    Hello,

    I am trying to write my own library for the usual 2x16 LCD. So, I downloaded the datasheet from: https://www.sparkfun.com/datasheets/LCD/HD44780.pdf

    As a start, I'd like to write a function that sends an instruction. But I don't kinda get this diagram:

    I know there are dozens of examples out there but I'd like to know how to catch a fish.

    It seems to me that I should first set E to high, then send 4 bits of data, then set E to low. Is this correct? E is being set to low in the middle of sending 4 bits of data confuses me. How long should I keep sending the data? How long should E stay in high state? Should I wait for some time before sending the second 4 bits of data?

    I have these kind of questions as I am new to electronics. I would very much appreciate if someone can explain how to read these kind of diagrams.

    Thank you
