Hi Folks,

New poster here - I'm building a GA Cockpit and harve started with the Radio Stack.
I've got 8 x MAX7219's and 8 Digit 7 Segment LEDS - which are working fine (now i've found the soldering issues!)

I'd like to display 6 digits instead of the usual 5, by calulating the final digit. Something like an if, then statement... ie last supplied digit = 0 or 5 then 0, else 5) for 00(0),12(5),25(0),37(5)etc..

Is this possible ?

Thanks

Greg

U can divide the number by 5. If result is integer then set to 0 . Else set to 5. That the logic.

Do we talk about the 25 Khz Band or the new 8.33 Khz Band ??

FSX and P3D work already with old 25khz band.

In That case your right... the Frequencys ends with "2" and "7" should normaly have a "5" on last diggit. Like 125,77 is normaly 125,775

But as i know that was a problem in Real Aircrafts in the past, too.... In case that the last number is always the same ( 0 if number before is 5 or 0 ... AND 5 if Number before is 2 or 7)
they not include a 3.rd display and show it on a 2 Diggit Display Finaly.

To solve this you need a MODULO like thatchi say... So "$%5" result in "0" if Frequency is .x5 or .x0 and it result in "2" if Frequeny is .x2 or .x7 .

a condition can be if($%5=0,$*10+100000,$*10+100005)

Example A : Frequency 123,45 (FSX) Should be shown as 123,45 ... RAW FSUIPC Value = 2345
2345 MODULO 5 = 0 ... So the THEN Command is working ($*10+100000) 2345*10 = 23450 ..... 23450+100000 = 123450 .... With a Decimalpoint on Display its 123,450

Example B : Frequency 123.47 (FSX) Should be shown as 123,475 ... Raw FSUIPC Value = 2347
2347 MODULO 5 = 2 ... So the ELSE Command is working ($*10+100005) 2347*10 = 23470 ..... 23470+100005 = 123475 .... With a Decimalpoint on Display its 123,475

Try this out !


NOTE: If you work with 8.33 khz Band like new Aircrafts in Real.... This is NOT possible in FSX directly. I Remeber we talk about that in the past but i not find the topic.
Maby Stephan still remember that ! Not remember if we found a solution to convert the FSX band into 8.33 ... but i not think so !

The 8.33 kHz grid is not possible in FSX.
Maybe it is possible in P3DV4x.

Example:
121,000 MHz
121,008 (33)
121,016 (66)
121,025 (00) # actually (99)
121,033 (33)
121,041 (66)
121,050 (00) # actually (99)
etc.

If FSUIPC (in the 64-bit version) still only got 2 bytes (1210), a true frequency representation could not be displayed in this grid.
Enthusiasts may then be inclined to represent the complete 8 digits
