Topic created by Jean-Marc Zingg Hi E-Paper Fans Waveshare has extended their range of small e-papers with SPI interface. These e-paper displays are quite easy to use, and Waveshare has wiki pages for them with complete information, schematics, pdf specification, and code example. Be aware of th…

Post created by Jean-Marc Zingg Version 1.5.2 of library GxEPD2 is available, install or update with Library Manager. added support for Waveshare 4.37" 4-color e-paper display 512x368 fixed __has_include test (for packages that don't support __has_include) added WIDTH_VISIBLE for correct graphics…

I can't find infromation. If it has a socket on the back of the board, can I connect it to esp32? Hmmm So there is a risk it may not work with your library.

2.7inch e-Paper HAT - Waveshare Wiki Usually, you connect it through the cable and connector. This goes through the level converters, but also works with ESP32, you may need to use the shortened reset pulse with GxEPD2. I am too lazy to look at the schematics to see if the RPi connector uses the 3.…

Bonjour Jean-Marc, First THANK YOU so much for your hard work on this project. I am wondering if you can help me with a specific problem. I have scoured this forum but cannot find a solution. I am attempting to use the ESP32 Epaper drive board by waveshare with an SD card reader to upload jpg file…

@paddy_wagon , Hi, This gets tricky. The method of post #2195 may no longer work with the actual ESP32 package. The ESP32 has two HW SPI channels, HSPI and VSPI. Each channel uses dedicated IO pins. But the IO pins used by a ESP32 hardware module (like e.g. HW SPI channel) can be re-mapped to diff…

Thank you @ZinggJM . and yes the epaper uses the HSPI outputs. The interesting thing is, I cannot even get the SD card reader by itself to function with the waveshare ESP32 board. I always get that same error when connecting power. When removing the VSPI pins to the SD card reader except for ground …

Hi @mitchel1029 , welcome to the forum! Yes, I can, if you donate one of these displays to me, or if you persuade Waveshare to send a free sample to me. Did you already check if this display works with the support for GDEW075Z08? //#define GxEPD2_DRIVER_CLASS GxEPD2_750c_Z08 // GDEW075Z08 800x480…

Hi @ZinggJM thank you for your quick response. I've bought it from amazon: Amazon e-paper 7.5 inch Yes i already tried the GxEPD2_750C_Z08 driver but didn't work. I only get e-paper busy messages. I can try persuading waveshare, or maybe arrange something with buying/sending it to you. Still in…

Hi, I have an issue with a Waveshare 7.5 3C epaper https://www.waveshare.com/pico-epaper-7.5-b.htm I connected it through the "Pico-ePaper-Driver-Board" to a RP2040 Nano Connect. This worked well, kind of. I had troubles with hibernation and waking up again after a power loss. I circumvented this …

@tux19 , Hi Christian, welcome to the forum! Thank you for the link! The Pico-ePaper-Driver-Board is new for me. But Waveshare is good at documentation: https://www.waveshare.com/wiki/Pico-ePaper-7.5-B and there is a link to the schematics: Pico-ePaper-Driver-Board.pdf On the schematics I found …
