I thought that someone here might be interested in this article on the "behind the scenes" control of character LCD's. Fascinating  8)



Reminds me of when microcomputers were programmed through the front panel with switches. Those were the days ...

Marco_c  - thank god for microcontrollers I say  8) It takes a lot of switch setting (and a 555 on the RS line) to even display a simple message. It certainly gives one a greater respect for all the heavy lifting that microcontrollers and libraries like LiquidCrystal do.


Ah the old EPE (Everyday practical Electronics) magazine article. Those were the days. I think I may still have a copy on a backup drive some ware.
Sorry for the noobish post but my knowledge is 10 years out of date!
