+There are several examples with the LPS22HH library.
+* LPS22HH_DataLog_Terminal_I2C: This application shows how to get pressure and temperature data from the LPS22HH sensor over I2C and print them on terminal.
+* LPS22HH_Datalog_Terminal_I3C: This application shows how to use the LPS22HH sensor over I3C using SETDASA.
