Errors when compiling Esp3DLib and Marlin with esp32-s2

[JoseAntonioMG]

I have designed a 3d printer with Esp32-S2 and have searched for a version of marlin for this purpose, I have found this fork of Marlin:

https://github.com/simon-jouet/Marlin

It works fine, but when incorporating Esp3DLib, compile errors occur, both in version 1.0 and 3.0.

ESP3DLib is not compatible with S2 because it works on different core as Marlin, using a wifi on same core as Marlin will result: when steppers are running to loose steps / hiccups with stepper

Using ESP32 mono core (S2/C3) for your board is bad idea if you want WiFi or BT on your ESP32, but ok if you use it without.

I had discussion with Simon Jouet about that and he agreed - his version was a POC without WiFi

I've managed to compile Simon Jouet's version in Arduino IDE with esp32 core 2.0.0:

Target: Esp32s2 dev module Upload Speed: 921600 USB CDC On Boot: Enabled USB Firmware MSC On Boot: Disabled USB DFU On Boot: Disabled Upload Mode: Internal USB CPU Frequency: 240mhz Flash Frequency: 80mhz Flash Size: 16Mb Partition Schema: Default 4Mb with spiffs (1.22Mb App/1.5Mb SPIFFS) Core debug Level: Verbose PSRAM: Disabled Port: COM24 (Esp32s2 Dev Module)

I don't want to use WiFi, however I don't get a signal on the USB port, nor on the UART port.

My Espressif board is ESP32-S2 Wrover-1 16Mb Flash

I have made some sample sketches to test the development board and they all work:

Wi-Fi WebServer Example Example of USB Serial port output etc etc

Any way how I can compile the source code with a target that allows communication with the board?

I am also interested in buying Esp32-S3, as long as there is a source version of Marlin for this purpose. I have noticed that you have a branch with this specific project, Marlin to compile it in Esp32-S3, is that correct?

[luc-github]

My porting for S3 is lacking the I2S support because I am not familiar with it and need to study it, the S3 I2S API is totally different compare to ESP32 and ESP32-S2

About UART I do not remember any issue during my test but there recent issue raised https://github.com/luc-github/ESP3DLib/issues/65

so there is some compatibility issue for sure

that said on ESP3D I have no issue with basic usage of serial, I did not have dig in yet

[JoseAntonioMG]

I don't use I2S, my development board is simpler and I only use the pins that ESP32 offers. But I would like to know if the source code works on an ESP32-S3, since I would have to redesign my board.

[JoseAntonioMG]

The pinouts of the ESP32-S2 Wrover and the ESP32-S3 Wroom are different, so I have to redesign everything.

[luc-github]

The board I have with S3 MCU use I2S, so I cannot say if imy porting works without I2S as I did not tested fully because i2S is not working

[JoseAntonioMG]

Ok, thank you very much for the information. I will try Esp32S3 and redesign my board. I'll tell you how it worked for me.

Sure - I close issue then Good luck
