Does .NET nanoFramework on ESP32 support generics

I'm attempting to write a C# application with a generic class, targeting ESP32. When launching the debugger, the Visual Studio nanoFramework extension's debug process appears to be stuck in an infinite loop at the "Loading Deployment Assemblies" step.

Here's the output I see in the VS2019 debug window:

I think the problem is that when you check the strings you skip printing all of them even if only one of the three is invalid.

how to plot specific segment from density.lpp

Asked 2020-May-15 at 08:11

I use density.lpp for kernel density estimation. I want to pick specific segment in that and plot the estimation through chosen segment. As an example, I have a road which is a combination of two segments. each segments have different length so I don't know how many pieces each of them are divided by.

here is the locations of vertices and road segment ids. https://www.dropbox.com/s/fmuul0b6lus279c/R.csv?dl=0

here is the code I used to create spatial lines data frame and random points on the network and get density estimation.

Is there a way to know how many pieces each segment divided by? OR if I want to plot locations vs estimation for chosen segment how can I do? Using dimyx=100 created 199 estimation points but I don't know how many of them belongs to Swid=1 or Swid=2.

One approached I used was, using gDistance it works fine in this problem because these segments connected to one directions however, when there is 4 ways connection, some of the lambda values connects to another segments which is not belongs to that segment. I provided picture and circled 2 points, when I used gDistance, those points connected to other segments. Any ideas?

...

ANSWER

Answered 2020-May-15 at 08:11

This is a question about the spatstat package.

The result of density.lpp is an object of class linim. For any such object, you can use as.data.frame to extract the data. This yields a data frame with one row for each sample point on the network. For each sample point, the data are xc, yc (coordinates of nearest pixel centre), x,y (exact coordinates of sample point on network), seg (identifier of segment), tp (relative position along segment) and values (the density value). If you split the data frame by the seg column, you will get the data for invididual segments of the network.

However, it seems that you may want information about the internal workings of density.lpp. In order to achieve adequate accuracy during the computation phase, density.lpp subdivides each network segment into many short segments (using a complex set of rules). This information is lost when the final results are discretised into a linim object and returned. The attribute "dx" reports the length of the short segments that were used in the computation phase, but that's all.

If you email me directly I can show you how to extract the internal information.

QUESTION

CreateWindowW() fails a first time and then works afterwards [C++]

Asked 2020-May-04 at 19:50

So I'm trying to program an application that will help me log something and facilitate my actions in the future.

I wanted to make it as simple as possible, so I decided to use Win32API.

So I've made the necessary and created the windows/styles I needed, etcetera.

But there is something that triggers me a lot:

When I click on a button called "Add attendee," a window shall popup and asks me an attendee's name.

But when I click it a first time, nothing happens. But when I click it a second time, aforementioned window appears naturally.

So as to discover which problem it is, I decided to put the GetLastError() function, but it unfortunately returned 0 whenever I click on the "Add attendee" button a first time(when the window doesn't popup).

To know whether CreateWindowW() is the problem or not, I put std::clog << "Test" << std::endl; at the beginning of the WM_CREATE event. And as expected, the text doesn't show up a first time of clicking but it does a second time.

To know further, I decided to do the following:

Put std::clog << "Test1" << std::endl; before CreateWindowW();
Put std::clog << "Test2" << std::endl; after CreateWindowW();
Put std::clog << "Test3" << std::endl; at the beginning of the WM_CREATE event;
Put std::clog << GetLastError() << std::endl; after std::clog << "Test2" << std::endl;.

Gotten results:

A first time:

"Test1" is successfully written;
"Test2" is successfully written;
"Test3" fails and doesn't show up;
GetLastError() returns 0.

A second time:

"Test1" is successfully written;
"Test2" is successfully written;
"Test3" is successfully written;
GetLastError() returns 0.

After this, I then tried the following:

Put std::clog << "Terminate" << std::endl; at the beginning of the WM_DESTROY and WM_CLOSE events.

And as expected, "Terminate" is not written when I click on the "Add attendee" button a first time, and it does show up a second time when I close the window.

So according to the obtained results, I then deduced that the problem comes from CreateWindowW(). But the real question is why? GetLastError() returns 0, so normally everything shall be fine.

Here are the parts of my code that imply aforesaid results(entire code), have fun:

How does lpp() deal with points that don't fall exactly on a segment?

Asked 2020-Mar-09 at 09:40

If the coordinates of a point do not fall exactly on a line segment in a linnet object, how does lpp() handle that point?

Does it get dropped? Or snapped to the nearest segment?

...

ANSWER

Answered 2020-Mar-09 at 09:40

It is “snapped” (projected) to the nearest segment no matter how far away this is. Thus you should probably prepare your data with some more steps before calling lpp. Below is a simple example which you could try to mimick if all your points are in a ppp called X and the main component of your linnet is called L. Of course you need to adapt distance thresholds etc. but hopefully it helps you in the right direction.

ANSWER

Answered 2020-Feb-14 at 23:05

It will be wrong to simply let y=0 for all your points and then proceed as if you had a point pattern in two dimensions. Your suggestion of using lpp is good. Regarding how to define the linnet and lpp try to look at my answer here.

I have considered making a small package to handle one dimensional patterns more easily in spatstat, but so far I have only started the package with a single function to make the definition of the appropriate lpp easier. If you feel adventurous you can install it from the GitHub repo via the remotes package:
