Mydin-advanced-usage

Abstract

Before going into the details of the various controlers and backplanes, it may be opportune to learn some advanced behaviors of the MyDin asyncio implementation.

RUN_APP

RUN_APP pin is used to stop the MyDin software stack (or script execution after a reboot).

It is a convenient way to recover the control on the module when script goes wrong. It would also offer the full access to REPL.

When setting the RUN_APP pin to the "Stop" position (so tied to ground) while the MyDin software is already running, the code may takes up to 3 seconds to terminates.

Exception handling

An exception occuring in the userloop task will be captured and will ends the
