Direction Needed for Structuring a Script

[Chris-24MAY60]

Hello, I am using an ESP32S3 to read uart data and condition it, using some computations, to be written into various files. The files contain values that will serve as meta-data to update some html files - to be served, via URL requests - to mobile devices. I have a Microdot server function (app) working beautifully to serve the various html and csv files. I also have the uartprocessing function working swimmingly. But I can't figure out how to pass control back & forth between the two functions. I (think) I would like the server to run for, say 2 seconds, then suspend its operation, (but not drop the port!) handing control to the uart_processing function, (which only needs tens of milliseconds to update any new uart data) ideally then handing-back control to the server function , which resumes serving .....and so back & forth it goes. I am guessing that "suspending" server operation may not be the conventional or preferred approach - since then it hinges on the URL request to keep pending. I haven't any experience with sharing files, locking files, sequential-vs-simultaneous operation of functions- and so am looking for guidance or best practices. I am a little surprised I'm struggling so!

Look into using asyncio. Microdot v2 uses asyncio. Couple this with asyncio.StreamReader(uart). See Peter Hinch's excellent tutorial and code: https://github.com/peterhinch/micropython-async

Thank you, Ned, I've noticed Peter has helped many. It isn't so much that I need to be told what to see - as I could use being shown where to look. This sounds like a great place you gave me to look. Chris
