Instrument development - E28 - Character display

[@harryonnekink3686]

Great video. Important step to show the COM and NAV digits on the display. However the last steps to perform this, is still a riddle to me. Cannot find in the API any scripts how to model AM enabling to show the numbers. Any suggestions?

[@ralphrietveld]

I'm not sure what you're asking. But you can use our forums for any questions on scripting.

@@ralphrietveld Hoi Ralph, Ik ben inderdaad op zoek naar hoe je hardware displays kunt aansluiten op Air manager, zodat je de frequenties dus ook op je display ziet die je vervolgens kunt inbouwen. Maar ik kom er via AIr Manager zelf en de KZbin filmpjes niet uit. Dus ik ga maar eens naar het forum. Dank voor je antwoord.

[@ralphrietveld]

Ik geloof dat er al een hardware functie voor is. Als je in de Home tab op +Hardware klikt en zoekt op com of nav dan vindt je het waarschijnlijk wel. Kwestie van de gewenste source selecteren, de pinnen en klaar.

One question, how can I shift numbers 2 spaces to the left? I want frequency 133.750 showing towards the left of my 8 digit segment display. Someone put me an example please

[@ralphrietveld]

You'll need to use string.format("%.02f", frequency), or a different formatting.

Any plans to do a stepper motor video ?

[@ralphrietveld]

I think there is one in the video series, but I might be wrong.

[@fatcharlieuk]

Great video thanks. Any further development for LCD displays? Or the ability to send the relevan characters to an Arduino card running an LCD display using the lcd.h library? My cockpit is bult around 16x1 and 16x2 displays and although I could convert it would be easier to just use what's there! :-)

[@ralphrietveld]

I'm not entirely sure what you mean, but we are not going to support more displays than these. You can always use the message port in combination with your own Arduino sketch.

[@fatcharlieuk]

​@@ralphrietveld I mean 'LCD displays' as opposed to 7-segment digits. Like these: content.instructables.com/ORIG/F6C/X2L6/IBHRNLW4/F6CX2L6IBHRNLW4.jpg?auto=webp&frame=1&fit=bounds&md=a554a290f5c2d2f8e94d36b0f082add9

@@fatcharlieuk That can be a HD44780 which we already support: siminnovations.com/wiki/index.php?title=Hw_chr_display_add#HD44780

[@fatcharlieuk]

Ralph Rietveld thsnks fir getting back to me so quickly! I need to read the manual better :-)

[@ralphrietveld]

@@fatcharlieuk there's a lot in there so it's easy to miss something.

Excellent, I have some trouble when daisychain max7219 displays, but in my test I try to send que complete 16 characters to the display, now I see you send the data individually, could be that my problem? Is possible to send 16 chars to 2 max7219 without trouble or is better to doit one by one?

[@SimInnovations]

Hi Javier, you have to send those individually. So 8 per display. Check out argument 2 here: siminnovations.com/wiki/index.php?title=Hw_chr_display_set_text hw_chr_display_set_text(display_chr_id, 0, 0, "12345") hw_chr_display_set_text(display_chr_id, 1, 0, "54321")

Unless you have fixed it, the number of chained modules actually matters. If you have more than 4 modules, let's say 6, and you write there 6, modules don't work properly, they freeze and stuff. You shall write there 8 even if you have 5,6 or 7 modules chained.

[@SimInnovations]

Still in the 3.7 beta. But on the list to fix.
