efficient for now.

I encourage you to shop around and I like free shipping :)

I’m almost certain many BITX’ers know of better sources.

Can you point me to a source of the headers and ribbon cable you used?

I am very new to all this. I would like to try your approach for easier modularity?

Thanks
