Oscilloscope Xminilab-B Based on the Microcontroller Atmel AVR ATXMEGA32A4 ~ ELECTRONICS SOLUTION

This is an Oscilloscope Xminilab-B on the microcontroller Atmel AVR ATXMEGA32A4 electro suite. As we found in rlocman.ru, The Gabotronis company produces debug board to explore the possibilities of the family of microcontrollers Atmel XMEGA, which is a comprehensive mixed-signal oscilloscope and spectrum analyzer with arbitrary waveform generator. Additionally, there are two digital channels for using the device as a logic analyzer.

Distinctive features of the device:
For data visualization, user interface and organizing the control menu uses a graphical LCD display with a resolution of 128 × 128 pixels. All electronic components and controls are placed on double-sided printed circuit board.
