Hi Sharkfin61,

 

Thank you and a happy new year to you also, Glad to hear you have it working!

 

Yes that is an unusual error which I never would of guessed so I really appreciate you figuring it out, it may indeed help someone with a similar problem in the future, Cheers 🙂

 

Also, I might be wrong on this but I do remember reading somewhere that there is an error in the actual DCS export which causes the issue with the DIM/BRT rocker, so there isnt much that can be done about it yet unfortunately.

So glad, I got it working 😉

Now it's time to implement my AAP panel (to free it from the zero delay board first) and connect the two parts.

 

Here's the promised code:

Spoiler 

#define DCSBIOS_IRQ_SERIAL
#include "DcsBios.h"
#include "Adafruit_Keypad.h"

const byte ROWS = 9; // rows
const byte COLS = 8; // columns
//define the symbols on the buttons of the keypads
char keys[ROWS][COLS] = {
  {'a','i','1','4','7','.','[',']'},
  {'b','j','2','5','8','0','o','s'},
  {'c','k','3','6','9','/','p',' '},
  {'d','l','A','G','M','S','q','t'},
  {'e','m','B','H','N','T','r','u'},
  {'f','n','C','I','O','U','Y','v'},
  {'g','+','D','J','P','V','Z','w'},
  {'h','-','E','K','Q','W','}','{'},
  {' ',' ','F','L','R','X',' ',' '}
};
byte rowPins[ROWS] = {23, 25, 27, 29, 31, 33, 35 , 37, 39, }; //connect to the row pinouts of the keypad
byte colPins[COLS] = {22, 24, 26, 28, 30, 32, 34, 36}; //connect to the column pinouts of the keypad

PCB 2 - Electric boogaloo

I have redone the PCB traces manually. It uses substantially less vias all of which are all checked for best placement. It should be okay to solder and has passed DRC runs, though I must say that it is built at your own risk, I am no expert at PCB design!

 

Also added/changed:

- Added polygon pour to PCB top and bottom copper to make it more rigid.

- Added silkscreen pinout annotations on top and bottom layer.

- Changed key annotation from “SLASH” to “/“ to avoid confusion

 

The design uses x67 1N4148WS diodes (which are SMT so will be hard to solder for beginners!), x67 6x6x7mm Green LED illuminated momentary tactile switches, as well as a dual header 20 position connector on the back of the PCB which can be cut to size or built from 2 rows of single header strips. Builders of this project should pay close attention to the polarity of both the diodes AND the tactile switches, remember, the LEDs are diodes too!

 

Connector pinout: (NOTE: VCC is NOT 5V, it needs only about 1.8V to illuminate the panel, I am most likely going to add some resistors on the board to protect the LEDs in the not too distant future)

Note: The zip file provided should be able to directly import into JLCPCB fabrication service, I am unsure about other fabrication services but would imagine them to be very similar. Let me know of any issues no matter how small

 


Crosshairs, 

 

This looks great. Anyway I can get your Eagle files? I’d like to modify it so the switch matrix operates on 5V and the LEDs operate on 12V so they can run off my dimmer circuits? 

 

Thanks

Hi, I had been attempting to upload the schematic and board file but have been running into issues around the file size being slightly too big for github! i have opted to use google drive instead and here is the link to the .f3z file, I dont know how or if this can be imported into eagle so as a precation have uploaded the .sch and . brd files too as an alternative which should work with eagle, I hope this helps!

Great Project!

 

Can anyone create a BOM and CPL file?

If so, it is possible for me to order the PCB with SMT Assembly. 

This would be great, because i am really bad in smt soldering.

 

Thank you

Hello all,

 

With the exciting new release/update of the new A-10c II, I have decided it is time to build a functional CDU with an AAP as a single unit to place on my desk. I have long been interested in building a home cockpit but as of now lack the time to take on such an ambitious project, maybe one day!

 

To kick start this project, I decided to purchase a set of the brilliant acrylic backlit panels and buttons available from pcflights.com for the CDU, AAP and also the new ARC-210 radio panel (which will be a future project!).

 

The first task was to make a sloped enclosure for the CDU and AAP which was quickly made from scraps of aluminium I had laying around and sprayed black, next was to acquire all the switches and things needed for the job.

 

Perhaps the biggest challenge for this project is finding a way to mount all the 67 pushbuttons on the CDU to a rigid surface and then wiring it all up. after some thought I decided the best and only practical way to do this would be to have a custom PCB made for it. I took many precise measurements of the panel and made an accurate drawing for laying out the PCB and when I was happy, sent the files off to be manufactured a minimum quantity of 5 for £15 total, bargain!. It took some time but when they eventually arrived I was very impressed at the quality of manufacturing and quickly got on with the long process of soldering everything together with close observation of polarities!, the result:

IMG_1688.thumb.jpeg.1194035941fad20b22afaae01d24b355.jpeg

 

And a test of the lamps: (note: the V key isn't lit in this image but it turned out to be a single missed solder joint, always one!)

IMG_1699.thumb.jpeg.459c5130a40c63c97c1ba6220648a3da.jpeg

 

I plan to use DCSBios to interface with the module, as for the screen.. I am still figuring that one out 😄

 

More updates soon!, feel free to ask questions/give suggestions!

This is nice! Im having second thought on getting the Panel from pcflights as well or just make one myself with the 3d printer on the way. Can you share your measured drawings in CAD format? This github link have formats im not sure how to open.

Note: The zip file provided should be able to directly import into JLCPCB fabrication service, I am unsure about other fabrication services but would imagine them to be very similar. Let me know of any issues no matter how small

 

Is this possible on a 5x10cm pcb? or multiple pcb?,. what would be the best way for someone who cant do custom pcbs?

Hi,

Has anyone here ordered this PCB?  I know there's usually a minimum quantity order.  Looking to see who has extras?

I'm also noticing that the LEDs have no resistors?  Am I seeing this correctly in the schematic?  Looks like they are directly connected to +5V.   These green LEDs have a max forward voltage of 2.8 V.
