Re: #ubitx new Alternate software for the uBITX #ubitx

 

Raj,
In the documentation for "wiring up" on the HF Signals page the A7 (violet wire) is listed as a SPARE and the original code doesn't read the paddles properly. It was/is very difficult to send proper CW with the original. I figured that in a $120 radio I did not need an S meter or a power meter so until digital lines can be freed up to allow for other uses for both A6 and A7 our code, as written will be made available for those who chose to use it. It's too bad the designer of the Raduino card didn't use a "level shifter" on the I2C bus to feed the Si5351A as then I2C could have been used to drive the Display, freeing up 6 digital I/O lines and the keyer could have been properly implemented in the first place.

Not arguing with you Raj, just telling why we used the "SPARE" A7 line - Farhan jee said in the documentation it was a spare and we should coil it out of the way OR find a use for it. We found a use for it.

The uBitx A7 was left for S-Meter and Power meter inputs. That is why the original sketch uses one input to sense
3 different states - straight key, Dit and Dah.

Hi gang,
Ron, W2CTX and I (W0EB) have been steadily working on fixing some of the CW problems with the uBITX software and also changing the tuning over from the accelerated tuning for band change, etc. We found that this method, while liked by some was difficult for some of us to tune to the frequency we wanted so we set it up with a cursor under the digit to be tuned using the encoder button to step the cursor position. We also used the spare (A7) line as the dash input for the keyer (you have to add another 4.7K pullup resistor, this time to the A7 input). The zipfile complete with all files for compiling and uploading to the uBITX with the Arduino IDE (version 1.8.5 or later on the IDE). If you have your IDE set up right, it should compile without errors and upload to the uBITX just fine.

The CW Keyer module uses code that came from the open source Ten-Tec Patriot and Rebel code and the timing has been corrected so that the paddles work properly and all the available speeds from real slooooow to 50 wpm. I've been using this code on the air for over a week without a problem.

We also re-ordered the menu(s) and added a few items that are all explained in the manual included in the zip file.

Ron and I sincerely hope this program version will allow you to work CW much better and it addresses some of the requests for features that are different from what was supplied in the initial version that came loaded in the factory uBITX.

Jim Sheldon, W0EB for Ron, W2CTX and myself
