Arduino Quick Start
M5Fire IMU attitude sensor input related APIs and example program.
#include <M5Unified.h> void setup(void) { auto cfg = M5.config(); M5.begin(cfg); M5.Display.setTextFont(&fonts::Font4); M5.Display.setTextSize(1);} void loop(void) { auto imu_update = M5.Imu.update(); if (imu_update) { M5.Display.setCursor(0, 24); M5.Display.clear(); // Delay 100ms auto ImuData = M5.Imu.getImuData(); // The ImuData obtained by getImuData can be used as follows. ImuData.accel.x; // accel x-axis value. ImuData.accel.y; // accel y-axis value. ImuData.accel.z; // accel z-axis value. ImuData.accel.value; // accel 3values array [0]=x / [1]=y / [2]=z. ImuData.gyro.x; // gyro x-axis value. ImuData.gyro.y; // gyro y-axis value. ImuData.gyro.z; // gyro z-axis value. ImuData.gyro.value; // gyro 3values array [0]=x / [1]=y / [2]=z. M5.Display.printf("IMU:\r\n"); M5.Display.printf("ax:%6.2f ay:%6.2f az:%6.2f\r\n", ImuData.accel.x, ImuData.accel.y, ImuData.accel.z); M5.Display.printf("gx:%6.2f gy:%6.2f gz:%6.2f\r\n", ImuData.gyro.x, ImuData.gyro.y, ImuData.gyro.z); } delay(100);}
This program will display the axis information of attitude sensor on the screen.
Fire IMU part uses the IMU_Class
