gForceSDK

Brief

This repository include gForce SDK dll files and some simple examples.

F.A.Q.

How to get accelerate speed data of the gForce by gForceSDK?

1. Implement HubListener interface

  class HubListenerImpl : public HubListener{...}

2. Config Accelerate(optional)

Call DeviceSetting::setAccelerateConfig(...) to configure ACC

3. Open ACC Data Notification

Call DeviceSetting::setDataNotifySwitch(...) to open ACC

4. Extract the data of acceleration

void onExtendedDeviceData(SPDEVICE device, DeviceDataType dataType, gfsPtr<const vector<GF_UINT8>> data) override
{
  switch (dataType) {
    case DeviceDataType::DDT_ACCELERATE:
    //... extract accelerate speed  from 'data'
    //                    Data format accelerate speed
    // *--------------------------------*---------------*---------------*
    // |ACC_X(data type = long(4 Byte)) | ACC_Y(...)    | ACC_Z(...)    |
    // *--------------------------------*---------------*---------------*
    // |accelerate speed at X axis      |...            |...            |
    // *--------------------------------*---------------*---------------*
    //
      auto ptr = data->data();
      long acc_x = *(reinterpret_cast<const long*>(ptr));
      long acc_y = *(reinterpret_cast<const long*>(ptr + 4));
      long acc_z = *(reinterpret_cast<const long*>(ptr + 8));
    break;
    case DeviceDataType::DDT_GYROSCOPE:
      //... extract gyroscope data form 'data'
    break;
    default:
    break;
  }
}
