Spectacular sprite_tm - thank you so much for posting. We are digesting this as I write this.

Hi Alexey, The LIBUSB errors seem to be a red herring - when I first saw them I searched else where and it seems that Openocd searches for USB devices and tried a few before finding the right one. I downloaded the latest Openocd-esp32 source from Github for Windows under msys and built it - it's a d...

And if it helps, here's an openocd log with extra debugging turned on: bin/openocd -d 3 -s share/openocd/scripts -f interface/ftdi/esp32_devkitj_v1.cfg -f board/esp-wroom-32.cfg 2>&1 | tee openocd.log It certainly seems to me that events are being sent - they just don't seem to be making it into the...

Very happy to have a go at the i2s setup and post the results for assistance, thereby increasing the community knowledge, unless someone is already actively working on this.

kind regards

Thanks guys, I appreciate the suggestions. It does feel like the FreeRTOS clock is getting int the way somehow, although I'm not sure even if we discover this how we change this, or give the timer group priority over the FreeRTOS clock (for example). Our next task is to actually get the i2s module w...

Hi all, We are porting one of our LED panel driver boards to the ESP32, as much to learn about this wonderful chip as anything. We have hit a snag. LED panels are not complex - you disable the display, pump out the lit pixels over a shift register, select which row this should be, then re-enable the...
