ESP32-S3 build with error.

[lanistor]

IDF: release 4.4 PC: MacOS 12.4 Target: ESP32-S3

Do i need some other configuration?

Build end with lots of errors:

Ah there is one detail: EPDiy component won't work with S3 Please add in the very beginning: return()

Line in the component/epdiy/CMakeFiles and also exclude epdiy from the

component/CalEPD/CMakeFiles In the require section but also: Any classes that use epdiy like Epdparallel.

I know is a bit cumbersome but it will take some long months if epdiy ever supports S3 since I2S in LCD mode was replaced by another peripheral called LCD/Camera. If you find a way to exclude this automatically when the MCU is S3 please make a pull request and show me how to do it.

Please also make sure to leave only one demo SRC. This CMakeFile is just a demo the ideal way to implement this would be to add CalEPD as a submodule and Adafruit GFX so you create your own CMakeFile only with the things you need.

@martinberlin So CalEPD can drive parallel epaper without Epdiy?

[martinberlin]

No! Only with EPDiy. So if you are looking for parallel is only EPDiy. I never went so deep in this I2S thing yet (But I'm an epdiy collaborator)

[lanistor]

Thanks a lot, we will try on this.

[martinberlin]

By the way if you would like to drive 8 or 16 datalines parallel both Waveshare and Goodisplay have a solution with IT8951. And for that you can use Lovyan GFX, there are examples here on this repository: https://github.com/martinberlin/cale-idf/tree/feature/45-it8951 Video demo

About S3 please remember to adapt the host: https://github.com/martinberlin/cale-idf/blob/feature/45-it8951/components/CalEPD/epdspi.cpp

For S3 you should also use: SPI2_HOST

[lanistor]

Thanks for the suggestion。

[martinberlin]

Any news here @lanistor ? Did you succeed building this with S3?

[lanistor]

Still trying, on the verge of giving up😂

[martinberlin]

Strange. But did you follow my instructions so EPDiy component is not being compiled anymore? If so, what is the next blocker?

[martinberlin]

Closing here at the end of July since there is no more feedback since 2 weeks @lanistor Please keep the issue alive if you need support.

[martinberlin]

Updated CalEPD to support S3. Pull and give it a new try

[lanistor]

CalEPD can drive parallel epaper with S3 now?

[martinberlin]

No. Only EPDiy can but no S2 or S3 just ESP32 WRover with special PCB
