ImportError when importing modules that exist in micropython

Asked 2021-Dec-05 at 17:39

I am currently working on a project which involves taking soil moisture measurements using sensors and a Pycom LoPy4 mounted on the expansion board V3.1. I am currently using VS code as my IDE and using the pymakr extension to run the micropython with my board.

At the start of my project the import function was working correctly and I was using code directly copied from the internet as seen below and it would run without error:

You can add the directory to the sys.path that python uses to find modules and import as usual:

QUESTION

Node Red: Temperature Alarm if measured value is at multiple times different to set value

Asked 2021-Jun-02 at 23:58

I'm using Node Red to monitor a set of aquaria. We have 14x DS18b20 sensors, one for each aquarium. I'm able to send an alarm via email if the measured temperature of one sensor is different to the set value. However, sometimes, during maintenance, we take the sensors out of the aquaria. Therefore, I'd like to write a fucntion that only sets the alarm if the abnormal value was mesured e.g. three consecutive times (values are measured every 15 min). How could I do that?
Currently, I wrote a function that sets msg.payload to "Alarm" if any msg.payload[i].temp (the 14 measured values in an array) is more than 1.5 °C diffrent to the set value. This fucntion is followed by a switch that then triggers an email.
Do you have suggestions for my problem? Thanks for your help!

You could try using global context to save a counter of successive abnormal measures. For example, on a function node named "Evalute global abnormal measure"

Nanoframework ESP32 OneWire Pin

Asked 2021-Jan-29 at 19:27

is the one wire bus for ESP32 only available for pin 16 and 17? I am going to rework a project which was first written in Arduino IDE. There it was possible to set the pin for the one wire bus. I want to use nanoframework but my pcb is already there and port 15 and 23 are used for the one wire bus. I really like nanoframework and the sample for DS18B20 does not find any sensor. With Arduino IDE it is working. Is there a way to specifiy the pin for one wire? THX

ANSWER

Answered 2021-Jan-29 at 19:27

.NET nanoFramework implements support for 1-Wire protocol using UART, therefore it requires both TX and RX UART pins to work. On the pre-build firmware images it's configured to use pins 16 and 17 as you've mentioned.

You have to connect those together and also add a 4.7k pull up resistor.

ANSWER

The problem is using a default namespace without giving it a name to use in queries.

From the XML::LibXML::Node documentation for findnodes:

A common mistake about XPath is to assume that node tests consisting of an element name with no prefix match elements in the default namespace. This assumption is wrong - by XPath specification, such node tests can only match elements that are in no (i.e. null) namespace.

Namespaces, especially a default one, and XPath just don't play nicely without some work.

Using XML::LibXML::XPathContext and assigning a name to the namespace is one of the suggested approaches. Like so:

C# is not the same as javascript, so you cannot just copy and paste javascript code.

Javascript has one number type for all purposes (which corresponds to C# double type). So when you do this in javascipt:
