§ cycle_trampoline()
| void AirspeedSim::cycle_trampoline |
( |
void * |
arg | ) |
|
|
staticprotected |
Static trampoline from the workq context; because we don't have a generic workq wrapper yet.
- Parameters
-
| arg | Instance pointer for the driver that is polling. |
§ ioctl()
| int AirspeedSim::ioctl |
( |
cdev::file_t * |
filep, |
|
|
int |
cmd, |
|
|
unsigned long |
arg |
|
) |
| |
|
virtual |
Perform an ioctl operation on the device.
The default implementation handles DIOC_GETPRIV, and otherwise returns -ENOTTY. Subclasses should call the default implementation for any command they do not handle themselves.
- Parameters
-
| filep | Pointer to the NuttX file structure. |
| cmd | The ioctl command value. |
| arg | The ioctl argument value. |
- Returns
- OK on success, or -errno otherwise.
Reimplemented from cdev::CDev.
§ new_report()
| void AirspeedSim::new_report |
( |
const differential_pressure_s & |
report | ) |
|
|
protected |
add a new report to the reports queue
- Parameters
-
| report | differential_pressure_s report |
§ probe_address()
| int AirspeedSim::probe_address |
( |
uint8_t |
address | ) |
|
|
protected |
Test whether the device supported by the driver is present at a specific address.
- Parameters
-
| address | The I2C bus address to probe. |
- Returns
- True if the device is present.
§ read()
| ssize_t AirspeedSim::read |
( |
cdev::file_t * |
filep, |
|
|
char * |
buffer, |
|
|
size_t |
buflen |
|
) |
| |
|
virtual |
Perform a read from the device.
The default implementation returns -ENOSYS.
- Parameters
-
| filep | Pointer to the NuttX file structure. |
| buffer | Pointer to the buffer into which data should be placed. |
| buflen | The number of bytes to be read. |
- Returns
- The number of bytes read or -errno otherwise.
Reimplemented from cdev::CDev.
§ start()
| void AirspeedSim::start |
( |
void |
| ) |
|
|
protected |
Initialise the automatic measurement state machine and start it.
- Note
- This function is called at open and error time. It might make sense to make it more aggressive about resetting the bus in case of errors.
