Hello! I am currently working on STM32F205 using Keil uvision. I have been getting an INVPC hard fault repeatedly. So I increased the stack size from 0x400 to 0x800 and set the stack alignment bit in CCR register at power on. This removed the INVPC hard

fault but instead I got Precise Bus Fault with following stack frame :R0 = 28000134 R1 = 1 R2 = 40000000 R3 = 1 R12 = ae60cd5 LR = 80015b9 PC = 80015be PSR = 2100002c- FSR/FAR: CFSR = 8200 HFSR = 40000000 DFSR = 0 AFSR = 0 BFAR = 28000130By disassemb...

I am getting the wrong values while interfacing MPU6050 Accelerometer with STM32F446RE. For Example for value of X, Y, Z axis as 0 , 0, 1 i am getting 0, 3.16, 1 for 0 ,1, 0 i am getting 3.16, 3.16, 0 and so on i am continuously getting this 3.16.

For MPU6050 i am using accelerometer range of +/-2g with sensitivity of 16384.For STM32F446RE board i am using I2C1 to interface with MPU6050 in standard mode with duty cycle as 50%. i am using PB6 as SCL and PB7 as SDA.Help me in getting my values i...
