Microcontrollers: Fundamentals and Applications with PIC

Microcontrollers exist in a wide selection of versions with various constructions and diverse software possibilities. regardless of this range, it really is attainable to discover consistencies within the structure of so much microcontrollers. Microcontrollers: basics and functions with PIC specializes in those universal parts to explain the basics of microcontroller layout and programming. utilizing transparent, concise language and a top-bottom strategy, the booklet describes the elements that make up a microcontroller, how they paintings, and the way they have interaction with one another. It additionally explains the best way to application medium-end graphics utilizing assembler language.

Examines analog in addition to electronic indications


This quantity describes the constitution and assets of normal microcontrollers in addition to PIC microcontrollers, with a unique specialise in medium-end units. The authors speak about reminiscence association and constitution, and the assembler language used for programming medium-end PIC microcontrollers. additionally they discover how microcontrollers can gather, approach, and generate electronic signs, explaining to be had suggestions to accommodate parallel enter or output, peripherals, assets for real-time use, interrupts, and the categorical features of serial facts interfaces in PIC microcontrollers. eventually, the ebook describes the purchase and new release of analog signs both utilizing assets contained in the chip or by way of connecting peripheral circuits.

Provides hands-on rationalization

Using functional examples and functions to complement every one subject, this quantity offers the instruments to entirely clutch the structure and programming of microcontrollers. It avoids overly particular information so readers are speedy led towards layout implementation. After studying the fabric during this textual content, they are going to know how to successfully use PIC microcontrollers in a layout process.

High Performance Parallelism Pearls: Multicore and Many-core Programming Approaches, Volume 2

Excessive functionality Parallelism Pearls quantity 2 deals one other set of examples that show the best way to leverage parallelism. just like quantity 1, the innovations incorporated right here clarify how one can use processors and coprocessors with an identical programming – illustrating the simplest how one can mix Xeon Phi coprocessors with Xeon and different multicore processors.

Example text

Tests can also be considered to be another form of documentation, since they document the expected functionality of your code by testing that it performs the way it should. The Simpletest testing framework allows you to create both unit tests (low-level tests of specific functions or classes) and functional tests (higher-level tests that can involve simulating a browser and checking that pages and forms behave as they should); both can be appropriate for code that you write. org/ project/examples) have tests, and there are also many tests in Drupal core.

While that is sometimes necessary, many use cases are covered by the contributed Custom Breadcrumbs module, which is quite easy to set up. Mistake: Programming Too Much | 37 Site configuration export The contributed Features module lets you export much of the configuration of a Drupal site to PHP code. For instance, you can export your custom content types and fields, your Views, and many other settings; the result is a module, which you can then put into revision control or share with another site.

However, note that some Drupal API functions, such as l() (for making links), cleanse input themselves, so read the function documentation and don’t doublecleanse. Examples: // Bad: print '

' . $text . '

'; print '' . $text . ''; print l(check_plain($text), check_url($url)); // Good: print '

' . check_plain($text) . org under the “Sanitization” topic. org/writing-secure-code 28 | Chapter 2: Drupal Programming Principles • “Mistake: Saving PHP Code in the Database” (page 43) Checking Drupal Permissions Drupal has a rich permission system, which your modules need to interact with properly to ensure that users, including anonymous site visitors, are only allowed to see infor‐ mation and perform actions that they have permission for.
