A Class to interface to the SMI540 over SPI.
This class interfaces with the BOSCH SMI 530/540 over SPI using an XDIMAX Sub20 interface device.
| Smi540::Smi540 | ( | std::string | sSub20Serial | ) |
Constructor initializes Sub20 device and SMI540ies.
Detects connected Sub20 devices and SMI540ies. Initializes the Sub20 device and loads configures the SMI540 with the specified bandwidth and max acceleration range. On request it performs sensor calibration
| sSub20Serial | Requesting desired sub20 device to be opened |

| Smi540::~Smi540 | ( | ) | [virtual] |
Destructor closing all open connections.
Closes open SPI connections and disables the Sub20 device. Disposes any dynamic structure in the heap.

| void Smi540::confsens_on_sub20 | ( | OneSub20Config * | pOneSub20Conf | ) | [private] |
Configures specified SMI540ies according to the default or user settings.

| void Smi540::GetMeasurements | ( | std::list< OneSmi540Meas > & | list_meas | ) |
Polls one measurement from all SMI540 defined in std::list<OneMulSmiMeas>&.
Iterates through all detected SMI540ies on all connected Sub20 devices and sends a measurement request to the respective sensor. In case of calibration request, any received measurement is used to calibrate the sensor. NOTE: As the EEPROM can only handle a limited amount of write cycles, the calibration routine only allows one Sub20 device to be connected for the calibration mode to be executed successfully.
