TouchScreen class

C++ defination code:
class TouchScreen

def __init__(self, device: str = '', open: bool = True) -> None

Construct a new TouchScreen object

item	description
type	func
param	device: touchscreen device path, you can get devices by list_devices method, by default(value is NULL(None in MaixPy)) means the first device open: If true, touchscreen will automatically call open() after creation. default is true.
static	False

C++ defination code:

TouchScreen(const std::string &device = "", bool open = true)

def open(self) -> maix.err.Err

open touchscreen device

item	description
type	func
return	error code, err::ERR_NONE means success, others means failed
static	False

C++ defination code:
err::Err open()

def close(self) -> maix.err.Err

close touchscreen device

item	description
type	func
return	error code, err::ERR_NONE means success, others means failed
static	False

C++ defination code:
err::Err close()

def read(self) -> list[int]

read touchscreen device

item	description
type	func
attention	This method will discard same event in buffer, that is: if too many move event in buffer when call this method, it will only return the last one, and if read pressed or released event, it will return immediately.
return	Returns a list include x, y, pressed state
static	False

C++ defination code:
std::vector<int> read()

read touchscreen device

item	description
type	func
attention	This method will return immediately if have event, so it's better to use available() to check if have more event in buffer, or too much event in buffer when your program call this read() interval is too long will make your program slow.
return	Returns a list include x, y, pressed state
static	False

C++ defination code:
std::vector<int> read0()

def available(self, timeout: int = 0) -> bool

If we need to read from touchscreen, for event driven touchscreen means have event or not

item	description
type	func
param	timeout: -1 means block, 0 means no block, >0 means timeout, default is 0, unit is ms.
return	true if need to read(have event), false if not
static	False

C++ defination code:
bool available(int timeout = 0)

def is_opened(self) -> bool

Check if touchscreen is opened

item	description
type	func
return	true if touchscreen is opened, false if not
static	False

C++ defination code:
bool is_opened()
