Wireless Data Link

Photo 1: The robot measures a little over 4″. Designed for tele-operated
remote surveillance, it contains a video camera and transmitter. Scout
can hop over obstacles by hoisting its tail spring (shown extended) and
quickly releasing it to slap the ground and propel the robot into the air.

In 2001, while working on self-contained robot system called “Scout,” Tom Dahlin and Donald Krantz developed an interesting wireless data link. A tubular, wheeled robot, Scout’s wireless data link is divided into separate boards, one for radio control and another containing RF hardware. … Continue reading

USB-to-FPGA Communications: A Case Study of the ChipWhisperer-Lite

Photo 1: This shows the ChipWhisperer-Lite, which contains a Xilinx Spartan 6 LX9 FPGA and Atmel SAM3U2C microcontroller. The remaining circuitry involves the power supplies, ADC, analog processing, and a development device which the user programs with some cryptographic algorithm they are analyzing.

Sending data from a computer to an FPGA is often required. This might be FPGA configuration data, register settings, or streaming data. An easy solution is to use a USB-connected microcontroller instead of a dedicated interface chip, which allows you … Continue reading
