Hello, I'm trying to attach a VGA to the arduino zero board. I was curious if I need to use a logic leveling to go from 5v to 3.3, Or do I wire it directly? What I mean is I know in some cases VGA is at 5v or at least I think it is. I was curious If I need to bring anything down besides the resistors I need to add to it.
That’s what I’m thinking. But then again I searched online and saw others just having resistors. Well not on the zero board. But with the due board that has the 3.3v logic lines as well.
Did You search for how many that survived longer then it took to post the material?
The internet provides a lot of pure amateur gutter work. Please don't refere to that without links.
The thing is most people are using between 270ohms resistors to 320ohm resistors. If I have to bring it down to 3.3v logic level. I don't know how with using them resistors.
Being that the esp32 is using 3.3v logic level and the zero is also using 3.3 logic level. I thought it would be the same in resistors value. That is what I was assuming.
I can not find anyone who is using the arduino zero. Most people I see online are using a uno or mega board which is using a 5v logic level that is what the VGA is needing.
All VGA from what I read and heard are using 5v. When at 5v they use a either 270ohm resistor or a 320ohm resistor. from the VGa to the arduino. But at 3.3v I know it needs to be converted down from 5v to 3.3v but my own thing is do I still need that 270ohm or 320ohm resistor to be added?
Edit: I think that is where I'm getting confussed at and confusing others and for that I'm sorry.
