Interactive console with operational code



  • Hello

    I've worked with esp32 in C and there is a capability where you can add a console component to your esp32 C app.

    Its handy to interact with your code while its running. You create new commands and these commands can call functions in your firmware.

    On pycom if hit ctrl-c in my app, I can interact with the python interpeter to import files and then run them. However I can't interact with them afterwards. Is there a method similar to the C method for esp32 to get something similar? Perhaps its just as simple to periodically call get input and write my own console. Before I do that I was wondering something already exists. Any pointers would be grand.

    I'm particulary interested in this as I explore bluetooth on pycom.

    Given that C is a compiled language, this is hard to understand for me. So I assume it's some kind of firmware/application package which is running in the device. Still, the ESP32 does not have a general purpose Operating System.
    If you want to have the Python console while an application code is running, you can start that application in a new thread and terminate the thread which started it. Then you will get the REPL prompt again. But this is not general multitasking, just a method to run several tasks at the same time.

    Hi,
    Im not exactly sure what you mean, but it is possible to type python commands into the REPL window after clicking run. If I create a code that does:

    include time
    while(1):
        time.sleep(1)
    

    And then click run, the >>> dissappear, but it is still possible to execute python commands in the microcontrollers' spare time. Only struggle is when your device keeps printing in between.
