Re: bitx v6 is here

Oh wow…thanks Farhan! That’s pretty useful information to have. I think that putting keypad control together will be useful still, especially for direct frequency entry, but glad to hear that all functions can still be activated without the touch screen. With morse output, it really could be used eyes-free. Great news, and I’ll pass it on.

All the user interface is usable without needing touch. If you tap on the tuning knob for a second, you can move the focus from one button to the next and then click in the button to select again. Each button has text associated with it that can be read out. I have taken care to see to it that all features are accessible with and without touch. For example, the ability to enter a new frequency using the touch pad is replicated in fast tune where if you hold down the button while on one of the vfos , you can now quickly move across the bands in 50 khz steps.

The function names are confusing as well..many variables are declared and not used any more. There is a large amount of code that is commented out as well. I have to clean that up, refactor reassemble. I will hopefully do this after Christmas.
The graphics library should really be called just a user interface library. The ILI9341 uses a SPI interface where it can fill a rectangle with a 16-bit colour. I used this to draw vertical lines, horizontal lines and pixels. No other graphical primitives have been used. The text characters are plotted pixel by pixel. The entire graphics routines are less than 100 lines. An often reused routine is the drawText routine that draws text centered inside a rectangle with a border. That makes all the buttons trivial. Almost all the user interface is just buttons, very much inspired by the jackal.
While tuning, i observed that only one digit if the frequency read out changes most of the time. So, the displayVFO routines figures which digits need to be repainted and updates only those. This routine is probably what makes the interface usable with the 8 bit power of the Arduino Nano.

Ooh…a thing that reads the screen in morse? That’s half the battle toward eyes-free operation. The other half, of course, is some additional way to control besides the built-in touch screen interface, like a programmable keypad. Seems to me there were a couple of implementations of this floating around. Do please elaborate.

By morse reader, I actually meant software that reads out the screen in morse code.
I had fooled around with many morse decoders. Nothing really works on the bands. CW skimmer is the only thing that works under contest conditions.
So, if you want a morse code decoder that really works well, can adapt to any radio and needs no special hardware, then, spend a month, 20 minutes a day and practice at 30 wpm.

This is very exciting. I have been thinking a long time but have not purchased one because I was afraid that the soldering and wiring instructions would be confusing. There have been many posts by confused builders.

This sounds great. Is there a morse code decoder built in or coming soon ? Your earlier post said " I have added a morse reader already. I shall finish integration to the user interface soon."
Please let us know when that is incorporated. I am unlikely to upgrade the software-firmware once it is working and that would be a very nice feature.

Great idea on the calibration with a known station signal for people without test equipment.

Thank you very much for this great upgrade !
