Hello,
I am trying to use the compdcm_mpu9150.c that comes in the ek-tm4c1294xl-boostxl-senshub folder (TivaWare_C_Series-2.1.2.111) with a MPU9250 instead of a MPU9150. I looked at the registers map of each module and they are almost the same, so I assumed I could use the project as it is without changing the libraries. I used 3.3k pull up resistors in the SDA/SCL lines (the Sensor Hub board does this when connecting it to J1&J2) and also connected AD0 to ground to set the module I2C address to 0x68. The problem is that I do not receive any data and the program stops working when reaching this line: MPU9150AppI2CWait(__FILE__, __LINE__);. Also the following error appears: Error 3 - I2CM_STATUS_ARB_LOST.
I want to know if it is possible to fix this problem and use the MPU9250 with these code,
Regards,
Joana
