So this tutorial should show you how to get an analog input using a PIC microcontroller (I’m using a PIC16f887) in assembly language. You may have a demo board (which makes programming way easier) just a chip. I’m using just a plain 40 pin chip on a breadboard. Step 1: Hardware Setup -You will need […]

Microcontrollers are purely digital devices which work on logic0 and logic1 voltages; still they are widely used for analog signal processing. There are specialized signal processors chips available which are custom made for particular applications; however a general purpose microcontroller is more than enough for small kind of signal processing applications like audio signal input

The previous activities showed you how to make the microcontroller activate outputs. This activity demonstrates how to receive inputs from externally connected devices. The input programs also introduce the concept of abstraction—the ability of a program to refer to I/O circuits using assigned variable names rather than their specific hardware addresses. What you should know

Description Today we will learn how to read digital inputs from a push button switch. A digital input has only two values: 1 and 0. The configuration of the push button switch is same as that of the reset switch except it goes to a different port pin. The status of the switch will be
