Firmware migration using the library

Note:

(*) These functions exist only on STM32F10X_LD_VL, STM32F10X_MD_VL, and

STM32F10X_HD_VL devices.

(**)This function is only applicable for STM32F072 and STM32F091 devices.

The main changes in the source code/procedure in STM32F051 devices versus STM32F1

are described below:



No Dual mode for DAC channels



No Noise generator



No Triangle generator



In the DAC structure definition, only two fields (external trigger, OutputBuffer) should be

initialized.

The example below shows how to configure the DAC channel 1 STM32F1 series:

/* DAC channel1 Configuration */

DAC_InitStructure.DAC_Trigger = DAC_Trigger_None;

DAC_InitStructure.DAC_WaveGeneration = DAC_WaveGeneration_None;

DAC_InitStructure.DAC_OutputBuffer = DAC_OutputBuffer_Enable;

DAC_Init(DAC_Channel_1, &DAC_InitStructure);

Only for STM32F051devices, you have to update this code as follows:

/* DAC channel1 Configuration */

DAC_InitStructure.DAC_Trigger = DAC_Trigger_None;

DAC_InitStructure.DAC_OutputBuffer = DAC_OutputBuffer_Enable;

/* DAC Channel1 Init */

DAC_Init(DAC_Channel_1, &DAC_InitStructure);

void DAC_DMACmd(uint32_t DAC_Channel,

void DAC_ITConfig(uint32_t DAC_Channel,

uint32_t DAC_IT, FunctionalState NewState);(*)

void DAC_ITConfig(uint32_t DAC_Channel,

uint32_t DAC_IT, FunctionalState NewState);

FlagStatus DAC_GetFlagStatus(uint32_t

DAC_Channel, uint32_t DAC_FLAG);(*)

FlagStatus DAC_GetFlagStatus(uint32_t

DAC_Channel, uint32_t DAC_FLAG);

void DAC_ClearFlag(uint32_t DAC_Channel,

uint32_t DAC_FLAG);(*)

void DAC_ClearFlag(uint32_t DAC_Channel,

uint32_t DAC_FLAG);

ITStatus DAC_GetITStatus(uint32_t

DAC_Channel, uint32_t DAC_IT);(*)

ITStatus DAC_GetITStatus(uint32_t

DAC_Channel, uint32_t DAC_IT);

void DAC_ClearITPendingBit(uint32_t

DAC_Channel, uint32_t DAC_IT);(*)

void DAC_ClearITPendingBit(uint32_t

DAC_Channel, uint32_t DAC_IT);
