GxEPD2_PP is the GxEPD2 Arduino Library ported to Particle Photon It supports SPI e-paper displays from Dalian Good Display and the display boards from Waveshare that use these display panels. This topic is intended for asking questions, reporting problems and issues, and hopefully telling your su…

Thank you all for the feedback, it is a pleasure to learn that this library is useful and used on the Particle platform. Please note that I also have published a version of GxEPD2 for Particle, there is now a common source on GitHub, only the example(s) are different. The example for Particle is un…

[image] ZinggJM: It would be desirable to have a paged organisation of forum topics, as in the Arduino Forum, to avoid the unpleasant scrolling to the end of a lengthy topic! I find the here used Discourse approach superior to the paging approach. By means of the "scrollbar" on the right sid…

@ScruffR , thank you, I hadn’t discovered that “thumb”, it works well, and I can get fast to the end. I admit that I am prejudiced in favor of the Arduino Environment, as I use it daily, whereas I rarely use the Particle Environment.

[image] ZinggJM: @Norfeldt GxEPD2 has an example GxEPD2_WiFi_Example for loading bitmaps from the WEB. It uses the classes WiFiClient and WiFiClientSecure. It should be quite easily portable to the Particle environment, but I don’t have the time for it. I understand. Thank you again for maki…

[image] armor: Printing photos via (from) the internet would require 1. an http: site with 2. photos in .bmp format since conversion of .bmp to display on the e-ink displays is possible - just a lot of processing. Hosting .bmp files wouldn't be a problem - it's how to transfer it to the devic…

There are numerous httpclients in the library and now httpsclients so strike requirement 1. I have done a HTTP download to an SD card of a .bmp file but never got around to getting it to work for HTTPS. It should be possible to combine the GxEPD2_WiFi_Example (where all the hard work in processing…

Version 1.1.0+ added GxEPD2_PP_WiFi_Example, for bitmap download from web only download from http: works, would need help for https: only on GitHub, to avoid the need to increase the version for publish this is preliminary! [image] ZinggJM/GxEPD2_PP Particle Display Library for SPI E-Pap…

I don’t know your exact requirements, but maybe you just need the function showBitmapFrom_HTTP() from the GxEPD2_PP_WiFi_Example to start with.

Hi Norfeldt, I think you misunderstood my post.

An example is there for users to learn from and adapt to their needs.
I thought you could easily find out if there exists something similar to WiFiClient for Particle, or get help for this in this forum. I do not decline to help you, but you could start with searching on Particle.
