DRDY pin for HTS221 on B-U585I-IOT02A?

[Bob McWhirter]

Having previously worked with the STM32L4S5 IOT board with an HTS221 on it, I'm familiar with the I2C interface and the HTS221's DRDY exti pin.

In the reference manual for the STM32U585-based IOT board, though, there is a giant blank on the I/O line for the DRDY interrupt pin.

Is this line not actually hooked up between the HTS221 and the STM32U5, or is this an oversight in the manual?

Check the board schematic. To me data ready for humidity are less critical due to the humidity response speed of the sensor, respective to pressure ones.

Ah, thanks. Didn't think to look under the CAD Resources section.

Sure enough, DRDY is NC'd.

Thanks!
