Great comparison - this deserves a lot of views!

The C++ statement

float result = (1234.56 * 7890.12) / 345.67;

is not a good benchmark: the right hand side being constant, it is evaluated at compile-time. You end up with just an assignment of a constant to be done at run time.

Wait, no, not event that! As the variable `result` is not used anywhere in the sketch, it gets optimized-out by the compiler. So the whole “calculation” benchmark gets optimized into this:

while (millis() < endTime) {
calculations++;
}

I don't know whether the Python interpreter can do this kind of optimizations, but the C++ compiler can absolutely not miss them.

I have been waiting for this type of comparison. Thanx Kevin! I have done initial selections between C and Python several times. My main arguments have been: Files, sound or strings -> Python. Complex logic, multiple interfaces -> C. Hardware testing -> Python. The application is to be maintained by a person with limited programming skills -> Python. For the Python implementations I still need to choose between CircuitPython and MicroPython.

24:33 You don't need to click the Verify button, unless you don't intend to upload it afterwards. Just click the Upload button. It then does the same thing, but without compiling it twice.

I agree it compiles when there's no need to though, e.g. after failing to upload because of forgetting to set the port correctly. There's no Stop button either. Despite what I've read, the only reliable way to stop it compiling, when I know I've made a mistake, is to exit the IDE, which doesn't help much because it takes a while to start up again.

Which programming language did you use for your smackdown scores ?

After comparing File systems the score was 7/5 then one comparison later after Development Workflow the score was 7/8

Something fishy is going on here

Thank you for sharing this knowledge. I am currently trying to learn viper and asm_thumb but there is little to no documentation to support this important part of MicroPython. Therefore, please make a series similar to how Life with David did for PIO.

Also, I noticed at 44:20 of your video that MicroPython performed 65536 calculations per second. This number, 65536 is the same as 0xFFFF. When I see an exact number like 65536, this makes me suspicious there is an anomaly with the test that needs further investigation to understand if there is something that is artificially biasing the results.

pico is my favorite microcontroller (running MicroPython)

Can we work with an RTOS using microPython?

[TooSlowTube]

This is the first I've heard that there's an official Arduino IDE for MicroPython. Does it do CircuitPython too? Is there a legitimate reason for CircuitPython to exist, or should Adafruit have just contributed board support packages for MicroPython instead?

TLDR: micropython is easier than C++, especially for noobs. C/C++ a lot faster and more powerful.
