Part Number:MSP430F5438A
Hello,
I'm working on a project in which there is an inter-board I2C link between the master MSP430F5438A and the slave STM32F207IG. Now whenever the master MSP430 resets(due to the external watchdog), the PE bit (Peripheral Enable bit) present in the I2C control register of STM32F2 is set to zero. This reset of the PE bit causes a deinitialisation of the I2C link. I'm also running Micrium 3 OS on MSP430. The PE bit does not reset when Micrium is not running on MSP, the reset occurs only when Micrium runs on MSP.Any idea why the PE bit changes? Is it possible that the RTOS is a cause for the reseting of the PE bit? If yes HOW?
