I am unable to scroll the message on lcd. Help needed..
Welcome in the forum!
You will have to do that (depending on LCD) manually, saving the text on line 1 and when scrolling writing the text to line 0
Basically use a char buffer that holds message. Then use a variable
to indicate which column to start write. Perform the first message write,
char at a time, until you hit display end with a counter variable) then
finish remaining chars at beginning of display. Then inc the column start
variable, testing ot for overflow at end of display, and resetting to 0 if necessary.
Wait for a period of time that controls how fast update you want the scroll to
run at. If message shorter then LCD row then either buffer it with " "s or
keep track with a variable and write the balance in " ".
Can I use more than 8 custom characters?
When you are using the LCD module that comes with the CY8CKIT-050 the answer is "NO".
The component in Creator is based on the Hitachi/Renesas 44780 controller. From its
Character Generator RAM (CGRAM)
In the character generator RAM, the user can rewrite character patterns by program. For 5 × 8 dots, eight
character patterns can be written, and for 5 × 10 dots, four character patterns can be written.
