Re: NTP-Server - location of STL case files

 

¿ªÔÆÌåÓý

Hello Bill

A bit more information about the W8TEE version of the MCT.? Jack (W8TEE) has a groups.io forum called SoftwareControlledHamRadio and located at:
/g/SoftwareControlledHamRadio
To join send a message to:
 [email protected]

Once you have joined you can check the file section and search for MCT:
/g/SoftwareControlledHamRadio/filessearch?p=updated%2C%2C%2C20%2C2%2C20%2C0&q=mct

As I recall,? Jack made the MCT open source and the one Hackaday page ( ) I saw when looking for "w8tee morse code tutor" said that W8BH had seen Jack's presentation that Jack did.? I also seem to recall that Jack had the project in his Microcontroller book that ARRL sold at least for a while.

Good luck.

Is this what you are looking for?? It worked fine for mine.



If for some reason you can not find/get it I have the files and
could send them to you.

Bill the Thingiverse description for that box says it is for the W8TEE version of the morse tutor.

Good luck.

Hi Erik,

Thank you for your message. It looks very interesting and I will try it.

Re: Show my own coding speed on Morse Code Tutor

 

Hi Vincero,

Nice work!? Someone told me they liked the Morserino's wpm display, so I tried their code, it seems to work reasonably well too, even for shorter words.

It calculates a moving average dit length and dah length instraightKeyInput()

in the dah-path
? ? ? ? ? avgDahTime = (3* avgDitTime + avgDahTime + timeDown) / 3;
in the dit-path
? ? ? ? ? avgDitTime = (4 * avgDitTime + timeDown) / 5;? ? ?

And then in the CheckSpeedLive it calculates wpm
? wpm = (wpm + (int) (7200 / (avgDahTime + 3*avgDitTime))) / 2;? ? ?//// recalculate speed in wpm

Sorry for the delayed response, but perhaps you'd find this an interesting alternative.

Re: SD Reader Difficulty (MorseTutor, ESP32 version)

 

Thanks George. ?I believe I have files named correctly. ?Beginning to wonder if the card reader is malfunctioning.
Re: SD Reader Difficulty (MorseTutor, ESP32 version)

 

I just checked my SD card. It works fine. So, the question I have first is the file name.

I Insert the card first, then turn on the Tutor.

Make sure the file names are old school 8.3 filenames. I use a something like testtext.txt; in fact, all the files I have are *.txt.

Ask Dann, he is a great fount of information.

SD Reader Difficulty (MorseTutor, ESP32 version)

 

Brand new to the group and have a question after searching previous posts.
I have successfully (I think) assembled Bruce's MorseTutor?(ESP32 version) after receiving the parts kit from Vince and Dan.
Everything works great except the SD card option.? I have loaded files onto a couple of different SD cards, and they appear in the file section list (first character dropped in each, however).? I am able to move down the file list as I rotate the encoder.? Upon depressing the rotary encoder to select a file, the program just opts back to the Receive Menu.? Have examined the script and double checked that the libraries are installed in the Arduino IDE.? Everything compiles and uploads without errors. Have checked all pins and solder joints.? Anyone run into this problem? Any suggestion appreciated. Thanks.

The one line change in?char?straightKeyInput()?should be done also in?char paddleInput()

Re: Show my own coding speed on Morse Code Tutor

 
Edited

Hi Bruce,

I think I have found a good preliminary solution. Please could you have a look?

I did not make a diff but just copying here the 2 functions I changed and the new one that I wrote.

A further optimization is probably to remove the management of the character sent from?void?checkSpeedLive(char?c) because it is not necessary.

Hi Bruce,

Thank you!

I will start investigating from there. I will keep the you updated on my findings and tests.

Re: Show my own coding speed on Morse Code Tutor

 

Hi Vincenzo.

Writing code to determine the speed of your fist is... not easy.? ??

If you want to experiment, I suggest looking at the routine called 'checkSpeed'.? ?This routine sends the standard word 'PARIS', then computes the WPM speed based on the number of elements and the elapsed time.? ?Try writing something similar that counts the elements being sent and the time spent sending them.?

Let us know how it goes!

Morse Tutor ESP version

 

I had some boards made and assembled without issues.

I am having a hard time understanding on how to program the ESP32 module with Arduino ( I am a real rookie). Seems like I am missing some libraries.
Re: ntp_server.ino Sketch

 

Great job, Ross.? ?I am glad to hear it is working.

Yes, Pin 3 is the time pulse signal (1PPS).? See page 12 of?

I will upload the final sketch soon and post it here.

Hi Bruce

I have gone through the whole tutorial (even the interrupt tutorial) and everything is working as advertised.? The only problem I encountered was with my gps module - a GY-GPS6MV2 - which doesn't have a pps output pin.? I soldered a connection to the led resistor which is connected to pin 3 of the NEO-6M-0-001 chip which I assume is the pps signal output.? Perhaps you can confirm this.? Anyways, all is very satisfactory and I am amazed at how far away I can receive a wifi signal from the 8266 module with no external antenna attached!? ??

Thank you for the fun project and learning experience? -? Ross
