rshell no micropython boards connected

The raspberry pi uses the latest version of Raspberry Pi OS Lite I have flashed the latest stable version of ESP32 (1.13) ...

size of object

Is there an equivalent of sys.getsizeof() in micropython? I am looking to check the size of various objects prior to sending data across a LPWAN from a remote IOT device. If the size is too large I may split the data or save to a local SD card. If this is not implemented, is there a way I can obtain...

Re: NodeMCU boot loop after fresh install

Not sure, it appears it is the boot that will not work if the dual I/O option is not selected during flash.
Did it work in the end?

Re: NodeMCU boot loop after fresh install

try

Code: Select all

esptool.py --port /dev/ttyUSB0 --baud 460800 write_flash --flash_size=detect -fm dio 0 esp8266-20190125-v1.10.bin
note the additional -fm dio option on esptool
this is mentioned in the getting started tutorial
I just tried this on my Node MCU and it flashed and started fine.

Re: rshell 0.0.17 released

no more defining buffer sizes on the esp8266, just define the port and it just starts!
Great tool Dave,
many, many thanks for starting and maintaining this.

Re: howto: Control passive buzzer

PWM. This tutorial should give you a helping hand if you have an esp board. Esp boards do have a lower frequency limit, if you need higher try the pyboard.

Re: Pyboard D - demo

the specs at 25' on the video may give you an answer

10uA during deepsleep. Try running a pi zero on batteries for a while and see how long you last.

Re: Micropython as Arduino killer

... As for libraries, I think we all know that this is an area Micropython could improve. They tend to be scattered across github and the best option to find what you need is usually to search, then if needed post, in this forum! Perhaps this interest is a trigger to pull together the libraries in ...
