Re: Starting a new multi epaper driver component for ESP-IDF

Anyone would be interested in using a component like this? I have a question about SPI. I started doing this EPD class following the Espressif master example (TFT) After an initial success sending data to a 2.13" Waveshare flex epaper, I could not communicate so far with other Epaper ICs- Can someon...

Starting a new multi epaper driver component for ESP-IDF

Hello all, I've started since 2 weeks to make plans and start a C++ component with the idea to make a multi-epaper component (Like GxEPD for Arduino) but for ESP-IDF. And I would like to know if there is anyone interested in: - Collaborating - Give C++ advice in case some my OOP is not right (I've o...

Re: ESP32 IDF Benchmark

Thanks Nicola, I'm actually building my first Epaper driver with Espressif's IDF so that will give me a steep learning curve. So when I get there I will retake this again and add your request to the list although I don't have any idea how to measure this, I guess opening an HTTPS connection and down...

Re: 2D graphic lib for ESP-IDF ?

Nice one! You just have one star more :) Please note that my fork does not include Arduino.h at all. I just had to include Print & Printable headers since Adafruit extends them. But could be changed if possibly by someone's pull request that understands better than me how a GFX library works. My ass...

Re: Port of Adafruit SSD1306 and GFX library for esp-idf

Here is my fork of Adafruit GFX to be used in IDF https://github.com/martinberlin/Adafruit-GFX-Library-ESP-IDF Please check the readme before trying since I had to add some Arduino related headers (Print & Printable, that maybe need extra refactoring to get them out). There is an implementation exam...

Re: Any reference example for GDEW0154T8 E-Paper LCD with ESP32 IDF

I wanted to announce that I'm working in a new EPD library similar (And inspired in GxEPD user-friendly approach) but without Arduino-framework dependencies. Only some classes like Print that are at the moment used by Adafruit-GFX and I don't know or have not the right know-how yet on how to change ...

Re: 2D graphic lib for ESP-IDF ?

Yesterday night I found some time to port this library and make the Fonts part work in IDF. This is part of my intent to port an existing Epaper espressif32-arduino Firmware into ESP-IDF. You can find it here and unless I'm missing something it can be already added as a git submodule in existing pro...

Re: idf.py is failing when I checkout ESP-IDF v4.1

In that case you shouldnt use esp32s2beta branch, instead use master branch. Thanks chegewara, I will use that one. But that is not the reason idf.py fails. It simply fails checking out branch: release/v4.1 And simply calling idf.py without any arguments I get that error. What I wanted to understan...

idf.py is failing when I checkout ESP-IDF v4.1

Hi there, I'm in Ubuntu Linux, Python version 3.6.9. Today I wanted to compile something in the esp32s2beta since I'm waiting that some S2 arrive, so I switched to: https://github.com/espressif/esp-idf/tree/release/v4.1 update submodules and run pip install requirements again. But I got an error wit...

Re: Help with components visibility

Awesome. Very important part to read that I missed. Thanks for enlightening me. Much appreciated. I will try to build on next weeks a component to drive E-paper displays purely on IDF without using Arduino framework components. Since I tried to refactor GxEPD to work in IDF but is built on a way tha...
