Detailed Description

Dio Specific Arquitecture Driver

Author

Diego Perez

Dio driver implementation for the STM32G0xx family of microcontrollers. This file contains the hardware specific implementation of the Dio driver. The file is implemented as a means of abstraction from the hardware, this way we can avoid to include Arch headers in the actual driver header, making the low level interfaces available only for the inmediate upper layer.

Function Documentation

Dio_Arch_FlipChannel()

Dio_LevelType Dio_Arch_FlipChannel	(	Dio_PortType	Port,
		uint8	Pin )

Flip Channel.

This function will flip the level of the specified channel writting the opposite value in the register ODR speficied by parameter Pin. from the port specified by the parameter Port. the fucntion will also return the level of the channel after flipping it reading the value from the register IDR.

Parameters

Port	Port ID.
Pin	Pin ID.

Return values

Returns

the level of a channel after flipping the level.

Requirement

SWS_Dio_00191, SWS_Dio_00192, SWS_Dio_00193

< Offset to set the bit in BSRR register

Dio_Arch_MaskedWritePort()

void Dio_Arch_MaskedWritePort	(	Dio_PortType	Port,
		Dio_PortLevelType	Level,
		Dio_PortLevelType	Mask )

Masked Write Port.

This function will set the specified value for the channels on the specified port if the corresponding bit in Mask is '1'.

Parameters

Port	ID of DIO Port.
Level	Value to be written.
Mask	Channels to be masked in the port.

Requirement

SWS_Dio_00202, SWS_Dio_00203, SWS_Dio_00204

Dio_Arch_ReadChannel()

Dio_LevelType Dio_Arch_ReadChannel	(	Dio_PortType	Port,
		uint8	Pin )

Read Channel.

The function will return the bit from register IDR speficied by paramter Pin. from the port specified by the parameter Port.

Parameters

Port	Port ID.
Pin	Pin ID.

Return values

Returns

the value of the specified DIO channel.

Requirement

SWS_Dio_00027, SWS_Dio_00074

Dio_Arch_ReadChannelGroup()

Dio_PortLevelType Dio_Arch_ReadChannelGroup

(

const Dio_ChannelGroupType *

ChannelGroupIdPtr

)

Read Channel Group.

This function will read a subset of the contiguous bits of register IDR of a port (channel group). The function will not change the remaining channels of the port or the channels

Parameters

ChannelGroupIdPtr

Pointer to ChannelGroup.

Return values

Returns

the level of a subset of the adjacent bits of a port (channel group).

Requirement

SWS_Dio_00037, SWS_Dio_00092, SWS_Dio_00093, SWS_Dio_00114

Dio_Arch_ReadPort()

Dio_PortLevelType Dio_Arch_ReadPort

(

Dio_PortType

Port

)

Read Port.

The function will return the level of all pins of the port specified by the parameter Port. The function will read the value from the register IDR.

Parameters

Port	ID of DIO Port.

Return values

Returns

the level of all channels on that port.

Requirement

SWS_Dio_00031, SWS_Dio_00104, SWS_Dio_00075

Dio_Arch_WriteChannel()

void Dio_Arch_WriteChannel	(	Dio_PortType	Port,
		uint8	Pin,
		Dio_LevelType	Level )

Write Channel.

This function will write the specified value to register ODR speficied by parameter Pin. from the port specified by the parameter Port.

Parameters

Port	Port ID.
Pin	Pin ID.
Level	Value to be written.

Requirement

SWS_Dio_00028, SWS_Dio_00029, SWS_Dio_00079

Dio_Arch_WriteChannelGroup()

void Dio_Arch_WriteChannelGroup	(	const Dio_ChannelGroupType *	ChannelGroupIdPtr,
		Dio_PortLevelType	Level )

Write Channel Group.

This function will set a subset of the adjacent bits of a port (channel group) writting the specified value to the register ODR. The function will not change the remaining channels of the port or the channels

Parameters

ChannelGroupIdPtr	Pointer to ChannelGroup.
Level	Value to be written.

Requirement

SWS_Dio_00039, SWS_Dio_00040, SWS_Dio_00090, SWS_Dio_00091

Dio_Arch_WritePort()

void Dio_Arch_WritePort	(	Dio_PortType	Port,
		Dio_PortLevelType	Level )

Write Port.

This function is used to write a value to all channels of the specified port. The function will write the value to the register ODR.

Parameters

Port	ID of DIO Port.
Level	Value to be written.

Requirement

SWS_Dio_00034, SWS_Dio_00035, SWS_Dio_00105, SWS_Dio_00108
