In this presentation, we will look at what the Serial Peripheral Interface, otherwise known as the SPI, is. and how it is used to communicate data to and from the PICmicro microcontroller.SPl is frequently used when few 1/O lines are available, but communication between two or more devices must be fast and easy to implement.In this presentation, we will discuss the following topics: We will first cover an Overview of SPI This section of the tutorial will introduce you to SPI and its concepts.Next, we will examine the use of SPI on the PICmicro MCU.The details of how SPI is implemented on a PICmicro device will be examined.Then, a Code Walkthrough will be given.The walkthough will explore code for both an SPI Master and SPI Slave. The example will have the Master generate data for sending to the slave.Finally, there will be a few resources given at the end of the presentation. These resources will allow you to explore in more detail the SPI interface

Simulation can provide a lot of information about what the system is doing. We canadd the effect of different element, like Encoder resolution, ADC sampling rate, etc and understand how does it affect the system. Another benefit is the possibility to slow down the process, to gain insight on what happens of fast systems or, vice versa, speed up slow process.Because National Instruments is a unique company in the fact the we provide a fullhardware solution couple with a full development platform, we can use this tools in very particular ways For example, it is possible to combine the LabVIEW Control Design and Simulation Module along with the FPGA module to quickly prototype a controller. One of the main benefits of this approach is that there is no need to compile the FPGA code, which allows for a quick algorithm design turnaround and debugging.

VME has been the de-facto bus standard for Commercial off the Shelf(COTS ) Circuit Card Assemblies since the 1980's. VME boards have proven to be remarkably capable of evolving to support newer technologies with innovations such as VME Subsystem Bus, PCI Mezzanine Cards(PMC's) and VME320.However, advances in technologies, appearing particularly in interconnects, have demonstratedthe need for an advance in system development. This advance needs to accommodate high speed interconnect, particularly serial interconnects, and higher power delivery in concert with better heat removal.

Finite state machines are widely used in digital circuit designs. Generally, when designing a state machine using an HDL, the synthesis tools will optimize away all states that cannot be reached and generate a highly optimized circuit. Sometimes, however, the optimization is not acceptable. For example, if the circuit powers up in an invalid state, or the circuit is in an extreme working environment and a glitch sends it into an undesired state, the circuit may never get back to its normal operating condition.
