About a month\u00a0ago we released the Digital Discovery<\/a> with the early adopter promo.<\/p>\n

The Digital Discovery, High Speed Adapter, and 4 High Speed logic probes. Turning 4 pins into high speed inputs.<\/figcaption><\/figure>\n

As I’ve watched those go out the door I’ve been eagerly awaiting feedback from customers and they begin to use their Digital Discoverys<\/a>. One of the first I’ve seen is Steve Liebson from Xilinx who gave his take on the hands-on experience with the Digital Discovery<\/a>. As a comparison he begins by recounting his first experience with a Logic Analyzer,\u00a0the HP 1615A.<\/p>\n

\"\"<\/p>\n

Well, it\u2019s exactly 40 years later and see what time, Digilent, and Xilinx FPGA technology have wrought. Digilent\u2019s $199.99 Digital Discovery provides the same number of logic-analysis channels as the $6800 HP 1615A but runs 10x to 40x faster and has a 2Gbit acquisition buffer. (The HP 1615A had a 6Kbit acquisition buffer, but that was 40 years ago.) In addition, the Digilent Digital Discovery can not only display digital signals, it can decode and trigger on commonly used serial-bus protocols including SPI, I\u00b2C, UART, I2S, and CAN. Of course, none of those even existed 40 years ago except for the UART NRZ protocol.<\/p><\/blockquote>\n

Next he goes over one of the most important factors (in my opinion) of any new tool… Is it easy to use? He recounts the installation process commenting that:<\/p>\n

By the way, I did all of this without taking a peek at the manual.<\/p><\/blockquote>\n

Then he connected up the Digital Discovery to the Motor Control Shield’s I2C pins to decode the data, and viewed the PWM signal driving the servo. He provided a short video showing the signals.<\/p>\n

\"\"
Some of the captured I2C data.<\/figcaption><\/figure>\n

Summarizing the experience, he recanted:<\/p>\n

Again, setting up the Digital Discovery to capture this waveform is pretty simple, pretty intuitive.<\/p><\/blockquote>\n

To read his whole experience, check out this post on the xilinx forum.<\/a><\/p>\n

If\u00a0you are reading this, but\u00a0need help with your Digital Discovery<\/a>, make sure to take a peek at the Getting Started Guide<\/a> and tutorials on our Wiki<\/a>, and post on the Forum<\/a>\u00a0if you have any questions. I look forward to seeing more experiences and projects.\u00a0Comment below with your experience with the Digital DIscovery.<\/p>\n
