Great! Honestly I don't think it would be too much work. As I understand it, we only need to add a new annotation type (maybe SRD_OUTPUT_IMAGE_%s with %s being the image format) to libsigrokdecode and have your PD emit it. libsigrok itself is unaffected and honestly I don't know if sigrok- test needs to verify that the image output is correct. I mean I guess there would be a benefit to do so but that could be done later if desired. -Soeren > > 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 > > This solution would solve the problem with the custom caracters too. > > Benedikt > > > > 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.
