 · I want share with you my 1st Generic LCD HD (4 Bit mode) Driver for AVR micro controllers (write Pin of the LCD is connected to Ground), and it's tested and working. I mean by Generic, It's independent of the hardware connection of the LCD to the AVR micro controller,you can connect any pin of the LCD data line and control line to any pin on any port Estimated Reading Time: 18 mins.  · hdc - Main code file, you must add this to your project under "Source Files". hdh - Main include file, you must include this in any files you wish to use the library. hd_settings_example.h - This is an example of the hd_settings.h file that the library requires (and will try to include).Estimated Reading Time: 9 mins.

HD LCD connection using as few as 6 pins. Each pin can be on any port/pin, they do not need to be next to each other as in for example. R/W signal is optional. Two methods for LCD ready checking, check busy flag or delay. Multiple display support (up to 4). Optimized for minimum functions and code size. The HD controller uses Motorola compatible signal timing usingR/WandEnablesignals, which is different from the Intel compatible RD, WRsignals used be the AVR. The main difference is that the data transfer to/from the LCD controller is initiated using a single Enable pulse, the read or write mode must be selected beforewith. (Dot Matrix Liquid Crystal Display Controller/Driver) ADE(Z) ' Rev. Description The HDU dot-matrix liquid crystal display controller and driver LSI displays alphanumerics, Japanese kana characters, and symbols. It can be configured to drive a dot-matrix liquid crystal display under the control of a 4- or 8-bit microprocessor.
