I agree, but arduino is more fit for real time systems, linux with a vast number of application. For a reason of security too... hacking linux is easier than hacking arduino .. so you can store some information on the arduino chip like a "signature protocol".

The new ESP-P4 will be a interesting one i dunno if it already has a MMU. Hmm having a ARM + Riscv is pretty weird would have to have multiple linux’es as i guess it can’t schedule on multi arch.

Going to have to check this out! I need Internet connectivity and things like FTP log file uploading for my systems but don't want to loose the ease of use of Arduino coding, although anything like FTP causes Arduino to fall on its face

A good example. Internet and video are not fun for an Arduino. Linux is easier for these topics.

One thing that would be very useful would be to have the status of pin declared as outputs visible from both systems avoiding using 4 pins to communicate. (never understood why in Arduino you can't read the state of an output without bothering registers) In any case I already have at least 37 projects in mind to use a Milk-V DUO S. First: a glorious keyboard IBM M Series USB/Wifi/Ethernet with macros and the possibility of reprogramming. (Already partially done with Arduino Due ....but i need more CPU)

@andreasSpiess, do you have any idea why the newest version (1.1.0) doesn't support Arduino? Would that suggestion that support for Arduino will be going away?

The Teensy 4 has been running Arduino on a 600 MHz dual-issue Cortex-M7 (close to the same speed as this single-issue 1.0 GHz CPU) since mid 2019 -- and with a heatsink you can safely overclock it to 960 MHz (it's right in the Arduino IDE settings for it). But it's only got 1 MB RAM and no MMU. And at $20+ it was a great deal in 2019 but now is far more expensive than the Duo.

At least the new sounds make for lots of comments and engagement;) But yeah, I see you're already well aware this was not a new favourite:D

I remember RPi-like boards with additional Cortex M4 core. I still have one somewhere. They didn't take off. Too different areas of use.

What would really be an interesting topic here is how to effectively communicate between the two cores. I doubt that doing this via hardware I2C is a good solution, especially if it requires actual hardware connections.

@AndreasSpiess

I agree that an internal communication would be better. Maybe we just did not yet get an example, or it is not forseen in HW...

The MilkV Duo might have face detection (?). Did you try pointing the camera at yourself? I have both the Duo and the Duo S but only have a camera for the Duo S and that test program you ran detects faces - puts a rectangle around my face. The Duo S has something called a "TPU" for this purpose. Hard to tell from the documentation if the smaller Duo can also do this.

@AndreasSpiess

28 күн бұрын

I only used the face detection example and it worked. It seems it does not use the TPU, though. There are other examples using TPU also for the DUO.

I bought years ago a Udoo Neo board which has an iMX cpu running Linux and a core running Arduino code. It wasn't based on RISC-V architecture though

Looks like some serious potential in these boards. Can they output HDMI or VGA? This is my challenge these days. While the zero w (2) is now available, the $15 price (+ship) is a turnoff, and then its another $9 for a mini-hdmi to full hdmi cable.

This is really interesting to me, I often have need for both the realtime IO of a microcontroller and the network stack and data handling of a real OS, but making an arduino and a raspberry pi speak to each other is tiresome. If they were both on the same chip, though...

So far, I also only saw them communicating via pins. But maybe they just did not implement this functionality in software.

12:13 is this really an 24 Ghz radar sensor or an resonant circuit that toggles around somewhere between 3 and 4 Ghz outside any official bands?

Nice presentation. About the last part, you quickly presented a radar solution. Well I am seeking a solution to monitor and record incoming traffic speed at the street in front of the house. My wifi extend up to the street limits. If you ever find a solution could you make a complete presentation. You made a radar presentation on a previous date, but vehicle speed could not be evaluated because a PC is required to crunch the number. However this board present new possibilities that could make insitu speed detection without the use of a pc?

I would distinguish between speed measurements and data transmission. You get devices for measuring traffic speed. Maybe you find one with a data connector where you can connect a data link to your home using WiFi or any other wireless protocol.
