It is espressif internal issues tracking number, just like on github they have IDFGH-xxx.

Strange is that espressif claim this feature support already has been added in February comment

Thank you. I've seen the P4 version but there is no documentation available on the Espressif site AFAIK, and I don't even know if it is produced at the moment. With 55 GPIO it could be a real monster but I've to develop my project in months, not years, in order to show a prototype ASAP to the publi...

Yes, it should be possible with composite USB device, and without hardware DTR/RTS. As far as i remember espressif arduino team implemented this some time ago. Espressif is using "special pattern" to switch esp32 into download mode. Its some mix of software DTR/RTS and uart speed set to 1200bps. Whe...

If i understand correctly you may make us of parallel IO on H2, C5, C6 or P4

P4 is most powerful and can handle up to 16+2 lines.

Not implemented yet

I know this does not answer your question, but i hope this may help you a bit. You asked about C3 chip, but new chips H2, C5 and C6 have new peripheral, which is parallel IO. https://docs.espressif.com/projects/esp-idf/en/stable/esp32c6/api-reference/peripherals/parlio.html https://github.com/espres...

https://developerhelp.microchip.com/xwiki/bin/view/applications/usb/speeds-specs/full-speed/ In theory CDC ACM should reach transfer around 1MB/s, not sure if esp32 can reach such transfer speed, but it only theory. To get highest throughput you have to make sure that: - esp32 is sending data in tig...

https://community.st.com/t5/mems-sensors/inprove-the-speed-of-the-mass-storage-as-u-disk/td-p/523996 Now you have to add flash read/write operations time, which is another overhead. Couple years ago I performed USB MSC tests on S3, you can find results somewhere on the forum. As far as I remember th...

This is only is confirming what i said. There is a bug in extension. When you do fullclean then managed components will be removed and you will end up with code which has includes and cmake complaining about it, which is wrong. Also you may have and in many cases you will have Kconfig file to config...

It suppose to works with buttons from extension. I personally prefer to use CLI instead of extension. Extension is another layer of software, which has a bugs (there is no software w/o bugs), so it may cause more problems one way or another. I am just saying that you have to start build, from cli or...
