Espressif is on fire! And the CPU even has SIMD instructions! RISC-V cores is a big deal for embedded systems because now compiling for SoCs is only a matter of `rustup target add riscv32imac-unknown-none-elf` instead of downloading half-broken proprietary toolchains and SDKs. Take a look at https://kerkour.com/introduction-to-embedded-development-wit... and https://kerkour.com/rust-esp32-pentest to get started with…

very interesting, do you have a pointer with more info on what kind of SIMD support it has?

Why on earth SIMD instead of the risc-v vector extensions that are supposed to be better?

I've been building hobby LED art projects with WLED (exclusively built on the ESP32 platform). It's been a blast. These little boards are so powerful and the open source community continues to amaze me. My preferred controller platform is of the QuinLED line - comes with power distribution, voltage regulators, fat copper lines, configurable data-line resistors, and smart auxiliary hardware support all for an affordab…

I do a lot of LED projects too but I just use ws2812s. What do you need the controller for? Large brightness perhaps? Just curious.

I wish Espressif was an American company and publicly traded. I'd invest heavily. I have nothing but good things to say about their products. Their product naming could be better; S3 is going to show S31 in the search results.

if it were American it probably would have been hostile-takeovered by Qualcomm or someone else and tightened down long ago.

Any reason why this device wouldn't have Z-Wave? Is the wireless protocol significantly different than Thread and Zigbee?

Z-Wave is completely different from Zigbee. Different frequency bands, modulation, etc.

And there are still just two suppliers of Z-Wave radios, as far as I know. I haven't bothered to re-check recently. Up until ~2022 there was just _one_ supplier, you could open any Z-Wave device and find exactly the same chip. Sometimes on a cute little daughter board.

WLED is a system that runs on the ESP32 for some cool capabilities to drive the ws2812s, OP linked above.

Good to have WiFi and wired ethernet on the same part again. Although we lost the MIPI support that the P4 dual-core RISC-V line has.

Dang would love to have both in the same chip.

I kind of wish these all weren't called ESP32. ESP8266 and ESP8285 -> ESP32 made sense, but now we have 10+ different versions with different features and different architectures. Kind of like how in every thread involving a Raspberry Pi Pico (RP2030/RP2350), there's always someone confusing it with the single board computer version. The ESP32 (Classic, usually WROOM-32E) is still usually what comes to mind when I he…

But it's the same scheme as STM32, EFM32, GD32, …

Yes and those schemes are just as bad as Espressif's

Is anyone else worried that these chips are all made in China?

I am concerned by all chips and software made by giant corporations. None of them are trustable, and any one of them will sell me out for a buck.

We must constantly fight to have open source and audited chips and software made in commodity fashion.

cr.yp.to/ is also a pretty cool URL, and has been around for a looong time

Earlier quoted context omitted.

It signals ESP-IDF compatibility

They can signal that with numbers other than 32, the "ESP" part is what matters.

ESP-IDF is only compatible with the ESP32 range of devices, not all ESP-prefixed devices, so "ESP" alone is not sufficient information to satisfy the earlier comment.
