How good is MCU based on RISC-V? (ESP32-C6)

Now we can see MCUs based on RISC-V all around us.
Several companies have now started producing and selling development boards and CHIPs based on RISC-V.
I'm trying to find out the good points of RISC-V by comparing the ESP32-C6 and ESP32-S3 released by Espressif this time.
Could RISC-V be the only fighter capable of fighting ARM? Currently, it's lacking in many aspects, but if RISC-V-based applications expand, there will be opportunities.

I think that is prounced as RISC-Five,😀

[@mysticmarble94]

Yes

[@ThatProject]

My mistake 😭

[@HadrienDorfman]

@@ThatProject don't bother, your video was mint :)

[@adamkoxxl]

There is going to be ESP32-C5 which is similar to C6 but will also have a 5GHz WiFi.

[@astrolemonade349]

where did you find that information? afaik there is no C5 yet.

[@matthewbass8152]

Great video dude!!!

[@hightechjoe1]

Maybe next time, can you measure power consumption with WIFI off or in sleep mode? Thank you for sharing your projects. I'm going to try your VNC client with Klipperscreen.

Nice video!
Xtensa is VLIW not RISC. That means it'll excel at some jobs (DSP, matrix operations, etc.... heck Xtensa is designed as a DSP core) but be effectively the same as a single issue in order core like the C3 on other tasks. But at lower code density.

Hi. A project with a thermal camera would be cool… e.g connect it to a drone and detect things. And compare with a infrared camera. Make it low weight and operate it 30 min woth a battery…

[@electrovoltmce]

It is possible to turn an ESP32 C6 into a WIFI DAC Adio - as a reference to play music from UA-cam and with the help of C6 to connect it to an amplifier.

[@ThatProject]

I don't know much about Wireless DAC Audio. I think I need more study on this. Sorry for not being helpful.

[@MikePreston-darkflib]

Xtensa have said the C6 code is not power optimised yet, so expect results to improve.

[@ThatProject]

Thanks for sharing. Is there an official page that mentions this?

[@MikePreston-darkflib]

I seem to recall it being a forum response about the latest esp-idf or esp32-arduino releases, but I can't seem yo find it right now.
But the gist is that right now they are mostly optimising for support and bugs, the power optimization is not as high priority right now.

[@ThatProject]

@@MikePreston-darkflib All right. Thank you for the information. I haven't found any good project ideas using C6 yet. If you have one, please share it. Thank you.

[@MikePreston-darkflib]

@@ThatProject The two things that jump out at me for the C6 over other ESP models is that it supports zigbee (so can interop with other home automation devices) and 802.11ax which in theory gives the ability to be very low power while still remaining connected to wifi and waking up at fixed intervals to see if there is any data for it.
Both these are big advances and open up some applications that weren't possible before.
The other thing that is likely less important to most other people is that it has better security than some of the older models - both in terms of ciphers etc and in terms of protecting code and data during early boot.
There is also talk of a variant on the C6 which will work on 5GHz, which while I have not seen any announcement yet of, is rumoured to be launching in the next 6 months or so.

[@ThatProject]

@@MikePreston-darkflib If it supports 5Ghz, I'm planning to do some testing on projects that require fast data transmission. ZigBee modules can also transmit and receive data at low power, but there are no good ideas yet for any special projects using them.

[@yes_man_lol]

Can we use micro python on s3 and c6 too?

[@ThatProject]

As far as I know, ESP32-C6 is not supported by anything right now, including, Arduino IDE, Circuit Python. Need more time to do using them.

[@collinb5524]

RISC-5

[@ThatProject]

My bad. 😭

[@dunk_law]

It is NOT single core. It has an LP core.

[@ThatProject]

It's Ultra-low-power SoC with RISC-V single-core microprocessor.
