FPC Friends!,

Does anybody know a name for FPC code or component to attach a HD44780 display to the GPIO pinheader on my Raspberry ?

Unit might also do !

Greets, Wouter

PS: Not with I2C interface.

Seems like most examples are python based :o

The rpilcdhd44780 unit is written in Pascal, but it only implements an I2C interface.  It has a base class with the LCD command, so it only requires a derived class that implements the bit bang interface to transfer the data packets. There are several options to twiddle pins on a RPI.
