Detailed Description

      Project: Petaluma (MAXREFDES30#)
     Filename: maximDeviceSpecificUtilities.c
  Description: This module uses the AXI_MAX11046 custom ip core Ver 1.00a to
               read ADC data from the Petaluma MAXREFDES30#.  These
               low level functions could be cut/pasted into the user's
               application as a starting point for development of an end
               application.

Function Documentation

void continuous_sampling ( int Channel )

Continuously reads the ADC and display the data via the HyperTerminal.

Details: This function reads the ADC every half of a second and display the data
via the Hyperterminal. Press the ESC key to return to the main menu.

Parameters

None

Return values

None

Definition at line 185 of file maximDeviceSpecificUtilities.c.

int SetupInterruptSystem ( XScuGic * IntcInstancePtr )

Setup the interrupt handler.

Details: This function connects the interrupt handler to the processor

Parameters

[in] *IntcInstancePtr - IntcInstancePtr is the instance of the interrupt controller

Return values

XST_SUCCESS to indicate success, otherwise XST_FAILURE

	)

Receive a block of samples at a constant rate.

Details: This function is used to receive a block of samples at a constant
sampling rate. The size of the block is defined in u16 *auSampleSize.
And the sampling rate is defined in int nSampleRate. The Sampled data
will be stored in an array *auSamples

Parameters
