Re: A power meter - using the Pyboard as a measuring instrument

The toroidal transformer is rated at 6VA - it was the smallest stocked at my usual supplier (CPC/Farnell). It fitted in the box so I used it. A smaller one would undoubtedly suffice if you can find one. As for hand tools I was trained in metalwork where we were required to produce work in mild stee...

Re: urequests.post failures

First posts do not allow bbcode as some spammers used it to send pictures not only of naked PCBs but of other naked things....
As we need to approve the first posts and they always open up full for approval, we had an office-rules violation from time to time ;)
Now it should work for you

Re: Fail to forward REPL to LCD160CR

Hi and welcome, writing to an LCD display is not as easy as you tried. In fact what you did was to write ASCII to the UART port. However, even if the display is connected to the UART port it is usually not 'smart' on its own, how should it know what to do with the information you send? What is text ...

Re: keras neaural network - mycropython

In that case go for a RPi instead of a micropython board. A Pi-Zero if it has to be small....

Re: es8266 (itead sonoff) hanged after flashing

Hey Peter, sorry for being quit on this for a longer period. Nice to hear you had more success with the new modules. I will go an order some to compare your findings. Would be really nice to see what is the exact difference between the different generations. We might be able to ask the vendor. Somet...

Re: es8266 (itead sonoff) hanged after flashing

To add to this miracle: Other projects seem to happily use the sonoff units. I searched but could not find any similar issues or threads for that matter. E.h. espeasy seems to supports them. However, the sonoff units had several hardware releases. I believe I still use an early version and I know Pe...

Re: es8266 (itead sonoff) hanged after flashing

Hi, as Peter mentioned, we invested a lot of time into these units (Peter much more then me). My last investigation was about the ping times, since Peter mentioned considerable long reply times. On my unit, which worked without issues, running the unit on REPL (thus, it was not occupied with any CPU...

Re: How to have micro python interpreter running on a very simple function

Hi and welcome, I am not sure what you are trying to do. If you simply want to execute the python code, there is no need for tweaking and compiling. Simply install the latest firmware for your board and copy your python function in a file 'main.py'. The python interpreter on the board will call main...

Re: HSPI chip select

Hi, maybe you find more answers looking for the Esp8266 instead of the ESP2866 ;) But yes, as far as I can tell (never used SPI with micropython) CS is not implemented by the generic SPI driver. However, as it is a simple io action, one can simply create a Pin instance to do the job and wrap this in...

Differences between Micropython ports for ESP32 and ESP8266

Hi, as many questions move around with the meta topic, "Can I do / I can't do something on the ESP32, I used to do on the ESP8266", I thought it would be a good idea to collect user experiences and observations. This info can go back then as feature requests, bug reports or into an official part of ...
