A quick introduction to FPGA based technology for building DAQ systems What is an FPGA based DAQ system ? There are many way to build up a DAQ (data acquisition system). The goal of a DAQ system is generally to take an electrical signal of some kind and convert it into digital data for further… Continue reading FPGA based DAQ part 1: Introduction and Benefits

DSP book list
Here’s some books I’ve found to have good practical value for people new to DSP: Understanding Digital Signal Processing (3rd Ed.), Richard G. Lyons, 2010, ISBN-10: 0137027419. An excellent book to help you apply DSP to real world problems. There are some nice explanations of the theory as well that makes for a good refresher… Continue reading DSP book list
GPS PPS use as a time reference
Most GPS modules today have an output called PPS. PPS stands for Pulse Per Second and is a digital output signal which changes value on the 1 sec. boundary for UTC (Universal Coordinated) time. This signal can be used to reset internal counters in a DAQ system that count the number of clock ticks from… Continue reading GPS PPS use as a time reference
Avnet Spartan 6 LX9 Microboard does not include EDK license needed for Microblaze tutorials
I bought this board because I am building a DAQ system based off some of the components on this board. I also wanted to build up some familiarity with the Xilinx EDK/SDK tool flow. The kit came with a Xilinx ISE s/w license for embedded development. However, I learned it was only for the software… Continue reading Avnet Spartan 6 LX9 Microboard does not include EDK license needed for Microblaze tutorials
