Function Documentation

u32 mip_sdk_get_time_ms

(

)

DESCRIPTION

Target-Specific Call to get the current time in milliseconds.

DETAILS

Parameters:

[in]

void

*port_handle - target-specific port handle pointer (user needs to allocate memory for this)

Returns:

Current time in milliseconds.

NOTES

1) This value should no roll-over in short periods of time (e.g. minutes)
2) Most systems have a millisecond counter that rolls-over every 32 bits
(e.g. 49.71 days roll-over period, with 1 millisecond LSB)
3) An absolute reference is not required since this function is
used for relative time-outs.
4) The user should copy the mip_sdk_user_functions.c file to their project directory and
edit it as needed to support their target operating system.

u16 mip_sdk_port_close

(

void *

port_handle

)

DESCRIPTION

Target-Specific port close function

DETAILS

Parameters:

[in]

void

*port_handle - target-specific port handle pointer (user needs to allocate memory for this)

Return values:

MIP_USER_FUNCTION_ERROR	When there is a problem closing the port.
MIP_USER_FUNCTION_OK	The close was successful.

NOTES

The user should copy the mip_sdk_user_functions.c file to their project directory and
edit it as needed to support their target operating system.

u16 mip_sdk_port_open	(	void **	port_handle,
		int	port_num,
		int	baudrate
	)

DESCRIPTION

Target-Specific communications port open.

DETAILS

Parameters:

[out]	void	*port_handle - target-specific port handle pointer (user needs to allocate memory for this)
[in]	int	port_num - port number (as recognized by the operating system.)
[in]	int	baudrate - baudrate of the com port.

Return values:

MIP_USER_FUNCTION_ERROR	When there is a problem opening the port.
MIP_USER_FUNCTION_OK	The open was successful.

NOTES

The user should copy the mip_sdk_user_functions.c file to their project directory and
edit it as needed to support their target operating system.

u16 mip_sdk_port_read	(	void *	port_handle,
		u8 *	buffer,
		u32	num_bytes,
		u32 *	bytes_read,
		u32	timeout_ms
	)

DESCRIPTION

Target-Specific Port Write Function.

DETAILS

Parameters:

[in]	void	*port_handle - target-specific port handle pointer (user needs to allocate memory for this)
[in]	u8	*buffer - buffer containing num_bytes of data
[in]	u32	num_bytes - the number of bytes to write to the port
[out]	u32	*bytes_read - the number of bytes actually read from the device
[in]	u32	timeout_ms - the read timeout

Return values:

MIP_USER_FUNCTION_ERROR	When there is a problem communicating with the port.
MIP_USER_FUNCTION_OK	The read was successful.

NOTES

The user should copy the mip_sdk_user_functions.c file to their project directory and
edit it as needed to support their target operating system.

u32 mip_sdk_port_read_count

(

void *

port_handle

)

DESCRIPTION

Target-Specific Function to Get the Number of Bytes Waiting on the Port.

DETAILS

Parameters:

[in]

void

*port_handle - target-specific port handle pointer (user needs to allocate memory for this)

Returns:

Number of bytes waiting on the port,
0, if there is an error.

NOTES

The user should copy the mip_sdk_user_functions.c file to their project directory and
edit it as needed to support their target operating system.

u16 mip_sdk_port_write	(	void *	port_handle,
		u8 *	buffer,
		u32	num_bytes,
		u32 *	bytes_written,
		u32	timeout_ms
	)

DESCRIPTION

Target-Specific Port Write Function.

DETAILS

Parameters:

[in]	void	*port_handle - target-specific port handle pointer (user needs to allocate memory for this)
[in]	u8	*buffer - buffer containing num_bytes of data
[in]	u32	num_bytes - the number of bytes to write to the port
[out]	u32	*bytes_written - the number of bytes actually written to the port
[in]	u32	timeout_ms - the write timeout

Return values:

MIP_USER_FUNCTION_ERROR	When there is a problem communicating with the port.
MIP_USER_FUNCTION_OK	The write was successful.

NOTES

The user should copy the mip_sdk_user_functions.c file to their project directory and
edit it as needed to support their target operating system.
