Jeff Epler 09f6919c93 Add ability to read VOLTAGE_MONITOR on Pico W ... Because this must be treated like an in-use pin for all other purposes, unfortunately a special case must be added in shared-bindings. Multiple AnalogIn objects for VOLTAGE_MONITOR can be created (because in use tracking isn't working) but this causes no harm. Testing performed: Read the monitor, then imported wifi. When the pin state was insufficiently restored, the second step would fail with debug messages about do_ioctl timeout. ``` import analogio, board a = analogio.AnalogIn(board.VOLTAGE_MONITOR) print(a.value) import wifi ``` Closes: #7020		2022-11-08 09:37:15 -06:00
