Just checking that we are talkign about this ciruit that everyone uses ??

The only thing that I can think of is that the ESP32 doesn't check the condition of GPIO0 as soon as it starts up but rather waits a very short time then checks this way this circuit could work as this circuit set reset/EN high then after that it sets GOPIO0 low.

@Roberthh I have asked everywhere how this auto boot circuit works and never get a response. It seems no one is sure how it works and it was just opied from the espressif development kit and people just use it as it seems to work. My understanding is this: When the ESP32 chip starts up it checks the...

Thank you very much pythoncoder for the links :) Very interesting read and very clever by the Micro-Python designers. So am I right in understanding that normal byte-code emitters is just designed to optimize Ram usage due to the constrained environment that Micro-Python usually runs in and Native e...

I have googled for images of Micro Python and only get the orange snake sitting on the chip. Does anyone have a link to the official grey 1 as I have never seen it.

I thoigh the orange snake sitting on the chip was the logo see https://en.wikipedia.org/wiki/MicroPython

@RobertHH Thanks for your answer. The docs on native and viper emitters is very short and I am not going to be able to teach myself from them. Is there any blogs/tutorials you can suggest for me to study. I am a fast learner, only started to learn programming with my sons Lego mindstorm about 1.5yrs...

Holy shit batman viper code is about 10-20 timer faster than standard Python code I still don't understand if this is possible why is it not the standard rather than only used when specified by the decorator?? What's the downside?? Not supported on ESP32. Is this because the ESP32 isn't capable or i...

Ok this is all new to me, I hadn't heard of native or viper emitters. I am trying to get my head around exactly what they do and how they work. Am I right in thinking the tell the compiler to compile the code different that makes it run faster?? If so why don't we only compile in this faster way?? W...

I add this to my boot.py import gc from sys import modules def reload(mod): mod_name = mod.__name__ del sys.modules[mod_name] gc.collect() return __import__(mod_name) First time that I want to run a file I will use import file_name then anytime after that I want to run it I use reload(file_name)
