It’s been quite sometime since I’ve lasted posted and I thought I’d let everyone know that Mountain Storm Instruments is still alive and kicking. The reason for the long delay is that I’ve been down in the skunk works designing, building and testing two new systems. The older uCDAQ system is about to get replaced… Continue reading Still alive and kicking

FPGA based DAQ part 1: Introduction and Benefits
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
