DCS-BIOS A10-C CDU Brightness Value

[maciekish]

Hi, I'm having a hard time finding the CDU backlight brightness value from the sim. I can only find the rocker-switch which is a simple increase/decrease:

I'm currently keeping my own brightness value in memory on the Arduino but it gets desynchronized when the game reloads. Is the actual value from the sim available in DCS-BIOS?

Using this for now:

// Backlight Control via pin 46, requires a hardware mod to the TFT shield.
unsigned int brightness = 255; // The CDU in DCS starts at max brightness, using the same initial value help with synchronization.
void onCduBrtChange(unsigned int newValue) {
    if (newValue == 0) {
      if (brightness > 25) {
        brightness -= 25;
      } else {
        brightness = 0;
      }
    } else if (newValue == 2) {
      if (brightness < 230) {
        brightness += 25;
      } else {
        brightness = 255;
      }
    }

    analogWrite(46, brightness);
}
DcsBios::IntegerBuffer cduBrtBuffer(0x10fa, 0x0003, 0, onCduBrtChange);
