Hi,
I have two imx boards, MCIMX6Q-SDB and MCIMX8M-EVK.
I developed Android App. to get a sensor list of these boards.
1. MCIMX6Q-SDB
SensorList App. shows the sensor list of this board as follows.
--------------------------------------------------------------------------------
Number of Sensors=5
Freescale 3-axis Accelerometer
Type: TYPE_ACCELEROMETER
Vendor: Freescale Semiconductor Inc.
Version: 1
Resolution: 5.985504E-4
MaximumRagne: 19.6133
Power: 0.3
.......
--------------------------------------------------------------------------------
This information is same as that of sensor.cpp in $(MY_ANDROID)/vendor/nxp-opensource/imx/libsensors
static const struct sensor_t sSensorList[] = {
{
.name = "Freescale 3-axis Accelerometer",
.vendor = "Freescale Semiconductor Inc.",
.version= 1,
.handle = SENSORS_ACCELERATION_HANDLE,
.type = SENSOR_TYPE_ACCELEROMETER,
.maxRange = RANGE_A,
.resolution = CONVERT_A,
.power = 0.30f,
.minDelay = 2500,
.fifoReservedEventCount = 0,
.fifoMaxEventCount = 32,
.stringType = SENSOR_STRING_TYPE_ACCELEROMETER,
.requiredPermission = 0,
.maxDelay = 640000,
.flags = SENSOR_FLAG_CONTINUOUS_MODE,
.reserved = {}
},
...
2. MCIMX8M-EVK
SensorList App. shows no sensor information
--------------------------------------------------------------------------------
Number of Sensors=0
--------------------------------------------------------------------------------
sensor.cpp in $(MY_ANDROID)/vendor/nxp-opensource/imx/libsensors_sensorhub
has sensor information, but SensorList App. can't get this.
static const struct sensor_t sSensorList[] = {
{
.name = "Freescale Sensor Hub Accelerometer",
.vendor = "Freescale Semiconductor Inc.",
.version= 1,
.handle = SENSORS_ACCELERATION_HANDLE,
.type = SENSOR_TYPE_ACCELEROMETER,
.maxRange = RANGE_A,
.resolution = CONVERT_A,
.power = 0.30f,
.minDelay = 2500,
.fifoReservedEventCount = 0,
.fifoMaxEventCount = 0,
.stringType = SENSOR_STRING_TYPE_ACCELEROMETER,
.requiredPermission = 0,
.maxDelay = 640000,
.flags = SENSOR_FLAG_CONTINUOUS_MODE,
.reserved = {}
},
...
MCIMX6Q-SDB board has real H/W sensors, but MCIMX8M-EVK does not.
I think that the absence of real sensors has no effect to get the sensor list in sensors.cpp.
Is this correct?
Please help me to solve this problem.
How to get a sensor list from my MCIMX8M-EVK board in Android Sensor Framework?
Thanks very much in advance.
