Microcontrollers: From Assembly Language to C Using the PIC24 Family

This site introduces students, educators, and hobbyists to the capabilities of a powerful modern microcontroller, the Microchip PIC24.

Microcontrollers: From Assembly Language to C Using the PIC24 Family covers a wide range of topics in a straightforward, conversational fashion attainable to students and hobbyists alike. Topics include PIC24 associates language programming and hardware interfacing using the C language. The text introduces the PIC24 library collection and contains an extensive set of examples carefully explained in the text. The text then presents ESOS, a low-overhead operating system for the PIC24 and provides a capstone design chapter in which the designs of an audio tape/playback system, reflow oven and a remote-controlled robot are presented. The book is available from Delmar Learning. A video tutorials page is also available that contains selected topics from the book.

The PIC24 library collection accompanying the text provides a tested, well-documented set of libraries illustrated by numerous examples which simplify many common programming tasks for the PIC24. The getting started guide provides all information necessary to get your PIC24 organisation upward and running. With an operational system, the PIC24 support library provides back up for all major subsystems of the PIC24. The ESOS library contains a low-overhead, cooperative Os.

The ECE3724 course on microprocessors features on-line lecture notes and lab experiments which cover major portions of the text, including iv associates labs and half-dozen hardware labs, including experiments with a digital thermometer and fan speed command.

    • 3-Mar-2014: The code archive is updated, providing some bug fixes and cleanup. See the release notes for more details.

    • 9-Jul-2013: A new, beta release containing major updates to the code archive in the PIC24 library collection is available, featuring preliminary MPLAB X back up, redesigned GPIO macros, and much more. See the release notes for more than details.

    • i-29-2013: Here are some notes on the flipped classroom approach that we utilize in our ECE3724 course.

    • xv-Aug-2012: There are more video lectures bachelor for our ECE3724 course and more will be added every bit the Fall 2012 semester progresses.

    • 22-Mar-2012: The code annal has been updated to provide initial support for the PIC24E/dsPIC33E families, every bit well equally some some bug fixes and cleanup. See the release notes for more details. This page discusses some of the differences between the PIC24H and PIC24E families.

    • 1-Mar-2012: The lawmaking archive is updated, providing some bug fixes and cleanup. Encounter the release notes for more than details.

    • 25-Aug-2011: The code annal is updated, providing some bug fixes and cleanup. See the release notes for more details.

    • 12-Apr-2011: The code annal is updated, adding back up for two additional hardware platforms. See the getting started page for currently supported platforms and the release notes for more details.

    • 8-Apr-2011: The code archive is updated with a number of improvements and some significant changes. The common/, include/, and lkr/ directories have been moved to lib/common/, lib/include/, and lib/lkr/. All projection files in the library have been updated with these new paths; utilize these as a template to upgrade your current projects.

    • January. 2011: The examples in the code archive have been updated so that all examples link with V3.25 of the MPLAB C Compiler for PIC24 and dsPIC in Lite fashion. A few examples used printf statements with floating point formats, and these no longer link on devices with only 2K RAM (printf format strings are built in data memory) equally the printf data buffer reserved past the compiler has greatly increased in this compiler version. On CPUs with greater than 2K RAM the lawmaking examples work the same as before; on CPUs with 2K RAM (such as the PIC24HJ32GP202) conditional compilation is used to select lawmaking that only uses printf statements with integer formats for output strings. Most of the affected code is in Chapter eleven, such as chap11/adc2pots1.c or chap11/adc_test.c. The code update too includes a user-submitted fix for the Bully Bootloader when loading software greater than 64K (thanks John North. and Vaifro D.!). Microchip has promised a set for the printf information RAM buffer usage, and the printf lawmaking changes in the examples volition exist backed out once that fix is released.
