This book is for developers who design and program devices that use the
Universal Serial Bus (USB) interface. The goal is to introduce you to USB
and to help you get your devices up and communicating as quickly and easily
as possible.
The purpose of this example is to demonstrate that the
functioning of External interrupts (INT0, INT1, INT4, INT5 and INT6) and
how toset them up.
This directory contains the frameworks fw.c, the test program extr_intr.c
and the external interrupt service routines isr.c. This was compiled
using micro vision2.
Software developers need to have a number of traits in order to practice their
craft well. First, they must be good analytical thinkers and problem solvers. A
developer’s primary role is to create software that solves business problems.
This requires analyzing customer needs and coming up with successful, creative
solutions.

This the second tutorial of the Writing Device Drivers series. There seems to be a lot of interest in the topic, so this article will pick up where the first left off. The main focus of these articles will be to build up little by little the knowledge needed to write device drivers. In this article, we will be building on the same example source code used in part one. In this article, we will expand on that code to include Read functionality, Handle Input/Ouput Controls also known as IOCTLs, and learn a bit more about IRPs.
Ink Blotting
One method for escaping from a maze is via ‘ink-blotting’. In this method your starting square
is marked with the number ‘1’. All free, valid squares north, south, east and west around the
number ‘1‘ are marked with a number ‘2’. In the next step, all free, valid squares around the two
are marked with a ‘3’ and the process is repeated iteratively until :
The exit is found (a free square other than the starting position is reached on the very edge
of the maze), or,
No more free squares are available, and hence no exit is possible.
Ideal for large low power (nanoWatt) and connectivity applications that benefit from the availability of four serial ports: double synchronous serial ports (I² C™ and SPI™ ) and double asynchronous (LIN capable) serial ports. Large amounts of RAM memory for buffering and FLASH program memory make it ideal for instrumentation panels, TCP/IP enabled embedded applications as well as metering and industrial control and monitoring applications. While operating up to 40 MHz, it is also backward software and hardware compatible with the PIC18F8720.
