Serial Output does not work about 9dof_razor_imu

[bboyho]

Hi,

By default, the data is sent through the USB to the serial monitor by default. If you are trying to send the data through the hardware UART pins (labeled as pins 00|RX and 01|TX), you should be able to receive data on the other device. Just redefine the port for Serial1 on this line

9DOF_Razor_IMU/Firmware/_9DoF_Razor_M0_Firmware/config.h

Line 25 in 6df2dc2

#define LOG_PORT SERIAL_PORT_USBVIRTUAL

as

#define LOG_PORT SERIAL_PORT_HARDWARE

I am not sure why the IMU would fail by just connecting to the hardware UART pins on this line:

9DOF_Razor_IMU/Firmware/_9DoF_Razor_M0_Firmware/_9DoF_Razor_M0_Firmware.ino

Line 148 in 2865253

if ( imu.dmpUpdateFifo() != INV_SUCCESS )

Without further information your case, all I can do is recommend that you make sure to check your connections and ensure that your device is not sending random data to the IMU.
