Will the character LCD be enough or you will go for graphic LCD? In case of graphic LCD, you can go for serial interface type GLCDs, especially the COG type with a very small size. Otherwise a small adapter can be made which will accept I2C input and convert it to parallel data stream for the LCD. For the scope of the project as it is now, a text based display will be more than enough. I mentioned earlier that I was interested in using serial for the LCD, but I've opted to do something memory-mapped in parallel instead. This way I can leave the serial channel open for development purposes. I purchased a PVG240602A panel with toshiba text-based logic (it will do a couple different fonts/sizes, but still text-only) Gopal Amlekar said:
For the keyboard, I remember I had seen one application note (AN434) from PHILIPS for interfacing to 8051. I will search it and send to you if you want. That would be great! thanks. |
