Re: Multithreading-like ideas?

My timer code was behaving in strange ways until I rewrote it to be "restricted".

I would like very much to have documentation about this.

Native code generation, "esp.set_native_code_location()" and how to find spare space in the flash

According to https://docs.micropython.org/en/latest/esp8266/library/esp.html#esp.set_native_code_location , I can generate native code to the flash. Choosing a block in the first megabyte of flash allows native execution without the limits of the <800 bytes default size in IRAM in my system. Less th...

Thanks!.

Multithreading-like ideas?

I need to read data from the ADC as fast as possible (currently about 2.5K samples per second), do a small calculation with the data read and post it somewhere via HTTP or MQTT. The posting is not time critical and I can accumulate several readings per publication. As far as I know, Micropython does...
