PIC18F2550 KS0108 Graphical LCD Oscilloscope

This is the seventh part of an ongoing series about building a low-cost, open-source streaming internet radio. If you have not already, check out the previous parts for some background about the project. In part six, UNIX-style shell commands...

This circuit allows the simultaneous display of four signals using only one channel of an oscilloscope. It sequentially switches each input to the output while performing some signal conditioning. This configuration is designed for low-frequency signal measurements and lacks...

This article continues the AT90S4433 Microcontroller series. It is recommended to read the previous articles on Atmel Microcontroller programming. This time, a frequency counter is designed to measure frequencies from 1Hz to 100MHz. Alternatively, it can be used to...

This document outlines the connection of a 16x2 LCD display to a microcontroller, specifically the PIC 16F877A. The circuit diagram is provided, although power supply and oscillator connections for both the PIC and LCD are not depicted. The LCD...

This simple adapter utilizes an oscillator (567) to drive a counter (U2) and a switch (U3) that selects the output of one of four scope preamps (Q1/Q2 through Q7/Q8) and feeds it to buffer Q9 and output jack J1....

There are two primary types of backlights for LCDs: LEDs, which stands for light-emitting diodes, and EL, which stands for electroluminescent. EL backlights are generally more efficient and provide more uniform lighting compared to LED backlights, but they require...
