ft5x06 — Touch Screen Driver

The ft5x06 module provides a driver for the FT5x06 capacitive touch screen controller used on the OpenMV Pure Thermal.

class FT5X06 – Touch Screen Controller

class ft5x06.FT5X06(i2c_addr: int = 0x38)

Creates a touch screen controller object.

i2c_addr is the I2C address of the FT5x06 controller.

get_gesture() → int

Returns the current gesture. The return value is one of the ft5x06.GESTURE_* constants.

When a callback is registered via FT5X06.touch_callback() this method should only be called from within the callback.

get_points() → int

Returns the current number of touch points (0-5).

When a callback is registered via FT5X06.touch_callback() this method should only be called from within the callback.

get_point_flag(index: int) → int

Returns the current state of the touch point at index (0-4). The return value is one of the ft5x06.FLAG_* constants.

When a callback is registered via FT5X06.touch_callback() this method should only be called from within the callback.

get_point_id(index: int) → int

Returns the id of the touch point at index (0-4). The id is a numeric value that allows tracking a touch point across updates as points are added and removed.

When a callback is registered via FT5X06.touch_callback() this method should only be called from within the callback.

get_point_x(index: int) → int

Returns the x pixel position of the touch point at index (0-4).

When a callback is registered via FT5X06.touch_callback() this method should only be called from within the callback.

get_point_y(index: int) → int

Returns the y pixel position of the touch point at index (0-4).

When a callback is registered via FT5X06.touch_callback() this method should only be called from within the callback.

touch_callback(callback: object) → None

Registers callback to be invoked on a touch event. The callback receives one argument: the current number of touch points (0-5).

Pass None as callback to disable the callback. While a callback is registered, do not call FT5X06.update_points() outside of the callback.

update_points() → int

Reads the touch screen state and returns the number of touch points (0-5).
