Pulse Generation and Detection with Microcontroller Units (PDF 26p)

EBook Description: This application note examines two common interfaces between microcontroller units (MCUs) and external circuitry: � Pulse generation � Pulse detection

This note provides basic implementation details and procedural information to design and assemble a stepper motor system. The controller discussed here is the MC68HC11E9, an 8-bit Freescale microcontroller (MCU)

Controlling Stepper Motors with a PIC Microcontroller

For applications where precise measuring of a motors' rotor position is critical, a Stepper Motor is the best choice. Stepper motors operate differently from other motors; rather than voltage being applied and the rotor spinning smoothly, stepper motors turn on a series of electrical pulses to the motor's windings. Each pulse rotates the rotor by an exact degree.

Microcontroller Interfacing Techniques

Micro-controllers are useful to the extent that they communicate with other devices, such as sensors, motors, switches, keypads,displays, memory and even other micro-controllers.

Introduction to Microcontrollers (PDF 103p)

Even at a time when Intel presented the first microprocessor with the 4004 there was alrady a demand
for microcontrollers: The contemporary TMS1802 from Texas Instruments, designed for usage in calculators, was by the end of 1971 advertised for applications in cash registers, watches and measuring
instruments. The TMS 1000, which was introduced in 1974, already included RAM, ROM, and I/O on-chip and can be seen as one of the first microcontrollers, even though it was called a microcomputer.

Introduction to Microcontrollers version II (PDF 175p)

Apart from a few small controllers, most microcontrollers have integrated analog/digital
converters, which differ in the number of channels (2-16) and their resolution (8-12 bits). The
analog module also generally features an analog comparator. In some cases, the microcontroller
includes digital/analog converter

What is a Microcontroller (PDF 126p)

Most of us know what a computer looks like. It usually has a keyboard, monitor, CPU (Central Processing Unit), printer, and a
mouse. These types of computers, like the Mac or PC, are primarily designed to communicate (or �interface�) with humans.

Introduction to Microcontrollers Lecture Notes (PDF 134)

A microcontroller is essentially a microprocessor with several other features embedded onto a single chip.

What is a Microcontroller Student Guide (PDF 340p)

This text is organized so that it can be used by the widest possible variety of students as well as independent learners. Middle school students can try the examples in this text in a guided tour fashion by simply following the check-marked instructions and instructor supervision.

Microcontroller Interfacing Circuits (PDF 44p)

Explanations of BASIC commands are provided in the Commands section (available separately). The interfacing circuits can also be used with any PIC microcontrollers such as the PIC16F84, although these microcontrollers may require
programming in assembler code.

Microcontroller Usage (PDF 32p)

A microcontroller is a computer on a chip used to control electronic devices. It is a type of microprocessor emphasizing self-sufficiency and costeffectiveness, in contrast to a general-purpose microprocessor, the kind used in a PC.
