WIP - Interrupt-Driven Scheduling #606
Conversation
|
There is now a working demo of an async echo. This was tested on my arduino nano33, using the coroutines scheduler. The tasks scheduler is still not yet working with this. Also, we will need to update the timing code on all platforms to accommodate a source of wakeups that is not the timer. |

I do not quite understand why this prevented it from working. Can someone explain what is going on?

Probably because UART0 is already configured as part of the runtime setup on most platforms. Otherwise we cannot do any println() statements on panic etc.

As of now, this compiles and runs with the latest version of #607 . |

Why 2 calls to cond.Wait() here?

To test that subsequent calls will not block until the condition is cleared.

This PR is not going to be merged, but I am slowly ripping stuff out of here to make other smaller PRs. |

This PR attempts to add a mechanism for an interrupt to resume a goroutine.
