Constructor & Destructor Documentation

tcDspFtdiVNC1::tcDspFtdiVNC1	(	tcDspSerial *	apSerialInterface,
		tcDspOutputLatch *	apLatch,
		unsigned int	apLatchID[4]
	)

This constructor is used to open an interface to a FTDI VNC1 device via the provided serial interface.

Parameters:

[in]	apSerialInterface	Pointer to the serial interface for the device.
[in]	apLatch	Pointer to an output latch controlling Chip Select.
[in]	apLatchID	Array of latch IDs to use for this device. apLatchID[0] is the reset pin apLatchID[1] is the tri state pin apLatchID[2] is the ACBUS5 pin for interface mode selection apLatchID[3] is the ACBUS6 pin for interface mode selection

Returns:: None.

Member Function Documentation

void tcDspFtdiVNC1::ReceiveDispatch ( Arg ftdiVNC1 )

static

Static dispatch for receive thread.

Parameters:

[in] ftdiVNC1 pointer to VNC1 object

Returns:: None.

See also:: DspFtdiVNC1.h

void tcDspFtdiVNC1::ResetDevice	(	tcDspOutputLatch *	apLatch,
		unsigned int	apLatchID[4]
	)

Reset the device.

Reset the FTDI VNC1 device using the provided latch and set its i/o mode to serial.

Parameters:

[in]	apLatch	Pointer to an output latch controlling Chip Select.
[in]	apLatchID	Array of latch IDs to use for this device. apLatchID[0] is the reset pin apLatchID[1] is the tri state pin apLatchID[2] is the ACBUS5 pin for interface mode selection apLatchID[3] is the ACBUS6 pin for interface mode selection

To reset the device, we do the following dance...

first set tri-state pin to normal
Set the interface mode pins to both low (to tell the chip to use serial mode). (The FTDI VNC1 chip only reads these pins at reset).
Toggle reset the line ( a small delay here to make sure the device resets (I couldn't find a spec'd value for reset time).
first set tri-state pin back to tri-state

void tcDspFtdiVNC1::Initialize	(	int	anBaud,
		int	anThreadPri
