Teensy LC Hydralic Panel
« on: October 10, 2018, 04:52:42 PM »
Hi!

Here is my sketch for my Haudralic panel for the Zibo 737 and X-Plane 11 using Teensy LC.

const int PIN_KORRY_PUSH_TO_TEST = 4;

const int PIN_KORRY_LIGHT_ELEC_LOW_PRESSURE_1 = 3;

const int PIN_KORRY_LIGHT_ELEC_OVERHEAT_2 = 17;
const int PIN_KORRY_LIGHT_ENG_LOW_PRESSURE_1 = 16;
const int PIN_KORRY_LIGHT_ENG_LOW_PRESSURE_2 = 20;

const int PIN_SWITCH_ENGINE_1 = 15;
const int PIN_SWITCH_ENGINE_2 = 19;
const int PIN_SWITCH_ELEC_1 = 18; //Check these, the ground might be touching
const int PIN_SWITCH_ELEC_2 = 21; //check these, the ground might be touching

Teensy LC Hydralic Panel

Hey Peter,
Looking at your code it looks like you control the brightness of the annunciator with a dataref related to some kind of lightning control knob in the Zibo aircraft. Is that correctly understood?

Are you limited to use the analog pins of the teensy? Are all the annunciators connected through a ULN2803A?

BR.

Yes, its controlled by the dataref of the backlight.
Advantages with this is that you dont have to link backlight and the know by hardware / cables.
Just torn the know and read the values from the Logic in X-Plane. Great.

You prob know this now,

I am limited when it comes to the large panels, but with our PCB i plan to use double PCB and 4 ULN2803A. Then the pins and ULN2803A should be enough. =)
