Will the ESP8266 handle a server with graphs refreshed 2 times per second?

Hello

I have just ordered an ESP8266 chip from the web.
Unfortunately all the examples given on the web are quite simple.
I am wondering if it is possible to do something more challenging and if the computing power of the ESP chip will allow it:

- Is it possible to make a server with a page displaying data in the form of graphs? I mean Simple graphs for about 4 variables. How to do this most efficiently on esp? PHP HTML? The graphs would have to be refreshed at least 2 times per skecond.

- I currently have a project that sends data to the computer via UART.
The speed of this communication is 921600 bps. Can the ESP chip operate at this UART speed? Will the computer be able to receive this data over WiFi?

By a slight cheat: transfer data and draw in the browser with JavaScript.
A little slower, but without JS: SVG.

Yes.

Rather, the question is whether the ESP will be able to send this data....

ESP in the form not of a server but of a client and for this something similar to this e.g. http://techfreak.pl/nettemp/ or it remains to write your website in php. Regards

What is the maximum transmission rate achieved by the ESP between the UART and WiFi ?

There are perhaps some examples of diagrams in java script ?

Speeds above 230400, are possible to communicate when the clocking is set to 80Mhz.

Added after 51 [seconds]:

Speeds above 230400, are communicable when the clocking is set to 80Mhz.

ok, thanks for your help

I am still wondering how to solve this problem with the charts.

I would like the ESP8266 to act as something like a server, but which only provides data.
The client (computer or phone) would have to read this data from the ESP8266 and draw graphs based on it. This solution would relieve the ESP chip and the drawing of the graphs could be handled by the computer or phone.
All data is to be local without sending the data to the "cloud".


-What do I need to program on the Arduino side? (I have the Adruino IDE and know the C language quite well)
-On the client side, do I need to write an application that will only work on the computer or maybe some page in PHP/HTML/Javascript ?
I would like it to work on the computer and on the phone from a web browser.

For good measure, everything can be done as a web page, on an ESP. For graphics, you need a bit more space, so think of the ESP8266-13. ESP supports graphics, you can draw something there. In LUA and EPS Basic, there are examples in the help. I admit that I haven't touched graphics yet, so I'm only suggesting the possibility, but I won't confirm the effectiveness. Have a look at the Reference at this link ESP Basic Graphics

Take a peek at an example from Help:
Clock

But I don't mean weather station style graphs.
These are supposed to be graphs drawn live and refreshed several times a second, e.g. with acceleration values

The ESP8266 is a pretty powerful chip. 80Mhz is really a lot, plus it's very easy to get it to work at 160Mhz. The only thing it may lack is support for floating point operations.

But - using this chip only as a "modem" and connecting to it by 20x less efficient chip (slightly counting), like some Arduino is just a sin... For this chip you can easily load your program, written from the beginning in C/C++. To make it easier, instead of writing directly in SDK, I recommend frameworks like "Sming" or "PlatformIO".
As for what you specifically need (from the first post - a web server, serving dynamic graphs) - on the esp8266 you can easily run a pretty efficient web server, serving JS files and capable of handling webservices. With such technologies you can, for example, make an oscilloscope to display a graph on a web page (not to mention simpler projects).
With JavaScript, the PC is defacto responsible for the graphics, and the web server just "sends" the data to be plotted in a separate TCP session.
I recommend this project as a "base for expansion" - https://github.com/Spritetm/esphttpd

Then put the server on an Android, why torture yourself with an ESP8266. You can buy a tablet for under £100.

Katy yourself? With that kind of attitude, then just go to the shop and buy/search for a ready-made solution. Besides, 100 PLN is much more than about 10 PLN (and you can buy ESP8266 modules for that much). Plus the size of such a solution - there is no comparison here.
This is probably a bit out of the spirit of the electrode? But maybe I don't know, I don't know, I rarely visit here....

A web server with Lua scripting support can be set up on the ESP8266 ( nodemcu-httpserver , lhttpd ) or Python ( MicroPython ). I wonder when someone will implement support for PHP scripts

Websocket is convenient for this. The server just sends the measurement data and the processing and drawing of the graphs is handled by an application e.g. in JS running in the browser on the client side. You can draw a continuous infinite graph this way, e.g. an ECG.

Here is an interesting video on the ESP8266 and WebSockets:
