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