pyb — functions related to the board¶
pyb module contains specific functions related to the board.
Return True if USB is connected as a serial device, False otherwise.
This function is deprecated. Use pyb.USB_VCP().isconnected() instead.
hid((buttons, x, y, z))¶
Takes a 4-tuple (or list) and sends it to the USB host (the PC) to signal a HID mouse-motion event.
This function is deprecated. Use pyb.USB_HID().send(...) instead.
Print out lots of information about the board.
Set the filename of the main script to run after boot.py is finished. If this function is not called then the default file main.py will be executed.
It only makes sense to call this function from within boot.py.
mount(device, mountpoint, *, readonly=False, mkfs=False)¶
Mount a block device and make it available as part of the filesystem.
devicemust be an object that provides the block protocol:
readblocks(self, blocknum, buf)
writeblocks(self, blocknum, buf)(optional)
writeblocksshould copy data between
bufand the block device, starting from block number
blocknumon the device.
bufwill be a bytearray with length a multiple of 512. If
writeblocksis not defined then the device is mounted read-only. The return value of these two functions is ignored.
countshould return the number of blocks available on the device.
sync, if implemented, should sync the data on the device.
mountpointis the location in the root of the filesystem to mount the device. It must begin with a forward-slash.
True, then the device is mounted read-only, otherwise it is mounted read-write.
True, then a new filesystem is created if one does not already exist.
To unmount a device, pass
Noneas the device and the mount location as
Get or set the UART object that the REPL is repeated on.
Return a 30-bit hardware generated random number.
Sync all file systems.
Returns a string of 12 bytes (96 bits), which is the unique ID for the MCU.
