Hi guys, I have in mind a project, to show the real time signal such as ECG, Spo2…in website via WIFI !!! Can you give me advice where should I begin to learn and can we do it at least ? If you’ve some information about this project, please give me a tutorial or a link that I can watch & learn step…

This should get you started [image] Photon running simple webserver & local communication Troubleshooting I would like to have a simple web server running on the photon. The server will populate a page with analog values it is reading and also have the ability to control f…

Thank you for your help. I’ll give it time to learn from now.

Which update frequency are you aiming for ? You can get 1update per second using .publish and listening via server sent events, if that is not fast enough you need to do some manual magic. 1st improvement could be hosting a website on the photon and calling a ajax endpoint often, that could get yo…

Thank you MORA for these details information. With this simple example :smile: for(i=0; i<10; i++) { //send data to website delay(20); //delay 20ms } Can you make an easy & simple tutorial to plot this sawtooth wave for me ? If the plotting step cost you quite too much time, I just need t…

20ms is pretty fast but doable… Either you need a tcp connection that stays open and you just send more data, or you can use udp. UDP does not gurantee delivery, especially if going over the internet, but if your data is for display anyway, a lost value may be preferable to a lagged value. I made…

I’m sorry but I had not learned Python yet :expressionless: Can we display number from 0 -> 10 in HTML from your demo above ? :expressionless: I had run the code in Photon, and open the HTML, “connected” but nothing else been displayed :frowning:

Did you use the ip above for the html or just opened it locally ? Since we are using raw network packages, you need some sort of server inbetween the photon and the webclient. I dont know a lot of python myself, I mostly use PHP or nodeJS, but python is very nice when dealing with lots of traffic,…

Thank you for your solution at the bottom, but why we have to flash the Photon again after click “Connect” in HTML file, these number appear ok, then if we click “Disconnect” and “Connect” once again, this time these number will not show just like that ? Basically we have to flash Photon again and a…

You dont have to flash it again, I just didnt include a loop() function, partly as a safety feature if the code was bad, you can just reset the photon and it will upload again. The connect/disconnect buttons controls your webbrowsers connection to the websocket server, not the photon directly. The…

I don’t know where I need to put the python code to, now I only use HTML and Photon, seems like ok, right ? I saw you wrote about the “intermediate program”, what is it ? Can you give me some information ? This is what I get after running your code, how can we remove the whole weird character righ…
