kandi X-RAY | circle Summary

circle is a C library typically used in Internet of Things (IoT), Raspberry Pi applications. circle has no bugs, it has no vulnerabilities, it has a Strong Copyleft License and it has medium support. You can download it from GitHub.

Circle is a C bare metal programming environment for the Raspberry Pi. It should be usable on all existing models (tested on model A+, B, B+, on Raspberry Pi 2, 3, 4, 400 and on Raspberry Pi Zero), except on the Raspberry Pi Pico, which is not supported. Circle provides several ready-tested [C classes] doc/classes.txt) and [add-on libraries] addon/README), which can be used to control different hardware features of the Raspberry Pi. Together with Circle there are delivered several [sample programs] sample/README), which demonstrate the use of its classes. Circle can be used to create 32-bit or 64-bit bare metal applications. Circle includes bigger (optional) third-party C-libraries for specific purposes in addon/ now. This is the reason why GitHub rates the project as a C-language-project. The main Circle libraries are written in C using classes instead. That’s why it is called a C programming environment.

            Whenever actionmodal is open you can save the index() of div which has open that modal inside data-attribute . Then , when appendaction button is clicked get the data-attribute and then use $(".steplist .input-group:eq(" + row_no + ")").. to add new data inside your input-group div.

            how to append different id into div and add text into input value when trigger click event
            Asked 2021-Jun-15 at 11:36

            What I want to achieve: when clicking the add new step button the id "step1" will be added into HTML div and the value will also display step1 and if I click a second time it will increment so the id "step2" will be added into the second appended div and the value also will display step2

            what I did / problem: When I click the button for 2 times it appends id "step2" into all two div if I click four times it will append id "step4" to all appended div.

            It's because you are manipulating global .steplist instead of only the new elements. Also, your approach will produce a non-valid HTML, because id should be unique for each element, this approach will make all elements with the same id.

            So I'd suggest add id only to the root element of new added content like so:

            If you measure various distances on the image when the 'blob' is circular you get CSS to calculate what dimensions and what positioning (in % terms) the blob has in relation to the whole image. As the image is stretched, the blob will stretch accordingly.

            In this vanilla JS snippet the logo image is shown as the background to the div and the blob is its child div. This saves having to add another div into the DOM which wouldn't add more meaning.

            Collision detection depends on your needs.

            • Bounding boxes are simple and can detect if the x, y edges of each object are not within one another. This is fine for fast moving games and things where you don't necessarily require point precision.
            • Distance vectors are also simple and perfect solution for circle collisions. They calculate the difference in distance between two objects according to a radius prescribed with the hypotenuse of distX^2 + distY^2.
            • Compound bounding objects are harder to calculate, especially for concave areas on objects of arbitrary shape. There are too many notable and novel approaches to collision detection beyond these to remark on here.

            They're also increasingly complex depending on things like variability (if they're deformable objects, if they have particle seams, etc and 2d vs 3d object collision can be vastly different worlds as well. There are tons of articles, but I'll post one with implementation here

            How do a sort a array of void* that points to places with names?
            Asked 2021-Jun-15 at 02:51

            Basically there are rectangles (buildings) and circles (people).

            The task I need to do is basically, when a function "fg" is called, every circle that is inside a given radius needs to run to the closest rectangle, and after all the circles inside the radius finds a rectangle, I need to report on a .txt file the names of the circles that run to each rectangle sorted alphabetically.

            Such as:

            Rectangle A: c1 c2 c3

            Rectangle B: c7 c11 c20

            ...

            And so on...

            I need to store the addresses of the circles that run, on a vector of each rectangle. I tried to use qsort from stdlib.h, but maybe the function that i use to compare is wrong
