Hi,
I made a simple temperature alarm with 89c52 and LMB161 1x16 LCD
the problem is the LCD displays data on the left 8 locations only, even increasing contrast affects only those locations, while the rest looks not connected.
I tried a small initialization program and manipulated all bits in data sheet, but nothing seems to have any effect on them.
I thought the display is bad so I got from another vendor JHD161A which is the same.
Repeating all steps now using the JHD161A data sheet, the same results
The only time I get full 16 characters, if I cut power then put on quickly several times, it may happen and stays that way as long as power is on, then back to 8 characters again.
I went to the vender asking if anyone solved that problem, he said, they normally buy 2x16 and this display is not sold often.
Please Help
