Yielding data from an async task to a chunked response

How do I yield data to a chunked response from a async routine?

The code reads the adc like this:

```
async def read_adc(pin: microcontroller.Pin):
    with analogio.AnalogIn(pin) as adc:
        while True:
            local_value = (adc.value * 3.3) / 65536
            await asyncio.sleep(0.1) 
``` 

How can the local_value be yield'ed in a chunked response?
