## asp5033

Source: [drivers/differential\_pressure/asp5033](https://github.com/PX4/PX4-Autopilot/tree/main/src/drivers/differential_pressure/asp5033)

### Description

Driver to enable an external \[ASP5033] (https://www.qio-tek.com/index.php/product/qiotek-asp5033-dronecan-airspeed-and-compass-module/) TE connected via I2C. This is not included by default in firmware. 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.
