Constructor Detail

DAC_MAX5500

public DAC_MAX5500()

Method Detail

init

public static void init()

Initialize the SPI on PSC6.

This method has to be called before using the SPI!

send

public static void send(int ch,
                        short val)

Sends a value over the SPI to one of the four DAC-channels. A call of this method is not blocking! A call to this method can be followed by another call to this method, as the data is written to a hardware fifo.

Parameters:

ch - channel of the DAC (0, 1, 2, 3)

val - value

setUPO

public static void setUPO(boolean val)

Sets the digital output pin on the DAC. A call of this method is not blocking! A call to this method can be followed by another call to this method, as the data is written to a hardware fifo.

Parameters:

val - value

availToWrite

public static int availToWrite()

Returns the number of free bytes available in the transmit fifo. It is possible, to send the returned number of bytes in one nonblocking transfer.

Returns:

the available free bytes in the transmit fifo.
