Field Detail

MAX_BYTES_PER_BIAS

public static final int MAX_BYTES_PER_BIAS

max number of bytes used for each bias. For 24-bit biasgen, only 3 bytes are used, but we oversize considerably for the future.

Constant Field Values

Constructor Detail

CypressFX2Biasgen

protected CypressFX2Biasgen(int devNumber)

Autogenerated proxy constructor.

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

sends the ipot values.

Specified by:

sendConfiguration in interface BiasgenHardwareInterface

Parameters:

biasgen - the biasgen which has the values to send

Throws:

HardwareInterfaceException

sendBiasBytes

protected void sendBiasBytes(byte[] b)
                      throws HardwareInterfaceException

Sends bytes with vendor request that signals these are bias values. These are sent as control transfers which have a maximum data packet size of 64 bytes. If there are more than 64 bytes worth of bias data, then the transfer must be (and is automatically) split up into several control transfers and the bias values can only be latched on-chip when all of the bytes have been sent.

Parameters:

b - bias bytes to clock out SPI interface

Throws:

HardwareInterfaceException

CypressFX2.VENDOR_REQUEST_SEND_BIAS_BYTES

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)

This implementation treats the biasgen as a simple array of IPots each of which provides bytes to send. Subclasses can override formatConfigurationBytes in case they have additional information to format. If the biasgen potArray is an IPotArray, the bytes are formatted and sent. Otherwise nothing is sent.

Specified by:

formatConfigurationBytes in interface BiasgenHardwareInterface

Parameters:

biasgen - the source of configuration information.

Returns:

the bytes to send
