Re: ESP32 as Ethernet/IP (Industrial Protocol) Adapter

It’s not a simple task because ODVA updates the EtherNet/IP standard every year or so. When you run the conformance test, it must comply with the latest version of the standard

If you’re only going to develop a few devices, it’s not worth hiring a team of engineers to read through a specification ...

Can ESP32-P4 support multiple ethernet ports?

I was convinced that the ESP32-P4 only supports one ethernet port and we would have to use an external switch for redundancy

but there's a sentence in the datasheet that caught my eye:
"The Ethernet media access controller includes three RMII interfaces."
in page 70 of ESP32-P4 Series Datasheet v0 ...

Re: What would you like to see in The Next Chip?


Let me toss in another vote for evolution, instead of revolution.

I also think the ESP32S3 is a very good chip in its present form. If there was a way to get an updated version (lets call it S6 for now), I'd like to see three things ­– in the order of importance:
0. More IRAM. Really, that's the ...

Re: ESP8685 Datasheet | 技术规格书

A bit sad it seems not pin to pin compatible with old ESP8285, it would be perfect to change the ESP8285 on some modules we have gaining BLE and more heap without have to redesign everything

Nice release anyway!

Re: Run linux on the ESP32?

There is a curious branch in official linux-xtensa repo, called xtensa-5.6-esp32 with the following description:
Configured with FLASH and PSRAM it is capable of running noMMU Linux

it's here: https://github.com/jcmvbkbc/linux-xtens ... af8a5d20aa

Re: Is it possible to port Advanced Linux Sound Architecture (ALSA) to ESP32 ?

Hi Angus,

Thanks for your post, now it's more clear for me: the intend of sound-open-firmware is to be a firmware that communicates with ALSA and not ALSA itself, so the DSP needs something with Linux connected to work

Before read your post I tried a bit more, probably no one will use this, but ...
