### Опис

Драйвер для включення зовнішнього [ASP5033]
(https://www.qio-tek.com/index.php/product/qiotek-asp5033-dronecan-airspeed-and-compass-module/)
TE підключається через I2C.
За замовчуванням це не включено до прошивки. It can be included with terminal command: "make <your_board> boardconfig"
or in default.px4board with adding the line: "CONFIG_DRIVERS_DIFFERENTIAL_PRESSURE_ASP5033=y"
It can be enabled with the "SENS_EN_ASP5033" parameter set to 1.
