Hello Benedikt, Thanks for the PD!
One thing I've always wanted to do was to show images in PV that correspond with PD output - in other words, PD annotations in image form. This PD would be a great opportunity to work on this feature because the output of the device that the PD simulates is inherently graphical. Would you be interested in working on such a feature with us? What I have in mind is something very similar to https://eleif.net/HD44780.html - anytime your PD's DisplaySimulator changes the output string, it could generate such an image, send it out as a new type of annotation and PV could display it in various ways. Image generation could be done using e.g. http://github.com/Solomoriah/gdmodule or http://python-pillow.org, whichever has less dependencies and is easier to integrate into the MXE build for Windows. -Soeren On Sat, 2019-11-23 at 12:08 +0100, Benedikt Otto wrote: > 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.
