Why didn't they pack more ram on this? 400K is a bit tight, we often hit the ceiling with the ESP32's 512K of internal RAM. Does anyone know if they support SPI-connected external RAM on this? It has been a lifesaver on the ESP32, especially since WROVER-E fixed most of the long standing bugs that were plaguing the earlier revisions. It is slow as hell, but having 4MB (+4MB high memory) of connected RAM on a microcon…

From my MS-DOS/Speccy programming days 400KB is a lot, no need to make use of the OS, if one can avoid it.

lol. yes. i was going to recommend writing a 6502 or Z80 emulator and then write the application in Tiny Basic or FORTH.

Super great to see new designs with RISC-V keeping up with tech, the BL602 and ESP32-C3 are currently available though, and I've been working with the Pinenut for a side project. I hope more RPi-like BL702 boards become more widely available for RISC-V too.

I got some esp32-c3 engineering sample devkits.

I'm wondering if there's any point at all in Espressif going to production with these chips- going from wifi4 to wifi6 seems to be the main change, and it should make a huge difference for how well behaved a network citizen the chip is.

like you I was elated to see some iot wifi hardware with modern connectivity standards. fantastic to see iot not have to lag by multiple years. very important upgrades, having ofdma, allowing multiple devices to share the ap.

I really wish Thread mesh networking would become standard on new Wi-Fi routers. Google Nest has hardware support for it, but not sure if it's enabled yet. I think Thread is a much better fit for IP connectivity for IoT devices. Nordic Semiconductor nRF SoCs can do Bluetooth LE and Thread on the same radio at the same time, so should be very cost effective. I'd gladly replace all my Zigbee devices with Thread ones if…

Is Thread still happening? Last time I checked the only hub available was Nest, although Apple hardware has support but it's not enabled in software. Other than a couple of niche home automation products, nothing supports it. When will I be able to buy smart light bulbs for $10 that use Thread?

Thread is one of the initially supported wireless layers (alongside wifi) for https://github.com/project-chip/connectedhomeip

Not mentioned in the title: It's a 160mhz RISC-V chip

Kind of interesting that the only thing in the part number that denotes that is the "C6" part. Apparently "C3" is another ESP32 with a RISC-V cpu. I'd have gone with "ESPR" since it fits "EspressIf" but denotes RISC-V clearly.

When I played around with ESP32 when it just came out, the problem was that the toolchains and software just weren't done yet. There were a lot of features that existed on hardware, but without toolchain support, docs, or sample code it was close to impossible to use them. I'm not sure how it works now, but especially for newer stuff I wouldn't rely on the fact that the hardware claims to support something -- if the…

I'm not familiar with other microcontrollers, but ESP-IDF seems to be very actively developed. I bought a wESP32 a few months ago and initially couldn't figure out how to enable ethernet... came back after some ESP-IDF updates and had it working in 10 minutes. But you are probably correct about the latest chips.

ESP-IDF is super friendly, I was amazed how easy it was to get it set up and configured compared to my experience with some other embedded toolchains I've used before.

Well unlike the Atmel chips, it is -- like it's predecessor the ESP8266 -- a totally internet focused MCU. So with TLS and HTTP requests, and receiving streams and WebSockets and whatever else, it's not hard to imagine what to do with it. More is better. For example I have one ESP32 setup with 8 megs of PSRAM that does a full scan of a currency exchange every 15 seconds. Loads all the data into RAM, which I can subse…

>For example I have one ESP32 setup with 8 megs of PSRAM that does a full scan of a currency exchange every 15 seconds. May I ask why you're doing that on a ESP? Very cool...just surprised at the choice.

Well I wanted to have the exchange info on my watch, which is the simplest answer. :P

(I get no money if you click that btw -- it's just for reference)

The watch has some "trading features" even. If I see an interesting trade I can let it take the trade and finish it to "take profit", while I go and do something else. It has a touch UI and a 240x240 16bit colour screen -- so lots of possibilities there.

Why use the OS then? Just do bare metal runtime like we used to do on MS-DOS days.

What about botnet operators? This would give them a hard time if they have to hack each device specifically instead of recycling old linux vulnerabilities wholesale. The whole IoT industry is strongly committed to make devices available to botnet operators, indeed this looks like the main function, the function on the packaging usually works poorly and is likely just there to convince punters to install the botnet re…

The ESP-IDF environment is based off of FreeRTOS, not Linux. It's essentially a threading library, not so much an OS.

ESP-NOW might be suitable, as it requires less power than regular wifi. From the docs: “ESP-NOW is a kind of connectionless Wi-Fi communication protocol that is defined by Espressif. In ESP-NOW, application data is encapsulated in a vendor-specific action frame and then transmitted from one Wi-Fi device to another without connection.” https://docs.espressif.com/projects/esp-idf/en/latest/esp32/...

Sounds like a security nightmare.

What makes you say that?
