Hello everybody!Did anybody realise the radiopanel from a A320?Only 2 7-seg. display for active and standby freq.?thankspeter

Only 2 7-seg. display for active and standby freq.?All of the pics ive seen of the A320 radio panel shows that it has 6 displays for each. Maybe ive misunderstood what you have ment. http://www.airliners.net/open.file?id=180318CheersGaz

Sorry forget about my first post. Not sure with fsbus. I use the the maxim 7219 chip. Sorry again.Gaz

Thats correct!You see that in the airbus is only 2 displays needed to schow the different frequenzes. You can select the displays with some buttons!i hope someone can help me!peter

Hi Peter, I just had a look at fsbus.deYou are correct in assuming that you only need to use 2 controllers per radio panel. To have the full 6 digits some people hardwire the first digit to 1 which leaves the 5 digits on the pcb for the controller to change, however if you just drop the last digit altogether to have 5 displays it makes no difference. Once you wire the button into place and press to change from standby to active the software will change the displays.Also do a search in this forum and have a look at this topic#3679, "7 Segment Display / Fsbus"Hope this helpsGaz

Sorry but i don

No ProblemThe fsbus display PCB contains max 6 controllers (Microcontroller and display board)with 5 7seg. on each. For one radio panel you would only need to use 2 of these controllers. If you wanted to build your A320 panel with 6 displays like they are on the aircraft then Digit No1 would be hardwired permanently as a 1 and would not be part of the board because the first digit is always the same and doesnt need to be changed. If you only want to have a five digit display (most common) then FSbus rounds the last digit eg: 119.550 would become 119.50 because F/S only recognizes 2 digits after the decimal point at the moment.Gaz

Thanks for your help but this is not the problem!Look at the pic in one off the answers!You see that there are only 2 7-seg.-elements to display the activeand standby frequenzes.Now i want to know, is there anybody who realize this?Or did anybody have an idea on witch way i can realize this!I mean the routing and programming in the bus.I want to touch the vhf1-button and see in the 1. display the activ frequenz and in the 2. the standby frequenz. then i push the nav2 button and see the frequenz of vhf2 in the display!I hope someone understand the problem.many thankspeter

I understand what you mean though.* You have *one set* of active/standby displays: 131.25 <> 119.10* You have COM1, COM2, NAV1, NAV2, ADF, DME, FOO, BAR... buttons* When you press "NAV1" button to make it "active", it shows NAV1 freq.* When you press another, it shows that radio instead.So basically you have one "display" that shows whatever of those radios you want to show, one at a time.As far as I know, this does not work yet, but if I remember correctly, Dirk was saying this was one of his design goals, since he is building that kind of a radio himself too.Best,Tuomas
