Is this the proper use for switch case? I am looking to make a simple utility for reporting back Wireless AP info, Baud Rate, and Mode of a ESP8266 module.



When the program loads it gives the user a small menu of option and based on the input of the user (1,2 or 3) it will run the associated AT command stored as a variable in the code.



Will this work as is? Or am I missing something to send the command and get the data back?



void loop() 

if (Serial.available() > 0) 
input = Serial.read();
Serial.flush();

switch (input) 
 case '1':
 Serial.println(baud);
 break;

 case '2':
 Serial.println(wap);
 break;

 case '3':
 Serial.println(amode);
 break;

 default:
 Serial.print("'");
 Serial.print((char)input);
 Serial.println("' is not a command!");



The baud, wap, and amode commands are setup as follows:



const char* wap = "AT+CWLAP";
const char* baud = "AT+CIOBAUD";
const char* amode = "AT+CWMODE";

  • I am stuck. The code works to send the commands to the serial monitor but it's not returning the information it should. It just shows the command.

Greedy Best First Search implementation in Rust

Image
Clash Royale CLAN TAG #URR8PPP .everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty margin-bottom:0; up vote 1 down vote favorite I have implemented a Greedy Best First Search algorithm in Rust, since I couldn't find an already implemented one in the existing crates. I have a small pet project I do in Rust, and the Greedy BFS is at the core of it. The algorithm is designed to be as flexible as possible. Theoretically, this algorithm could be used as a greedy depth-first search or as a greedy a*. I want to design a good algorithm that I could later use in any other project needing it, not only this one. I am quite new to Rust and this is the second project I do in this language. Also, I am new to writing optimized algorithms. Since this search will be called often, my main concern is performance. What are some tips and tricks to make the algorithm perform better? Of course any other critique and comment is welcome. Bellow is the code: //! Here is

Function to Return a JSON Like Objects Using VBA Collections and Arrays

Image
Clash Royale CLAN TAG #URR8PPP .everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty margin-bottom:0; up vote 1 down vote favorite My goal is to create a compact function that can create a JSON Like object from JSON string. I want a function with a small footprint that I or anyone who wants to use it, can simply paste into a module and use. At 61 lines of code, I am happy with its size and portability. Here is an image of JSON Object created from string data using a ScriptControl . Although the Locals Window displays the properties and values correctly, the object itself is extremely difficult to work with. This image shows an object created using getJSONCollection . Because it is made of VBA Collections and Arrays, it is very easy to work with. Option Explicit Private Function getJSONCollection(ByVal Value As Variant, Optional ScriptEngine As Object) As Variant Const DELIMITER As String = "||" Dim col As Collection, JSON As Object, KeyNam

C++11 CLH Lock Implementation

Image
Clash Royale CLAN TAG #URR8PPP .everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty margin-bottom:0; up vote 1 down vote favorite 1 As a hobbyist programmer I have been reading "The Art of Multiprocessor Programming" (Herlihy, Maurice; Shavit, Nir) and converting the Java spin locks into C++ - I have enjoyed this and learned a lot. I have implemented the CLH spin queue lock (due to Travis Craig, Erik Hagersten, and Anders Landin) but I feel unhappy about the way that I have the raw pointers interacting with smart pointers and would be grateful for code review advice. As I understand it I must use a smart pointer, in this case std::unique_ptr , for my thread local node pointer or the lock will not deallocate properly and the clh_lock will leak. But... I also have no choice but to use a raw atomic tail queue pointer in order access the atomic exchange member function. Therefore, I have to come up with some combination of either, raw or smart
