Neat :) I think this should be converted into a documentation page on occasion. |

Maybe augment with column for driving voltages? Could be helpful to some 2doms |

since support was added for the LILYGO T5-4.7 inch epaper board the list can include it? |

@markbirss the list is specifically for the displays. Maybe separate list for compatible boards would make sense but I think this is up to the boards author to link to this library. If you happen to know the serial numer of that 4.7" display, let me know. |

@2dom From the datasheets I've seen (and it was quite a few) the only exception is the ED097TC2, other displays all run at +22V, -20V and +-15V. The TC2 also seems to run just fine (at least for me) at +22V ;) |

@vroland how did you make the dable of display in readme.md? Did you use some tool to convert the table from excel github format? I would like to update the display list in readme but I am not willing to do it by hand :D |

with the M5Paper it is the ED047TC1 e-paper pictured below, maybe same or a ED047TC2 ? Good Display had 1 x ED047TC2 when I asked them if they have Parallel interface 4.7 inch e-paper Model Number：EPD_ED047TC1 | 540[email protected]" | Grayscale : 16 Levels | Display area : 58.32103.68mm | Display Driver : IT8951

Sure, makes sense

Ok, why not just put it in the "compatible since pcb version" column
with the M5Paper it is the ED047TC1 e-paper pictured below
Model Number：EPD_ED047TC1 | ***@***.***" | Grayscale : 16 Levels |

@markbirss the M5Paper looks much better than the Lilygo board, very nice thing. Definitely would love to get my hands on the schematic :) |

I hope to get some soon. They are driving the display with the IT8951E https://m5stack.oss-cn-shenzhen.aliyuncs.com/resource/docs/schematic/Core/m5paper/M5_PAPER_SCH.pdf |

Yea I just found it as well :) Very nice. They are using quite expensive parts, neither IT8951E or TPS65185 are particularly cheap... do you know what it draws in sleep? |

Im not sure, i see some discussion here https://community.m5stack.com/topic/2581/m5paper-epd-power-consumption/9 |

Seems pretty bad, I was suspicious why they don't advertise that :D Kinda defeats the purpose. |

@vroland definitely take a look at it, they managed to implement the touch screen which I imagine will be the same as with the larger displays. |

@vroland sorry, the largest epd i've seen is 9.7". |

That sounds awesome. My father has some dead Kindles and wanted to try it out. So if you ever sell them just send me an email to martin @ luckycloud.de and I will buy it from you directly. Still testing but so far works great, this is how the C++ class looks like: That way the users of my component can still use this parallel display same way as the others. I had only one little conflict, since Adafruit GFX that I use for the fonts / Graphics, uses the same structs as your class: GFXFont & GFXGlyph so I had to make a copy and rename them to GFXFontDiy & GFXGlyphDiy but that is not optimal.
But I'm really eager to try it out and make EPDiy work in the Inkplates too (I need to check first this hardware thing with the 100pF capacitor though) |

Hey @martinberlin,
Yes, I'm not happy with this as well. Originally, I planned to be compatible to the GFX fonts, but with large displays and the resources the esp32 offers I really wanted proper support for more unicode glyphs, anti-aliasing and compression for large fonts. So the implementations diverged.
Interesting approach they took there :D It would be interesting to play around with them, but I don't think I want to spend that money with plenty of working boards lying around. |

Thanks for your comments. I must say started like I year ago with C++ and to make embedded Firmware so still a long way to get the object oriented part right. |

Yesterday we bring back a very old ebook to life thanks to EPDiy. Just wanted to thank for the support! Note: I just realized selected the wrong model since it's 800x600, will try again using ED060SC4 |

Feel free to add it to the library once you have it calibrated :) |

It turns out that the kindle has the waveforms for the panel it used stored on the kindle itself ! Mine for example Kindle 4 [root@kindle scripts]# cd /var/local/eink/panel/ `[root@kindle panel]# more /opt/eink/scripts/pvi_barcode_table.txt E0D M01 97 # ED097OC1 https://www.mobileread.com/forums/showthread.php?t=259903 https://www.mobileread.com/forums/showpost.php?p=3488004&postcount=99 |

That sounds great :) Are waveforms for all the displays on there or just for your specific one? |

On mine just for my one display, but it seemed from the forum post I left
that at some stage the Kindle DX had other files also? I can't confirm

Good to know :) Do you want to submit a pull request or should I just add it to the table? |

You can add it to the table,use ED047TC1 ,don't need to change anything . |

@cxw0102 find similar one, there are usually alternatives. Try ED058... |

@cxw0102 The ED052TC2 is added :) |

Converting this to Discussions since I would like to keep Issues for firmware updates and resolving programming issues. Also dear @mcer12 a he original Dropbox link you placed has been deleted so I think it does not have a resin to be in the Issues section. I really like the idea to make a nice repository with details and datasheets of every supported displays. I know many are not supposed to be distributed but is no problem I will put it under my GitHub and gave the internet police 👮 |

I made this a while ago and kinda forgot about it :) Please take a look, maybe it will be useful.
