Kenpilot Posted February 19, 2022 Share Posted February 19, 2022 (edited) Hey guys. I'm fairly new to the arduino world and DCS Bios and I'm building a CDU for the A10C. Obviously the CDU panel uses a lot of tactile buttons for the panel and I know typically you are supposed to use an external resistor when wiring a button, but that would be A LOT of resistors for the panel. I've read where the arduino has sort of internal resistors where you can program the input pin to use these "internal" resistors so you don't have to wire a bunch of external resistors. Does anyone know how to include this program language in to the DCS BIOS program language for the CDU buttons? If anyone has built their own CDU panel using arduino, DCS BIOS and the internal resistor programming language for all of the buttons, could you please copy and paste your program so I can use it? Or at least see how to write it? I would greatly appreciate it. Obviously I might have to change the pin numbers depending on which arduinos you use, I know how to do that, I just don't know how to incorporate the arduino internal resistor program language with the DCS BIOS language. Thanks!!

No1sonuk Posted February 19, 2022 Share Posted February 19, 2022 DCS-BIOS automatically applies the INPUT_PULLUP mode for button inputs when you use the applicable control reference code. For a CDU, though, you'll probably want to use some kind of matrix, which requires more coding. Link to comment Share on other sites More sharing options...

Vinc_Vega Posted February 28, 2022 Share Posted February 28, 2022 Hi Kenpilot, you still want code for a button matrix? I adapted the code from that forum (credits within the source code below) to my needs. Don't know if the internal pullup is already / still on by DCS-Bios, but that worked fine for me.

Rapti Posted March 6, 2022 Share Posted March 6, 2022 I have done the CDU without any resistor for the buttons. Just for the LED's Link to comment Share on other sites More sharing options...
byteman59 Posted March 26, 2022 Share Posted March 26, 2022 Am i to understand that i am to use NO pullup resisitor for switches. Use resistors only for LED? Link to comment Share on other sites More sharing options...
Vinc_Vega Posted March 26, 2022 Share Posted March 26, 2022 Yes, if using the DCS-Bios library the pullups should already be activ for standard inputs.
