If you have working benchmarking code you want tested, I can do the test. I have wrover modules with ESP32 V3 chip, and S3 beta 3 modules.

Re: ESP32-S3 (Beta2) MARLIN_9_1B on ESP32-S3-Addax-1 V1.0 Specs & Datasheet
IMPORTANT!: If you update IDF master branch to the latest version, the Addax V1.0 boards that has the ESP32-S3(beta 3) chips are no longer supported. Commits have been made at the beggining of June. Latest branch that seems to supports older S3: https://github.com/espressif/esp-idf/tree/3b60c2e131bc...

Re: ESP32-S3 (Beta2) MARLIN_9_1B on ESP32-S3-Addax-1 V1.0 Specs & Datasheet
That's interesting to know. I never really played with asm on vanilla since there was no official docs. Any info on what type of vector instructions on esp32-s3? Perhaps a technical reference manual running around? AFAIK, the S3 in therms of CPU architecture is exactly the same as the vanilla ESP32...

Re: ESP32-S3 (Beta2) MARLIN_9_1B on ESP32-S3-Addax-1 V1.0 Specs & Datasheet
Esp32 - S3 supports register windowing!! That has potential for substantial performance gains. Just curious if GCC supports it? edit: It seems it does https://gcc.gnu.org/onlinedocs/gcc/Xtensa-Options.html :) The Xtensa core used in the vanilla ESP32 already supports windowing, I don't remember how...

ESP32 ICM426XX driver
Hi Guys, I have ported the InvenSense's official driver to the ESP-IDF platform, for ICM426XX 6-axis motion sensors. The port is not 100% yet, as there is a pre-built lib that needs to be integrated, but other than that, it works nicely. https://github.com/VaderMester/ESP32-ICM426XX-driver I made it...

Re: OTA hangs when using I2C
Gotcha. Well, FWIW I copied the OTA source into my project, and just inserted a few lines. I may have to roll with that and be happy. It's just odd this problem hasn't surfaced before and gotten a proper fix. If I knew more about callbacks, I would be tempted to add a callback to the OTA library, a...

Re: OTA hangs when using I2C
That's the problem, I'm using a library. So what you are telling me is that I need to use my own OTA routine. I was hoping for a holistic solution other people could also use with AsyncElegantOTA. Maybe you are not required to modify the library. First you must create a FreeRTOS task that calls Asy...

Re: I2C reading problem - PCF85063A
Thanks for the reply. Yes, 12K resistors are present on both SDA and SCL lines. I however tried enabling/disabling internal pull-ups resistors without any visible effect. I've removed the error checking lines in the sample test I've enclosed, both i2c_master_cmd_begin calls return OK (0). I'll try ...

Re: Looking for programmer to port code to ESP32 for me
So, are you available? The code I want to port is the "Decawave" api. A simpler approach might be to get the C++ source code used in arduino into ESP-IDF. All the code is available in cpp and h file but not sure how to get this working/included into my esp-idf project. If you are still looking I se...
