Hi,
under https://github.com/BenediktO/libsigrokdecode.git I uploaded the HD44780 decoder I am developing under the branch add_hd44780. I hope that I made less errors than with the 7-segment decoder. The decoder supports LCDs with the common configurations from 1x8 to 4x20. On top it supports both possible charsets, for some (japanese) characters i was not able to find a unicode representation. It provides a simulated display that displays the current content of the display. Note that it supports both 4 and 8 bit mode, but since i only have an 8 bit logic analyzer, I was not able to really test the 8bit mode. Custom characters are displayed as "CC%d" with %d in range(0, 8). In the sigrok-dumps repository are already some example files, that i generated with an Arduino and various displays. The Arduino sketches are based on the example Sketches of the LiquidCrystal library. I could verify that the displayed output is exactly the same as the predicted output of the decoder. Except for the (rarely used) read command of the display all commands are supported and tested.
