1602b display line problem

hey guys

i am using the 1602b lcd connected to a NI-speedy 33 board, and trying to get it to work.

but i am encountering a problem that when it tries to switch to the 2nd line, it takes 25 inputs
before the character actually displays on the screen in the 2nd line

how do i fix this issue, which i want to have the character shows on the 2nd line of the lcd
immediately after the end of the 1st line

thanks guys

If you look at the data sheet, on pages 8 and 10, you will see the addressing scheme for the character locations. The 2nd line is addr 0x40~0x4F, so to set the cursor to the 2nd line you have to issue a command 0xC0~0xCF, before sending the text.
