problem with LCD blink cursor

04A236

Hi all,

having a little problem in getting the cursor to blink with "LCDCMD 1, %00001111"...
wanted to turn on both the block and underline cursor...


But what came out on the display...·
a second digit outputed to the LCD would erase the previous digit...·
there is an increment in the display though...·
meaning the display does move along with each new digit output to the LCD...

Anyone who faced such problem and found out the reason...
Please guide me along?!!!

Thanks in advance,
Rita

Hmmm ... according to the Hitachi docs, the display control byte is setup like this:

% 0 0 0 0 1 D C B

D = Display on/off (1 = on)
C = Cursor on/off (1 = on)
B = Blink character under cursor (1 = blink)

So your code should be correct -- at least that line. Perhaps you should attach more of your program.

Hi Jon,

thanks for replying...

The·attached is the part of the program that i'm having problem with...
It's located in program slot 0...

I suspect that the program is reseting itself clearing the LCD display over and over again...


Please advice!

Thanks a zillion...

PS: sorry for the messy-ness of the program..

regards,
Rita

HEY! You CAN just attach a file to the post now, you know.

You don't have to clutter up the thing with pasted-in code.

Thanks for your attention.
