I am trying to use my backup camera display to act as a 4-6 gauge display in my car, Im trying to currently figure out if i should make the code for a composite layout and figure that out or if I should make the video out of the arduino in I2C format and convert it to analog format.
Thank you guys so much for the help in the past and information all around!
Is there a digital to analog converter or other hardware that can translate the image file sent through I2C to analog? Im just trying to see what is possible and with what hardware is required to make it happen
The reason i ask is as im unfamiliar with rpi, my understanding of its setup and bootup after programming is the rpi is clumsy to start up and shut down as used in an automotive application wheras the arduino is set it and forget it. As i was planning the composite video from the arduino is a bit clumsy however i think its enough to do what i need it to.
I2C is slow, not intended for data transmission over wires of any significant length, and limited to very small amounts of data in a packet. You will not be able to make a video stream from I2C data, but with a significant amount of effort, you could transmit and reconstruct single image frames.
The chance that you will be able to get an Arduino to produce the required video output is close to zero.
But if you want to try, you first need to know the format of the video signal. It could be standard NTSC or PAL, or proprietary. Ask the manufacturer of the camera.
Well i attempted a dvd player rca as seen in the picture above the big bang theory on the mirror so its not proprietary however i dont really know a ton on composite video. Being that the arduino fits all the requirements i have with this one exception is why i am attempting the path im on otherwise id just run rpi as a dash head unit and make the mirror just a second screen(if thats even possible) which would probably make my life much easier
