Can I program microcontrollers in Kotlin?



Is it possible somehow to program Arduino or ESP8266 microcontrollers on Kotlin?
Same question about single-board computers (i.e. Raspberry Pi).





kotlin-native only supports a few architectures. AVR- and Cortex M3-based Arduinos aren't supported, and I don't think ESP8266 will ever be since LLVM doesn't even support it. Even if they were, you'll have a hard time running anything bigger than a Hello World program given Kotlin's runtime, memory management, and the tiny amount of memory in an Arduino or a ESP8266. On the other hand, a Raspberry Pi is the same as any other ARM-based Linux computer so there's no issue running Kotlin and the JVM directly.

Assuming your use of the term single-board computers implies something that it can run an operating system for example linux or windows, then you have the resources on board to do such a thing, yes. How much work you have to put in, might exceed the work needed to just learn a more natural language for baremetal work.

This is generally true for a number of non C/ASM languages, even C++ to some extent. The backend required which is generally handled by the system or various sized libraries on top of the system is more work to port than just using a language that is light on the system (ASM, C, Pascal, etc). Now some interpreted languages can be compiled (Pascal, Python, JAVA, kotlin, etc) but those languages may have built in system calls, that would then have to be supported by the baremetal backend and/or not supported and fault if encountered.

Yes. Microcontrollers are still computers. if python can be used in Raspberry. then Kotlin can also be used.



First you need compile, JVM(Open source e.g OpenJDK) with that microcontroller toolchain.
Then run the image in the microcontroller.
Now create a kotlin file, compile it and run it with that JVM.
Thats if the microcontroller runs on a kernel e.g linux



Make sure that microcontroller have enough memory.





The problem with microcontrollers is they are very resource limited, being able to squeeze a complete enough JVM is the problem, while you will find some big mcus, a large percentage of them will not work.

Note that while some flavors of Raspberry Pi are in the price range of an MCU eval/breakout board the broadcom chip is in no way a microcontroller. The board has more than enough resources, and you can if you so desire attempt to port a baremetal complete enough JVM, and then run on top of that.

In general it is FAR better to use languages that are more suited for the task C/asm being the most common by a very wide margin.

Firebase Auth - with Email and Password - Check user already registered

Clash Royale CLAN TAG #URR8PPP Firebase Auth - with Email and Password - Check user already registered I want to check when a user attempts to signup with createUserWithEmailAndPassword() in Firebase user Authentication method, this user is already registered with my app. createUserWithEmailAndPassword() 8 Answers 8 To detect whether a user with that email address already exists, you can detect when the call to createUserWithEmailAndPassword () fails with auth/email-already-in-use . I see that @Srinivasan just posted an answer for this. createUserWithEmailAndPassword () auth/email-already-in-use Alternatively, you can detect that an email address is already used by calling fetchSignInMethodsForEmail() (previous called fetchProvidersForEmail() ). fetchSignInMethodsForEmail() fetchProvidersForEmail() When the user trying to create an user with same email address, the task response will be "Response: The email address is already in use by another account." mFirebas

Dynamically update html content plain JS

Clash Royale CLAN TAG #URR8PPP Dynamically update html content plain JS So I have a script bound in my index.html, which literally has to fetch an array of jsons from an api, then dynamically update my page when get response. But as a result I'm getting an as the only update of my page. here is my script fetch(url) .then((resp) => resp.json()) .then((resp) => resp.results.forEach(item => fetch(item.url) .then((response)=> response.json()) .then((response) => pokeArr.push(response)) .catch(console.log) ) ).catch(console.log) const filler = () => if(!pokeArr) return 0 pokeArr.map((i,j)=> return `<tr>$i.name</tr>` ) const pokeindex = () => document.getElementById('a').appendChild(document.createElement(filler())) pokeindex() When I'm consoling it, I can see in the console all the responses I get, so I'm at least doing the fetching part right. What's parberakan ? What's pokeArr ? – T.J. Crowder Aug 8 at 12

Creating a leaderboard in HTML/JS

Clash Royale CLAN TAG #URR8PPP Creating a leaderboard in HTML/JS I'm trying to create a top 10 leaderboard, for now, I've only implemented 3 players, but I'm coming across an issue. My script doesn't seem to be outputting anything on webpage. The purpose of the script is to compare 3 arrays, player1,player2,and player3 solely based off of score. Which is the 2nd index of each array. I want the script to list the players in order of highest score. This method doesn't really seem to be efficient, especially when I'll have to add 7 more players. Could someone suggest perhaps an easier approach, as well as show me why my script wont output the info. Here's the JS function leaderboard() { var player1 = name:"Thomas",date:"01/23/18",score:"201"; var player2 = name:"Michael",date:"03/24/17",score:"943"; var player3 = Name:"Lisa",date:"06/04/18",Score:"79"; if(player1[2]&g
