Detailed Description

Enumeration Type Documentation

enum oC_SaiPll_OutputLine_t

The type is for storing SAI PLL output line (look to the STM32F7 documentation for a CLOCK TREE)

Enumerator
oC_SaiPll_OutputLine_LTDC	Output of the PLL connected to the LTDC module (LTDC Clock)
oC_SaiPll_OutputLine_PLL48CLK	Output of the PLL connected to the PLL48CLK.
oC_SaiPll_OutputLine_SAICLK	Output of the PLL connected to the SAI.
oC_SaiPll_OutputLine_NumberOfElements	Number of main elements (maximum index) in the type. All lines that has number smaller than this value can be configured separately
oC_SaiPll_OutputLine_IndexMask	This is the mask to get index of the line from the type.
oC_SaiPll_OutputLine_SAI1CLK	Additional definition for SAI1 CLK line. It has the same index as SAICLK, because it cannot be configured to the different frequency than SAI2
oC_SaiPll_OutputLine_SAI2CLK	Additional definition for SAI2 CLK line. It has the same index as SAICLK, because it cannot be configured to the different frequency than SAI1
oC_SaiPll_OutputLine_LTDC	Output of the PLL connected to the LTDC module (LTDC Clock)
oC_SaiPll_OutputLine_PLL48CLK	Output of the PLL connected to the PLL48CLK.
oC_SaiPll_OutputLine_SAICLK	Output of the PLL connected to the SAI.
oC_SaiPll_OutputLine_NumberOfElements	Number of main elements (maximum index) in the type. All lines that has number smaller than this value can be configured separately
oC_SaiPll_OutputLine_IndexMask	This is the mask to get index of the line from the type.
oC_SaiPll_OutputLine_SAI1CLK	Additional definition for SAI1 CLK line. It has the same index as SAICLK, because it cannot be configured to the different frequency than SAI2
oC_SaiPll_OutputLine_SAI2CLK	Additional definition for SAI2 CLK line. It has the same index as SAICLK, because it cannot be configured to the different frequency than SAI1

Function Documentation

oC_ErrorCode_t oC_SaiPll_Configure	(	oC_SaiPll_OutputLine_t	OutputLine,
		oC_Frequency_t	Frequency,
		oC_Frequency_t	PermissibleDifference,
		oC_Frequency_t *	outRealFrequency
	)

The function configures and reconfigures PLLSAI. It tries to keep old setting if some of output line is already used.

Parameters

OutputLine	Type of the output line that you want to configure (other lines will not be changed)
Frequency	Wanted frequency to configure
PermissibleDifference	Maximum difference between real frequency and wanted frequency
outRealFrequency	Output frequency that has been configured

Returns

code of error or oC_ErrorCode_None if success
