Gray Code Basics

Gray Code Basics

Gray Codes are used in encoders, altimeters, and Karnaugh maps due to their error detection and unit-distant properties.


Make a PWM Driver for FPGA and SoC Design Using Verilog HDL

Make a PWM Driver for FPGA and SoC Design Using Verilog HDL

An FPGA is a crucial tool for many DSP and embedded systems engineers. However, the learning curve when getting started can be fairly steep. This project introduces the Quartus II and ModelSim software suites as well as a background on FPGA design flow for system on chip development. The development board used was a Terasic DE1-SoC, which has the Altera Cyclone V SoC chip. This IC contains an FPGA and an integrated ARM Cortex A9 as a hard processor system.

Design Your Own Controller for a Solder Reflow Oven

Design Your Own Controller for a Solder Reflow Oven

In the last installment, we built the hardware to control an AC waveform with a TRIAC as the first step in a DIY solder reflow oven. This tutorial continues the project by showing you how to set up the low-level hardware to measure temperature, read the zero-cross detector, drive the TRIAC, and print to the serial terminal using a USART.
