Method Detail

setPowerDown

public void setPowerDown(boolean powerDown)
                  throws HardwareInterfaceException

Description copied from interface: BiasgenHardwareInterface

sends the powerdown vendor request to power down the chip.

Typically this method toggles the powerDown pin correctly to ensure on-chip biasgen is powered up. Chip may have been plugged in without being powered up. If powerdown is true, simply sets powerdown high. If powerdown is false, powerdown is toggled high and then low, to make sure a nagative transistion occurs. This transistion is necessary to ensure the startup circuit starts up the masterbias again.

Specified by:

setPowerDown in interface BiasgenHardwareInterface

Parameters:

powerDown - true to power OFF the biasgen, false to power on

Throws:

HardwareInterfaceException

sendConfiguration

public void sendConfiguration(Biasgen biasgen)
                       throws HardwareInterfaceException

Description copied from interface: BiasgenHardwareInterface

Sends the configuration values to the hardware. The configuration can include bias values (both for on- and off-chip sources), configuration bits, etc.

Specified by:

sendConfiguration in interface BiasgenHardwareInterface

Parameters:

biasgen - the object that holds the configuration.

Throws:

HardwareInterfaceException

flashConfiguration

public void flashConfiguration(Biasgen biasgen)
                        throws HardwareInterfaceException

Description copied from interface: BiasgenHardwareInterface

flashes the configuration in non-volatile storage so they will be reloaded on reset or powerup.

Specified by:

flashConfiguration in interface BiasgenHardwareInterface

Parameters:

biasgen - holds the configuration values

Throws:

HardwareInterfaceException

formatConfigurationBytes

public byte[] formatConfigurationBytes(Biasgen biasgen)

Description copied from interface: BiasgenHardwareInterface

Formats and returns the bytes that should be sent to set a particular configuration.

Specified by:

formatConfigurationBytes in interface BiasgenHardwareInterface

Parameters:

biasgen - the source of the configuration.

Returns:

the array to be sent.

startAEReader

public void startAEReader()
                   throws HardwareInterfaceException

Starts reader buffer pool thread and enables in endpoints for AEs. This method is overridden to construct our own reader with its translateEvents method

Overrides:

startAEReader in class CypressFX2MonitorSequencer

Throws:

HardwareInterfaceException
