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
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.
