Hi to all Civic owners,
I am running a project to manufacture a custom hvac audio display for my non satnav civic mk8(2010 Model)
I am planing to use a 2.8 Nextion HMI TFT LCD display and a microcontroller board like stm32 or arduino
İdea is simle,
1) connect the microcontroller (stm32 or arduino) to the audio display connector of the car
2) read data coming to the connector pins when a hvac button is pressed or released
3) send a command to the TFT lcd to show an icon or text depending on the value of data
my tft lcd sketch is like below

and this is the pinout diagram of original display

it will be fitted in the sub audio display section of a factory satnav screen and I will use the main satnav screen for something else (reverse cam, video, maybe an external navigation)
I know how to run tft lcd, but I'm not sure which pin to read and how to read tha data (is it analog, digital, voltage, resistance etc)
If I can get some help about it, I will share everytihg I got about this project for everyone willing to try it
Main screen task is already completed( the main screen allways shows navigation interface even if you switch to other menus on the head unit):

sub audio display is the last task
