"Why we need to retire the blinking LED as the entry into embedded programming"

--- Quote ---Compared to this, the classic LED blinking example of the embedded world looks as feeble as a gesture of a man who just woke up from a coma and is told to blink once if he is conscious.

Hands off my blinky!

Now that is well put!

"Compared to this, the classic LED blinking example of the embedded world looks as feeble as a gesture of a man who just woke up from a coma and is told to blink once if he is conscious."

Blinking a LED and waking from a coma. Both represent proof of life.

What rubbish!

"Hello, Cloud" in just 12 lines of Python. Give me a break.


--- Code: ---wifi.link("SSID",wifi.WIFI_WPA2,"password")

--- End code ---

Right. Nothing at all can go wrong there, leaving you scratching your head whether you got the WPA2 password wrong, or the connection to the ESP32 isn't working, or you didn't actually manage to download your code to the board, or ...


--- Code: ---thing = iot.Device("lJilHMrRU39spSMoJATGdeVs","maker:4JQTMUt5kNoqW1VeVoeEuiyKAFik6Nek8pDYkGD",http_client.HttpClient)

--- End code ---

Ho Lee Fuk.

Does he remember that to type into each new program?


We don't use "Hello, World" because it's it's an awesome display of programming prowess -- we use it because it's the simplest thing that can possibly work and prove that our compiler, linker, library etc are in working order and we uttered the right incantations.

Same with blinky, except it's even simpler.

If a mainframe or PC programmer *could* hook a simple LED to a CPU pin somewhere and write blinky as the first program instead of "Hello, World" then they *would*.

And get off my lawn.

SiliconWizard:
Ah ah ah. I admit that was a good one. A good bad one. :-DD

This is the stupidest thing I've heard. But to be expected from people advocating Python on MCUs.
