Steve, I probably would have whittled the usb plug-housing.

I checked all my USB leads and none were small enough to plug into the Morserino.
The smallest I have is shown below and still wouldn't fit. So I needed to file the acrylic cover (and caused two cracks by the wire antenna :-(  )

But no-one else had this issue?

Try loosening the screws and reposition the PCB closer to the edge of the plex. If that fails enlarge or slot the holes in the plex with a round file – tweak it to work.

Cheers,

Bill

No issue here but it did make me curious, so I rummaged around in my wire drawer to find the largest micro USB cable I have.
This is the largest USB connector I could find, and when fully seated it still comes up shy of the outside edge of the acrylic.

Hello,

I gave a look at the code and found the statement that can print all characters on the Serial port (it is inside the printToScroll function - row 3854 ).
For what I need it is enough for a host application development but it would be nice you could add a menu option that can enables the feature whichever one want.
I hope you'll agree.
Anyway thank you very much for this great project.

Best regards

Enzo, iw7dmh

P.S.: I modified he statement in
        Serial.printf("%s", text.c_str());


Re: battery questions

Willi, OE1WKL
 

The Heltec module has a charging circuit on board for LiPos. So they will be charged up slowly, and charging is switched of when the battery is full (no overcharging). They do not provide low voltage protection, unfortunately. So you need to take care to switch the battery off when not using the Morserino for a longer period…

I've read several of the battery threads, I'm not asking where to get one.

My questions are:
How long would the Tattu 600mA battery last roughly?
I assume LiPo batteries are like my LiFePo4 batteries in that discharging them below a certain voltage is destructive to the battery. Does the Morserino32 look out for this?
Does the charging circuit 'switch off' when it detects the battery is charged?
And then I assume it switches in and out to keep battery topped up?

I'll probably use it at home via USB power anyway, but battery would be good for other situations.

thanks
Steve

Also many, if not most, of the small lipos have protective circuits built in.

Re: Speaker

Bill Cusick
 

Hi,  you should have a positive voltage on one pin, and 0 at the other. I have zero voltage for both pins.  I will be using the headphones only, I'm okay with no speaker, but if your willing to sell one I would buy the speaker. If you need the speaker for a kit then please keep the speaker for a kit. I most likely overheated the speaker pins when soldering so it would be fault.

Txs for your help
Bill

Bill,

While it cannot be ruled out that the speaker is defect, it is rather unlikely (in such a case you can get a replacement speaker from me - I am afraid they are not available anywhere else anymore, as I bought up all of them that were left on the market).

As a first step, can you measure the average voltage on each speaker pin against ground (use the pad where the black wire from the battery connects as ground) when the keyed is producing a series of dashes… you should have a positive voltage on one pin, and 0 at the other.

If that was ok, unpowered the Morserino, and with the help of a small battery (1.5 V, do not use a LiPo) see if the speaker makes a sound when you apply the small voltage quickly to the speaker pins.

If no noise can be heard, the speaker is indeed at fault.

Re: audio from speaker

Willi, OE1WKL
 

You should not get an "audio screen" - that's part of adjusting the level of the input  signal on connector 2, not the speaker volume (and you adjust that with the blue trimmer).
To adjust the speaker volume, click the red button QUICKLY (!) - the volume bar on the top right of the screen will be inverted, and you can adjust the volume with the encoder.
