* Add bus, port_numbers and speed to USB devices. Allows for
differentiating identical devices.
* Autodetect display and adjust if widescreen
* Enable I2S DAC via its reset pin
* Show keyboard emoji in status bar. (Only works over serial connection
now. Built in font doesn't have the emoji.)
We use it to open endpoints as they are used. Fetching the descriptor
as needed can cause issues with devices that we're expecting a control
packet while another transaction was ongoing. Specifically, a usb
thumb drive didn't expect a control transaction while doing a SCSI
transaction.
This PR also aborts transactions on timeout or ctrl-c interrupt. It
doesn't always recover though...
Originally, black_bindings found each contiguous "//|" block and sent
it to black independently. This was slower than it needed to be.
Instead, swap the comment prefix: when running black, take off
"//|" prefixes and put "##|" prefixes on all un-prefixed lines.
Then, after black is run, do the opposite operation
This more than doubles the overall speed of "pre-commit run --all",
from 3m20s to 55s CPU time on my local machine (32.5s to under 10s
"elapsed" time)
It also causes a small amount of churn in the bindings, because
black now sees enough context to know whether one 'def' follows another
or ends the 'def's in a 'class'. In the latter case, it adds an extra
newline, which becomes a "//|" line.
I'm less sure why a trailing comma was omitted before down in
rp2pio/StateMachine.c but let's roll with it.
This allows you to list and explore connected USB devices. It
only stubs out the methods to communicate to endpoints. That will
come in a follow up once TinyUSB has it. (It's in progress.)
