µ[micro]electronics info

A weblog focused on interesting circuits, ideas, schematics and other information about microelectronics and microcontrollers.




Because I have not tested all electronic circuits mentioned on this pages, I cannot attest to their accuracy; therefore, I do not provide a warranty of any kind and cannot be held responsible in any manner.

Scopey II

Build a dsPIC Oscilloscope and Spectrum Analyzer with 128x64 LCD display

The ’scope can sample an input at up to 750,000 samples per second allowing for signals up to 375kHz to be viewed (sort of). The RMS value of the input is displayed on the main Oscilloscope screen. The FFT function separates the input into 128 frequency bins, and displays the frequency of the bin with the highest amplitude.
