@ -62,33 +62,4 @@ The tinyusb examples already include a "WebUSB serial" example.
|
||||
Basically, this feature was ported into CircuitPython by pulling code snippets out of the
|
||||
tinyusb example, and putting them where they best belonged in the CircuitPython codebase.
|
||||
|
||||
There was one complication:
|
||||
|
||||
tinyusb uses C preprocessor macros to define things like USB descriptors.
|
||||
|
||||
CircuitPython uses a Python program (tools/gen_usb_descriptor.py) to create USB descriptors (etc.)
|
||||
using "helper objects" from another repo (adafruit_usb_descriptor). This means some of the example
|
||||
code had to be adapted to the new programing model, and gen_usb_descriptor gained new command-line
|
||||
options to control the generated code.
|
||||
|
||||
The generated files go into the "build" directory, look for autogen_usb_descriptor.c and
|
||||
genhdr/autogen_usb_descriptor.h.
|
||||
|
||||
|
||||
Also worth pointing out - the re-use of the CDC connect/disconnect mechanism is not actually part
|
||||
of the WebUSB standard, it's more of "common idiom". We make use of it here because we need to know
|
||||
when we should be paying attention to the WebUSB serial interface, and when we should ignore it..
|
||||
|
||||
## Possible future work areas
|
||||
|
||||
The current code uses the existing Python infrastructure to create the Interface descriptor, but
|
||||
simply outputs the code snippets from the original tinyusb demo code to create the WEBUSB_URL,
|
||||
BOS, and MS_OS_20 descriptors. I suppose additional work could be done to add these to the
|
||||
adafruit_usb_descriptor project, and then gen_usb_descriptor.py could be modified to make use
|
||||
of them.
|
||||
|
||||
Program gen_usb_descriptor.py creates objects for most interface types, regardless of whether or
|
||||
not they are actually enabled. This increases the size of a generated string table. I made the
|
||||
new vendor-interface-related code not do this (because some of the ARM platforms would no longer
|
||||
build), but I did not go back and do this for the other interface types (CDC, MIDI, HID, etc.)
|
||||
Some FLASH savings are probably possible if this is done.
