Alex Young |
54:2e9bb1390c9c | 16 | * |
Alex Young |
54:2e9bb1390c9c | 17 | * Example firmware for communicating with an Xsens MTi-1 series motion |
Alex Young |
54:2e9bb1390c9c | 18 | * tracker (MT). |
Alex Young |
54:2e9bb1390c9c | 19 | * |
Alex Young |
54:2e9bb1390c9c | 20 | * The firmware uses the mbed-rtos library to provide RTOS features such as |
Alex Young |
54:2e9bb1390c9c | 21 | * memory pools and queues. A single thread (main) is used with reception of |
Alex Young |
54:2e9bb1390c9c | 22 | * data from the motion tracker via a UART handled by interrupts. |
Alex Young |

Alex Young |
54:2e9bb1390c9c | 24 | * \section Hardware setup |
Alex Young |
54:2e9bb1390c9c | 25 | * The firmware has been tested with a ST Nucleo F302R8 development board. |
Alex Young |
54:2e9bb1390c9c | 26 | * The Nucleo board should be connected to the MTi1 development board using the |
Alex Young |
54:2e9bb1390c9c | 27 | * Arduino compatible headers on the Nucleo board as follows: |
Alex Young |
54:2e9bb1390c9c | 28 | * |

Alex Young |
54:2e9bb1390c9c | 40 | * |
Alex Young |
54:2e9bb1390c9c | 41 | * \subsection Porting |
Alex Young |
54:2e9bb1390c9c | 42 | * To port to a different mbed platform only the serial Rx/Tx lines and the |
Alex Young |
54:2e9bb1390c9c | 43 | * reset line pins should need to be updated. |
Alex Young |
54:2e9bb1390c9c | 44 | * |
Alex Young |
54:2e9bb1390c9c | 45 | * \section Firmware Operation |
Alex Young |
54:2e9bb1390c9c | 46 | * The firmware starts by initializing the serial ports used to communicate |
Alex Young |
54:2e9bb1390c9c | 47 | * with the host PC and with the MT. During the initialization the MT is held |
Alex Young |
54:2e9bb1390c9c | 48 | * in reset using the nRST input. |
Alex Young |
54:2e9bb1390c9c | 49 | * |
Alex Young |
54:2e9bb1390c9c | 50 | * Once the firmware is ready to communicate with the MT the reset line is |
Alex Young |
54:2e9bb1390c9c | 51 | * released and the firmware waits for a wakeup message from the MT. If this is |
Alex Young |
54:2e9bb1390c9c | 52 | * not received within 1 second the firmware will try to restore communication |
Alex Young |
54:2e9bb1390c9c | 53 | * with the MT using a special restore communication procedure. |
Alex Young |
54:2e9bb1390c9c | 54 | * |
Alex Young |
54:2e9bb1390c9c | 55 | * When the MT is ready for communication the firmware requests the device ID |
Alex Young |
54:2e9bb1390c9c | 56 | * of the MT, and based on this determines which type of MTi is connected. |
Alex Young |
54:2e9bb1390c9c | 57 | * If the MT is an MTi-1 then it will be configured to send inertial and |
Alex Young |
54:2e9bb1390c9c | 58 | * magnetic measurement data. MTi2 and MTi3 devices have onboard orientation |
Alex Young |
54:2e9bb1390c9c | 59 | * estimation and will therefore be configured to provide quaternion output. |
