Serial LCD Application Note?
When I started using PSoC in April, I found what I recall was an Application Note showing how to use a CY8C24123A (among other options) to drive a parallel character LCD using a serial connection from a PSoC 5 (for example) so as to reduce the number of pins needed on the PSoC 5 for the LCD. Now that I have the chips, I can no longer find the Application Note, so it has either been removed (some of the cypress.com pages in my browser history no longer pull up documents) or I have not been able to repeat the search properly for some reason. Does anyone have this Application Note or a pointer to it? Alternately, does anyone know how to use the 8-pin CY8C24123A to receive a serial signal and also drive a parallel LCD; there must be some trick since the standard way to drive the LCD requires 7 pins. And yes, I now download and save interesting Application Notes!
