Recover from and remove the bus lock-up condition.Prevent a bus-lockup from hanging your system. ![]() This article discusses techniques that you can use to try and make your system more fault-tolerant and attempt to recover from any errors. If you are trying to operate a remote or embedded system, this is not ideal. Also, be sure to consult the STM HAL API documentation for detailed information on the available functions and their usage.It’s not unheard of for the i2c bus to “lock-up” on you, which can stop your system from working. Note that this is just a simple example, and your code may require additional modifications to work properly with the STM HAL API. Here's an example of what the converted code might look like: #include "stm32f4xx_hal.h" For example, you may need to change the data types or the way the code handles interrupts.
