i use this boar, site have scematic and how working.

http://embedded-lab.com/blog/introducing-a-new-serial-spi-8-digit-seven-segment-led-display-module-using-max7219/

but i take out 4 first digit left side and need use only 1 digit closely whit resistor show number 1.
and MF use right side 4 digit to change frecfensy number.
i no know how working but i think good, and DP (desimal point) working fine 8 digit board what i has use.

photo my first test, whit encoder

my radio com-nav board proplem solved, before i use 8-digit max7219 board and think how made 5 digit board,
no proplem ,take out first 4 digit and wire new 1 digit in to board,
or orden max chip led matrix board

i orden new board.
and yesteday wire to board new 4 digit + 1 digit 7-segment,
connect to chip pin ABCDEFG to 7-segment and D12345 to common, test show wrong side all numbers, i change wires D54321 and show all numbers right
D 4321 connect to 4 digit 7-segment ok, and then solder 1 digit to wire same ABCDEFG AND D5.
led matrix board up row must conned to D1,C,E,D4,dp,D2,F,G and down row connect to D3,X,D,X,B,A,X,D5 (Xnot connected)
and 7-segment wired to
4-digit
D4,A,F,D3,D2,B
E,D,dp,C,G,D1
and 1 digit wired to
same ABCDEFG but D5 common cathode.
and working fine 5 digit whit led matrix board max 7219 chip. this made 4 time and you have radio-nac panel. add fregfency change button standby and ready.
Same can do 8-digit max chip board too.but i do new wired to led matrix board wiring this.

some photo if can see, i test first time

Hi
Can anyone explain to me how I can connect a 4 digit one to Arduino ?
I don't have CS in the 4 digits, generally on the 7 digits you have 5 ports but in 4 digits it has 4.

By the way I'm talking about TM1637

@ bhrzk

I think Mobiflight do not support 7 Segment Displays with TM1637 chip.
You have to use Max7219 !

Sorry if i missunderstood youre request.

No sir, I guess you are right.

today hAS time test power line, all working fine

good job!

good job masawee!!!

someone has thought about the possibility of linking 64 individual LEDs, to use as annunciator, via MAX7219, to avoid resistance?

I tried with link2fs and through code works fine.

I just try to connect seven segment with FSX. The display appear 025.12 whereas on FSX occurs 125.12. Is anybody know why? Even I modified some number setting, but the result remain the same. Please, help me. Thank you..

You have to add 10000 in transform box on the first tab (FSUIPC)

Code:

$+10000

If you look at the FSUIPC Offset documentation it will tell you that the leading 1 is not part of the offset because it is always 1.

Please always also check the example file that is in your /examples-folder of the MobiFlight installation directory.

Thanks lot Sebastian, now its work. Just would like to ask you once more. Refer to sample you describe can I make same function but for altimeter, heading, etc.

Thanks lot and have a nice weekend.

See this posting today.....

YES. I think about! But I think thats not profitable..... You need to build a 8x8 Matrix and wire it ( Maby it´s posible to hack a 8x8 prebuild Matrix Board but i don´t find something like that in the web)

So... Yes it´s cheaper as you use 2 Arduinos..... But it´s a lot of work. and it´s not posible with Mobiflight at the moment.
Sumary i think it´s easyer to set 64 resistors..... To much work to wire this and config that stuff.

Hi Pierre,

Wich matrix is this? Can you show me where you buy it?

I intend to build the NAV, XPDR, COMM and ADF Boeing radios and don't know wich itens to buy (just know that I have to buy Mega2560, ex.)
