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

So I'm looking forward someone with enough C++ and driver knowledge to help on this libraries. I don't have sadly the right amount of money to invest, but the coder that wants to take the post, will get paid for his hours research time and also get the Epaper display tools for free that he / she can...

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...
