Maybe this new thread can be helpful for everyone who wants to build the ICP for the Viper and doesn’t have a lot of knowledge, like me, for writing code and it is a really cheap solution.
This is my first thread on any forum whatsoever, so if I made some mistakes, please forgive me.
Last month I bought an ICP for the Viper from Hispapanels for assembling the first part of my ‘desktop’ cockpit. In other words, I will only have the most important panels on my desk so I can cut back on the use of the mouse and keyboard.
For the ICP, I followed the thread from Tekkx and Hansolo for building a matrix and using DCS-Bios, so you can spare some pins on your Arduino board. This was a really helpful thread for getting started.

I got all my buttons and switches working, exept the ‘dobber’ or DCS switch gave me a lot of headaches.
After looking up and reading a lot of instructables, I endend up with MHeironymus joystick library. So I bought an analoge joystick (1€ in China), an Arduino pro micro(32u4 chip, 6€ for a clone) because I thought it was the easiest way of making a ‘dobber’ switch.
After a lot of trial and error, I have found a quite simple solution thanks to Aldrinos for asking and MorganS for providing a working code on the Arduino forum.
If you use the Arduino micro with the joystick library it will show up in windows as a game controller and you can assign any key you want for 'up-down-rtn-seq' in the controls menu in DCS. So basically it adds an extra input device, besides the keyboard and Hotas in DCS.

I’ve added the first 4 lines myself. I believe they are necessary for the Arduino to show up in windows 10.
The letters ‘h’, ’d’, …. in Keyboard.press('h'); is one of the keys I assigned in DCS control menu.
This is my working code:
#include <Joystick.h>
#include <Keyboard.h>
// Create Joystick
Joystick_ Joystick;
const int pinXAxis = A0;
const int pinYAxis = A2;
const int middleX = 512;
const int middleY = 512;
const int leftThreshold = middleX - 256;
const int rightThreshold = middleX + 256;
const int upThreshold = middleY - 256;
const int downThreshold = middleY + 256;
const int hysteresis = 32;
void setup() {
}
void loop() {
int rawX, rawY;
rawX = analogRead(pinXAxis);
rawY = analogRead(pinYAxis);
if(rawX < leftThreshold - hysteresis) Keyboard.press('h');
if(rawX > leftThreshold + hysteresis) Keyboard.release('h');
if(rawX > rightThreshold + hysteresis) Keyboard.press('d');
if(rawX < rightThreshold - hysteresis) Keyboard.release('d');
if(rawY < upThreshold - hysteresis) Keyboard.press('y');
if(rawY > upThreshold + hysteresis) Keyboard.release('y');
if(rawY > downThreshold + hysteresis) Keyboard.press('r');
if(rawY < downThreshold - hysteresis) Keyboard.release('r');
}
