Debouncing Circuits

Pushbuttons are an inherent source of problems inside of sensitive circuits. Ideally, we like to think that when a button is pressed it is either “pressed” or “not pressed” without any sort of funny business. Unfortunately, as pushbuttons are a mechanical component, a lack of funny business simply isn’t going to be the case.

Getting Started with Xilinx Vivado and the Nexys 4

We’ve posted plenty of projects before that make use of Vivado. But how do you begin using it? This Instructable provides a guide to getting started with using Xilinx’s Vivado CAD with the Digilent Nexys 4. Alex uses Verilog to create the logic design. The Digilent Intro to Verilog Project provides an introduction to logic design.

I2C in LabVIEW

I recently published an Instructable on how to use I2C in LabVIEW using LabVIEW MakerHub LINX, chipKIT WF32, and PmodGYRO as an example. Digilent sells a both LabVIEW Home Bundle and chipKIT WF32 in the LabVIEW Physical Computing Kit. In this Instructable, I go over how to read the data sheet to find what you’re looking for and how exactly to code what you find. This guide also details how to set up pull-up resistors for successful I2C communication.

Instruction Pipelines

Implementation of an instruction pipeline is a common technique used when working with microprocessors. Pipelining improves operation and processing time. Microprocessors such as the Microchip® PIC32MX460F512L on the chipKIT Pro MX4 board use this technology to provide efficient processing and instruction execution. Though the process is sophisticated, it is actually quite simple in concept. In my explanation of instruction pipelines, I’ll specifically refer to the Microchip PIC32 microprocessor.

Coding Logic Gates

Earlier today, Josh (a fellow intern and blog contributor) wrote a blog post about logic gates. After reading through Josh’s post and gaining an understanding of the concepts and basic functions of those gates, I figured now would be the perfect time to learn some code. I am going to go over each logic gate and it’s code in Verilog (a hardware language), VHDL (another hardware language) and C (software language).
