About the X5 XMC Modules

Use the baseboard

IdRom()

method to obtain a reference to the internally-managed

IUsesPmcEeprom

object, as shown

below:

// Open the module

Innovative::X5_400M Module;

Module.Target(0);

Module.Open();

// Create a 50-32-bit-word section at offset zero in ROM user space

PmcIdromSection Section1(Module.IdRom().Rom(), PmcIdrom::waUser, 0, 50);

// Create a 50-32-bit-word section at offset 50 in ROM user space

PmcIdromSection Section2(Module.IdRom().Rom(), PmcIdrom::waUser, 50, 50);

// Write to ROM

for (int i = 0; i < 50; ++i)

Section1.AsInt(i, i*2);

Section1.StoreToRom();

for (int i = 50; i < 100; ++i)

Section2.AsFloat(i, static_cast<float>(i*2));

Section2.StoreToRom();

// Read from ROM

Section1.LoadFromRom();

for (int i = 0; i < 50; ++i)

int x = Section1.AsInt(i);

Section2.LoadFromRom();

for (int i = 50; i < 100; ++i)

float x = Section2.AsFloat(i);

Digital

I/O

The X5 series has a digital I/O port accessible over the P16 connector that provides basic bit I/O. The port provides 16 bits of I/

O that may be used as inputs or outputs. The port is configured and accesses directly from the PCI Express host. For more

advanced applications, the digital I/O port may be reconfigured in custom logic applications for a variety purposes since it is

provides direct connections to the applicant FPGA. The port pins use 3.3V LVTTL signaling.
