Firmware migration using the library

The main changes in the source code/procedure in STM32F0 series versus STM32F1 are

described below:



Dual Clock Source (Refer to RCC section for more details).



No Prescaler feature configuration.



It supports more than one address (multiple addressing).



Each event flag has an associate enable control bit to generate the adequate interrupt.



In the CEC structure definition, seven fields should be initialized.

The example below shows how to configure the CEC STM32F1 series:

/* Configure the CEC peripheral */

CEC_InitStructure.CEC_BitTimingMode = CEC_BitTimingStdMode;

CEC_InitStructure.CEC_BitPeriodMode = CEC_BitPeriodStdMode;

CEC_Init(&CEC_InitStructure);

In STM32F0 series, you have to update this code as follows:

/* Configure CEC */

CEC_InitStructure.CEC_SignalFreeTime = CEC_SignalFreeTime_Standard;

CEC_InitStructure.CEC_RxTolerance = CEC_RxTolerance_Standard;

CEC_InitStructure.CEC_StopReception = CEC_StopReception_Off;

CEC_InitStructure.CEC_BitRisingError = CEC_BitRisingError_Off;

CEC_InitStructure.CEC_LongBitPeriodError = CEC_LongBitPeriodError_Off;

CEC_InitStructure.CEC_BRDNoGen = CEC_BRDNoGen_Off;

CEC_InitStructure.CEC_SFTOption = CEC_SFTOption_Off;

CEC_Init(&CEC_InitStructure);
