◆ pup_ultrasonic_sensor_distance()
| int32_t pup_ultrasonic_sensor_distance |
( |
pup_device_t * |
pdev | ) |
|
Get the distance by a ultrasonic sensor.
Always returns 0 (error log is output) when an invalid sensor number is specified.
- Parameters
-
| pdev | PUP Device pointer to be inquired |
- Returns
- Distance in centimeters.
◆ pup_ultrasonic_sensor_get_device()
| pup_device_t * pup_ultrasonic_sensor_get_device |
( |
pbio_port_id_t |
port | ) |
|
Get the PUP device pointer of the ultrasonic sensor specified with the port ID.
If it fails, it outputs an error log and returns NULL.
- Parameters
-
| port | PUP port ID to be inquired. |
- Returns
- pdev PUP device pointer.
-
NULL PUP device pointer.
