Hello, sorry for my bad English. I'm developing an application for a STM32F103ZE that reads the value from three sensor via I2C bus, use the SysTick timer, use USART1 to communicate with the pc, generates four ...

I can use only this type of sensor. The problem is the i2c bus that stucks with all kind of interrupt, also with USART interrupt. I think that the interrupt desinchronizes the mcu with the i2c slave and the mcu...
Posted on August 30, 2012 at 19:45I tried to deactive the ext interrupt before read the sensor data via I2C bus and to active it after the operation: the mcu doesn't stuck, but the measure of the pulse width with the external interrupt doesn't work ...

ok in debug mode I found the problem. The mcu stop the execution on this instruction:
while(!I2C_CheckEvent(MPU6050_I2C, I2C_EVENT_MASTER_TRANSMITTER_MODE_SELECTED)); that I use to communicate with the...
