Here you will find the code and project files corresponding to the I2C-Accelerometer project. The accelerometer/magnetometer is connected to the I2C port, although bot the accelerometer and magnetometer are contained within a single package, they must be initialized individually. In this example the measurements from both devices (X,Y and Z axis) is performed and displayed at the serial terminal. In order to compile the project, the following library must be imported: FXOS8700Q.h Code: #include "mbed.h" #include "FXOS8700Q.h" //I2C lines for FXOS8700Q accelerometer/magnetometer FXOS8700Q_acc acc( PTE25, PTE24, FXOS8700CQ_SLAVE_ADDR1); FXOS8700Q_mag mag( PTE25, PTE24, FXOS8700CQ_SLAVE_ADDR1); //Temrinal enable Serial pc(USBTX, USBRX); MotionSensorDataUnits mag_data; MotionSensorDataUnits acc_data; int main() { float faX, faY, faZ; float fmX, fmY, fmZ; acc.enable(); printf("\r\n\nFXOS8700Q Who Am I= %X\r\n", acc.whoAmI()); while (true) { acc.getAxis(acc_data); mag.getAxis(mag_data); printf("FXOS8700Q ACC: X=%1.4f Y=%1.4f Z=%1.4f ", acc_data.x, acc_data.y, acc_data.z); printf(" MAG: X=%4.1f Y=%4.1f Z=%4.1f\r\n", mag_data.x, mag_data.y, mag_data.z); acc.getX(&faX); acc.getY(&faY); acc.getZ(&faZ); mag.getX(&fmX); mag.getY(&fmY); mag.getZ(&fmZ); printf("FXOS8700Q ACC: X=%1.4f Y=%1.4f Z=%1.4f ", faX, faY, faZ); printf(" MAG: X=%4.1f Y=%4.1f Z=%4.1f\r\n", fmX, fmY, fmZ); wait(1.0); } }
