I am a beginner to C language... I have alreaady initialized the LCD in my code...How do i display a message("HELLO" eg.) to LCD? I want to use it in function void but i do not know where to start...I want to make it simple if possible...There are samples that i found but the samples are complicated...
"Look at your revision notes on page 3"
That's the trouble with having all your documentation separate from the source code!
Learn the habit now of always fully-commenting your code (with specific references to external documents where necessary)
For example: All functions should have a descriptive header; All variable definitions should clearly state their purpose, usage, range of values, units of measure, etc
eg
// Write a null-terminated string to the LCD void lcdwrite ( char *letter // Input: pointer to the string to write ) { while(*letter) { lcddata(*letter); letter++; } }
Think also that "letter" was not a good choice of name for the parameter, was it?
Ya that "letter" was not a good choice of name for parameter... But i still don't get any message displayed on my LCD...Not even a cursor..All i get are row of square dots...
Mr Alias,
go back and look at teech's notes. The code DOES work. I know, im using it here!
" i still don't get any message displayed on my LCD"
If you haven't corrected the call to the function, then it still won't work, will it?
Post your corrected code!
