I can get the right WHO_I_AM(0x70) from mpu6500 by i2c,but I cant read other register or write other register.I cant read the gyroscope/accelerometer . whats more  ,i changed some mpu6500,and it doesnt work.

So what investigation / testing / debugging have you done to find what's wrong?

Which STM32? They make a handful these days..

Did you explicitly start the device? Most IMU need to be configured in a mode of operation and started.

Perhaps look at other examples of use, say GitHub for Flight Controller type code, etc.

Note that the MPU-6500 is not recommended for new designs:
