The objective is to set up SPI communication between VTI Technologies digital pressure sensor component and an MCU of an application device ATMEGA16L. In this code example: ?The MCU is configured ?SCP1000-D01 is initialized and configured ?The high resolution measurement mode is activated ?Temperature and pressure information is read always when the DRDY pin is in high state Please refer to the document "SCP1000 Product Family Specification 8260800" for further information on SCP1000 register addressing and SPI communication. This document applies to the SCP1000-D01.

The FPGA can realize a more optimized Digital controller in DC/DC Converters when compare to DSPs. In this paper, based on the FPGA platform, The theoretical analysis, characteristics, simulation and design consideration are given. The methods to implement the digital DC/DC Converters have been researched. The function module, state machine of digital DC/DC controller and high resolution DPWM with Sigma- Delta dither has been introduced. They are verified by experiments on a 20 W, 300 KHz non-isolated synchronous buck converters.

RS_latch using vhdl, When using static gates as building blocks, the most fundamental latch is the simple SR latch, where S and R stand for set and reset. It can be constructed from a pair of cross-coupled NOR (Not OR) logic gates. The stored bit is present on the output marked Q. Normally, in storage mode, the S and R inputs are both low, and feedback maintains the Q and Q outputs in a constant state, with Q the complement of Q. If S (Set) is pulsed high while R is held low, then the Q output is forced high, and stays high when S returns to low similarly, if R (Reset) is pulsed high while S is held low, then the Q output is forced low, and stays low when R returns to low.

This paper describes a bus mastering implementation of the PCI Express protocol using a Xilinx FPGA. While the theoretical peak performance of PCI Express is quite high, attaining that performance is a complex endeavor on top of an already complex protocol. The implementation is described and its performance is analyzed. Source code is offered for free download via the web.
