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.
