> when its vehicles are driven remotely? They aren't. The car asks the remote operator about its options, the operator suggests an option, the car proceeds. Nobody is driving in realtime over LTE, that would be insane.

Not really, those are using PIR motion sensors to wake up, so you'd need to be able to capture the burst of activity when the camera actually wakes up and takes a picture. PIR circuit is very low power, so not much RF energy to detect

It's a Cortex-M33, a 32bit microcontroller core with no virtual memory. Are we really comparing microcontrollers to modern aarch64 processors?

While we’re at it, let’s also ban cars because terrorists can use them to carry bombs, just like they could use drones. Drones are not the problem here, the bombs are. And in States, any lunatic can buy an assault rifle and shoot up a schoo

People can be much more annoying than drones, yet they are legal.. But if you want to embrace your inner Karen, get a Remote ID scanner app for your phone - it shows operator position so you can go confront the person flying..

At least microUSB always works, with Chinese USB-C boards they skimp on the CC pull-ups so the ports don't work with typeC to typeC cables.

Yeah that's just the TASS version, so likely to be a fake to cover a manufacturing defect.

On the other hand, knowing how the detection works you could shield the camera and suspend operations when significant luminance changes are detected. Cat and mouse, as usual :)

Battle bots are not exactly robotics, they’re RC cars with extra servo channels. Personally I find them boring compared to FPV, but the entry is pretty much the same - watch YouTube tutorials. You could find a book but anything you’d find t

Proper logging for retention would surely involve a point where you encrypt the data with a temporary key and then encrypt that key with the public key and only your top brass would have access to the HSM that could decrypt that blob..

I don’t see how your 32bit float argument applies to codec specs, since you can only get a 24bit signed int from/to a codec. You’ll need a limiter to convert floats to ints either way, 24bit or not.

Yocto works the same way whether it’s Pi or iMX, most of the learning curve has nothing to do with the SoC. So it’s really strange to hear that your Pi workflow is better than anything you’d get with another chip..

Many, many cheap MCUs have peripherals that can decode quadrature in hardware. E.g, PCNT on ESP32, timer modes on STM32 etc. Might as well use PIO to implement I2C or UART :)

Personally I would use a timer capture channel for input, that way you get automatic timestamp capture and you don't depend on gpio isr handlers firing on time in case there's some other concurrent interrupt.
