This project implement a Http server on Sparkcore itself. Once compiled into the Web IDE, the server will be available at http://IP-SPARKCORE (port 80 by default)
My Github : HTTP server (REST & JSON) on Spark core
I managed to flash first time using web IDE. But I am not able to Flash it again. Only on commenting out the ws.loop(); IDE is able to flash the core.
What’s your Spark firmware ?
In IDE [Setting]
My FW is version 0.21
It is 0.2.1. What I have noticed is – If I am making use of Spark Tinker functions, like digitialread etc, I am not able to flash the Core from IDE. I either need to comment out Spark tinker functions or ws.opp(); in order to flash the core from IDE.
What is ws.opp() function ? ws.loop() ?
What error is displayed in debug build (the bottom of the IDE)?
Sorry it was a typo… ws.loop();
There was one error with my code. It is getting flashed now.
Captain… Attempting to test your application but getting compile errors… hard for me, possibly easy for you to solve.
\core-firmware\build/…/inc/HttpResponse.h:50: undefined reference to
HttpResponse::DEFAULT_CONTENT_TYPE' obj/src/application.o: In functionWebServer::loop()’:
and similar for
undefined reference to
HttpRequest::HttpRequest()' undefined reference toHttpRequest:: parse(char)'
undefined reference to `HttpRequest::URL() const’
and so on…
Please advise if you can.
I am using NetBeans as a local compiler rather than the cloud. I am off to compile on the cloud hoping to find the solution there.
Thank you very much
Hye @LZHenry ,
Sorry for my english, I am a french.
I dont know compile the project without the Web IDE. I do not know Netbeans.
Captain… I am from the US and wish I could speak/write other languages!!!
Transferred your code to the cloud and was able to load into the CORE. Now I need to understand how to use the browser to display the WEB page.
- I assume that with NetBeans compiler I am not properly picking up a typedef for one of your variables; the cloud is properly recognizing the structures. I need to search and learn.
Thank you for sharing the project.
Hello Sir, I tried to flash the code using web IDE. it flashed properly, but i m not able to open the webpage while i am connected to the same network to which core is connected. In the video, you have used 192.168.1.31… I tried to access using this url but it was not working. How can I know or get the IP address of the server implemented in the core, printed on the screen? How to use “serial.print”? Please help.
you must use a network scanner to identify the Spark core IP address of your subnet.
@prashuk, here is a topic on different ways to get your Core’s IP address:
thanks peekay !!
Serial.print(" Local IP: ");
to get my IP.
Is there any way to connect my spark core with proxy server or to set the proxy to connect my core with wi-fi ??
I get everything to validate and upload, but when I go to the ip address in the browser, the website looks nothing like the examples in the video. Instead, I get a static line of text saying:
or at analogue:
What am I doing wrong?
Actually I changed the GUI to optimize memory.
You can use Old1-spark-Web-Tinker.ino in Github file for old GUI.
Ah oke, than this isn’t what I’m looking for. I want a constant stream of analog input values on a website. Looking into TCPserver and UDP now.
That’s constant stream, but with http client query.
Don’t try to refresh because core down.
