Hi so I have taken this little Arduino project thinking it's gonna be simple but turned out to be way more difficult as I told my teacher I've made a small arduino project using a DHT11 sensor and an I2C 1602A display and he told me I could get this class grade by making a project where I display 2-3 letters on the I2C display and I have not to use libraries would someone like actually help me do it? because I can't find anything and all he told me was to use the HD44780U datasheet and learn how each bits can make each letter or symbol or stuff it's just so confusing and I wish someone could help me do it as easy as possible because I'm not trying to major in Arduino and just trying to pass this class
I suggest you first get your project to work using the libraries and then replace the library functions with your own code. That way you know all the wiring and power are correctly operating.

That is evidently the point of the "no libraries" part of assignment. You are supposed to learn how to read a data sheet, which is a very valuable skill.
Show some effort and make a good impression by taking the data sheet to the teacher and ask him or her to point out the important sections, and give you some guidance on how to read it.
I gotta say I kept looking at it over and over again I still cannot get how to understand it and deadline is monday for this crap and I might trash it and just do the normal task he gave us without arduino as I'm absolutely confused on how to use it and I try to understand it yet I can't
If you look at the test program in this link (post #41) , there is an example of code which also writes directly to an HD44780 display driver without using a library: LCD 1602 (and similar) databus sniffer - #41 by 6v6gt . You'll probably still have to use the datasheet https://forum.arduino.cc/uploads/short-url/uGDA5ZAHZnkrMk50pl1ZAY6hZsU.pdf to understand it though.
My point is just getting over that class. I'm not even 1% interested in learning arduino it just happened to be a tool in this project and I require far more assistence than you could probably imagine....
Then I suggest to drop the class.
I would honestly but it's not an optional one.... and It's either I get this arduino to work which is likely not to happen or I just stick to his assignment and I hate coding overall... so I just was wondering if any of you guys here are willing to help me get this thing done if not I'll just get rid of it and probably donate the arduino to a tech geek because that's not me and will never be....
I do have the whole one yeah but It's so confusing I'm looking at something I hardly try to understand
I might have found something to atleast guide me in the direction and give me a starting point https://www.youtube.com/watch?v=8ZsUcUAsL3I
I’m guessing you’re going to use ‘parallel’ mode. so the next choice is to use 4-bit or 8-bit mode. when talking to the LCD.
There are hundreds of examples out ther using C code.
Sadly, thrsr are things you need to understand for this project,
Do you have any idea how I implement the I2C unit as well? I can't remove it off the display and deadline is tomorrow and I'm craving to finish it as long as someone can help me understand how I also implement it and get it to work
