I ran the code on a UNO (dont have Qduino or MPU9520) status returned is -1.
The register is the clock source to the gyro. It writes a value then reads it back, if it is not the same it returns with an error. Status return of -1 (as you have shown) is first read / write to the MPU9250. UNO Qdino differences, 16Hz clock 8MHz clock, Atmega328P Atmega32u4.ĮDIT: Further investigation. If you check these values it might give you a clue. Then there is a whole lot of if statements that return negative which is where your code is dropping out. The begin routine first intialises the SPI or I2C interfaces depending on which you are using. Dont know which MPU9250 library you are using, so I chose the first one in the list, Bolder Flight systems. Have looked at Sparkfun schematic and library on Github. The circuit is the same which looks like this. If (status IMU initialization unsuccessfulĢ3:38:13.187 -> Check IMU wiring or try cycling powerīut it runs well with arduino uno so i do not know what the problem is. an MPU9250 object with the MPU-9250 sensor on I2C bus 0 with address 0圆8 I am trying to measure the inclination angle. So what i want to do is to make the qduino read the code and display the inclination value. Hi there, I have some problem with the code at the moment.
