How to raise a server on a microcontroller?

Question

Arduino

There is esp8266. You need to make a web server out of it, where you can upload a site with a graph, which in turn will display data from the json file stored in the microcontroller, which in turn will take data from the sensors and write them to this same json file.

Answer 1

• You can write everything yourself using the Espressif SDK
  You can also use ready-made firmware, there are enough projects on GitHub.
  The choice is yours.

Answer 2

If you do not need a full-fledged server, then giving the page via http is as easy as shelling pears. Under your controller, I have nothing, look for examples on the net. It is necessary to lift TCP/IP. STM32 has the simplest web server in examples.
