UIFLOW2 Example:

class FingerUnit

Constructors

class FingerUnit(id: Literal[0, 1, 2] = 1, port: list | tuple = None)

Create a FingerUnit object.

参数:

id – The ID of the UART, 0 or 1 or 2.
port – UART pin numbers.

UIFLOW2:

Methods

FingerUnit.sleep() → bool

After calling this method successfully, FPC1020A will not be able to respond to any messages.

返回:: True if the command was successful, False otherwise.

UIFLOW2:

FingerUnit.get_add_mode() → int

In the no-repeat mode, only one user can be added with the same finger, and an error message will be returned if the second round of adding is forced.

返回:: mode (0: no-repeat mode, 1: repeat mode)

UIFLOW2:

FingerUnit.set_add_mode(mode: int) → int

In the no-repeat mode, only one user can be added with the same finger, and an error message will be returned if the second round of adding is forced.
