    CY8CKIT-050 and Character LCD problem

    Mark Hastings

      Some of you may have seen a problem with the character LCD on the CY8CKIT-050 development board when running a system clock of 24 MHz or faster.  We found a timing issue in version 1.8 of the character LCD component.  To avoid this problem I recommend that you revert to version 1.7 of the character LCD.  You most likely will not see this issue on the CY8CKIT-001 since it has a different interface to the LCD.  The CY8CKIT-001 board has a level translator between the PSoC 5LP and the LCD.  The CY8CKIT-050 has 10K resistors on the data lines between the LCD and PSoC 5LP, which make it more susceptible to timing issues.

         

      To revert to an older version of the LCD or any component, right-click on the project name in the Workspace Explorer and select "Update Components...".  Find the "CharLCD" component and select version "v1.7" form the Available Versions column.  Select the Update check box on the right, then select the "Next" button at the bottom of the dialog window.
