sensors_module_t Struct Reference
#include <
sensors.h
>
Every hardware module must have a data structure named HAL_MODULE_INFO_SYM and the fields of this data structure must begin with
hw_module_t
followed by module specific information.
Definition at line
1149
of file
sensors.h
.
Enumerate all available sensors. The list is returned in "list".

int(* set_operation_mode)(unsigned int mode)
|
Place the module in a specific mode. The following modes are defined
0 - Normal operation. Default state of the module. 1 - Loopback mode. Data is injected for the supported sensors by the sensor service in this mode.
-
Returns
-
0 on success -EINVAL if requested mode is not supported -EPERM if operation is not allowed
