Changing the Digitial IO to a DataDevice #270

Closed iandobbie closed 1 year ago

iandobbie commented 1 year ago

I have started to work on changing the DIO device to be a DataDevice. This will allow hardware to send input digital lines back to the remote server in real time.

This involves changing the device type and adding a few required functions, the most important being the _fetch_data call which returns data to the connecting machine

iandobbie commented 1 year ago

I have added a test line to the DIO simulation mode which toggles line 3 every 5 seconds and pushes the new value over Pyro.

Next steps:

Add to the Raspberry Pi implementation using its interrupt driven function call to wait for state changes on all input lines and push them when they occur.

This has been completed and merged in b6ddfa0dc10cdf7ef6a5b723054fb65bd8a83f31 Now all appears to work for simulation and the concrete raspberry pi implementation.
