Re: checking a value across lots of Constants
Thanks for responding @Spotlightkid I had hoped to try and keep the config file independent of the functions and also wanted to avoid repeating the Constants within a list or dict. However, perhaps I can't ! so I will progress with your approach and create a dict with keys corresponding with the Con...

checking a value across lots of Constants
I am trying to solve a problem, which probably has a very simple answer. The use case is a set of remote microcontrollers sending data to a central 'broker' microcontroller using the excellent ESP-Now module written by @Glenn20. Each remote microcontroller and the broker contain a config file contai...

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
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.
Code: Select all
esptool.py --port /dev/ttyUSB0 --baud 460800 write_flash --flash_size=detect -fm dio 0 esp8266-20190125-v1.10.bin

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.
