I'm using 2x16 dot matrix LCD. In the first initiliaze it's work fine, I can write at first line and second line just like I want, but when I do the clrscr command (control 01h), the LCD goes unpredictible. It's fine at the first line but when I do at the second line, It's not work. the character that I send at the second line it's never appears. It's not my program (I think), becase it works at the first time. I'm Also give the delay for my program, for 100 ms till 1s. It's still doesn't work

thank's
