Hello

Im having trouble Displaying correctly in the LCD.  The LCD controller is a Hitachi HD 44780, type PC4002. The problem I am having is that  what i want to be displayed,, it is very dim almost cannot see. I think because it is refreshing too fast and you cant see anything. I am using the CPU external Devices TLCD. 

The code that I am using to display something is:

LCD1_Cls();

LCD1_Home();

LCD1_DisplayString(" TEXT HERE);

and i am using V6.3  Coldfire v1  MCF51JM32VLD

any help will be appreciated thank you

Did you try adjusting the LCD bias voltage?

how do i do that?. But  i dont think its that. It only goes Dim when it is in a loop, and the refresh rate isfaster , so the characters are really dim.
