Crate ni_fpga_interface

This crate provides an interface to NI FPGA devices.

It requires the use of a build script from the C interface in the linked ni-fpga-interface-build crate.

This module has two conceptual levels:

• session::Session - This is the main wrapper for the NI FPGA C interface. Some elements will be used directly but some will be easier to use in the higher level.
• The other modules define FPGA resources and can be used with session as a higher level interface. These include:
  • registers - For reading and writing registers i.e. front panel controls and indicators.
  • fifos - For reading and writing DMA FIFOs.
  • irq - For waiting on and acknowledging IRQs.

Registers and FIFOs are dynamic according to the particular bitfile you load. For this reason, the build module generates a module with the definitions of the registers and FIFOs for you.

Modules

• fifos
  Provides the high level interface for DMA FIFOs.
• irq
  The IRQ module implements handling for interrupts to and from the FPGA.
• registers
  Implements the register interfaces to the FPGA.
• session
  Holds session management functions for the FPGA.
