CC2541 interface with Parallel LCD (2x8 display)

[Kick]

Hi,

How to interface CC2541 with 2x8 parallel LCD? Have anyone experience on this?

1. Direct interface is possible?
2 or should I use SIPO (Serial In Parallel Out) for conversion? then I can connect to SPI of CC2541

thanks

You can use a direct interface either with 4 or with 8 bits (8-bit is somehow faster but requires more I/Os, look on the data sheet of your lcd) it will work just fine. You have enough I/Os in your chip so unless they are used for something else you won't have a problem. In software part you have to write small routines to initialize and communicate with the lcd. The controller for the lcd is ST7066U which is similar if not the same with standard HD44780. There are also examples on the lcd data-sheet.
