I just got the v4 of Keil. I am programming with a 8 bit 8051 micro controller. I was wondering if there are any good books or materials that will help me understand programing alot better. I look at the code and the memory information and I am clueless. I have been trying to read and talk to others and still no help. Please Help!
Thank You
Zack
Thank you so much! I will review over this, I have been having a problem with understanding what the code is actually doing... Im currently working on a problem trying to get an LCD display working and checking for a busy flag after each process or what not, i was given a flow chart to go off of.
OPTREX LCD

Note: BF should be checked before each of the instructions starting with Display OFF.
This is the stuff in the flow chart above... but hopefully somewhere in what you posted will get me to understand.
THank you again! Zack
What kind of help do you need, exactly?
I will review over this,
NO. You should _start_ with the links given you.
I am reading all of it now... This tutorial on 8052 is alot easier to understand than any of the material i have read in books so far... There is a couple of things im kinda fuzzy on, ill keep reading and mabye it will become clear.
Just wanted to express my gratitude!
