New Features in v1.05 Student Edition renamed Evaluation Version -- The student edition has been renamed the valuation version. This release also introduces a new academic version.
Improved 16- and 32-bit FFT functions in the DSP Library -- The FFT functions have been significantly improved and optimized for the PIC32 instruction set. See the 32-bit Language Tools Libraries document (DS51685) for more information. Please visit Microchip's website for the revision C of this document (DS51685C).
Binary Constants -- A sequence of binary digits preceded by 0b or 0B (the numeral '0' followed by the letter 'b' or 'B') is taken to be a binary integer. The binary digits consist of the numerals '0' and '1'. Note that this binary-constant syntax may not be accepted by other C compilers.
Linker Memory-Usage Report -- This optional, informational report allows you to easily determine the program- and data-memory usage of your application. It allows you to see how much space is used by the project being linked and how much space is available on the target device. The memory-usage report appears on stdout and in the optional map file.
- Using this feature with MPLAB IDE 8.20 and earlier -- On the linker's tab of the project build options, select to Use Alternate Settings. Add the --report-mem option to the Alternate Settings field. The memory-usage report will appear in the output window after a project build. (This option will appear as a checkbox in later MPLAB IDE releases.)
- Using this feature on the command prompt -- Add the --report-mem option to the linker's command line. If you are calling the linker via the compilation driver, use the driver's -Wl option to pass the --report-mem option to the linker. The memory-usage report will appear on stdout.
Improved malloc implementation -- This release contains a new malloc/free/realloc implementation based on the implementation written by Doug Lea and released to the public domain.
- This is not the fastest, most space-conserving, most portable, or most tunable malloc ever written. However it is among the fastest while also being among the most space-conserving, portable and tunable. Consistent balance across these factors results in a good general-purpose allocator.
- For a high-level description, see http://g.oswego.edu/dl/html/malloc.html
- This implementation is also provided with the Newlib C Library.
Instruction Macros -- The p32xxxx.h include file now contains a Nop() macro that issues a superscalar SSNOP instruction.
gettimeofday() weak stub -- The time.h clock() and time() functions require a user-provided gettimeofday() helper function. The compiler's library now provides a weak stub implementation that allows the project link to complete without error, but you should provide your own implementation appropriate for your application.
Microchip DSP Compatibility Wrapper functions -- This release provides new DSP wrapper functions intended to ease the migration from the Microchip DSP library for dsPIC DSCs to the general DSP library for PIC32 MCUs. See the 32-Bit Language Tools Libraries (DS51685C) document for more information on these new wrapper functions.
Updated peripheral-library documentation -- The 32-bit peripheral library document is now distributed as a compiled help file (*.chm) rather than a PDF file.
Support for PWP configuration bits -- The config pragma now supports enabling the Program Write Protect bits. See the PIC32MX Config Settings help file for information on the setting name and available values for each device.

Introducing a new tool for universities and educational institutions enabled with Microchip’s PIC32 32-bit microcontroller. The Eflightworks.net PIC32 on a DIP allows you to create and perform labs using a PIC32 in a form factor that fits on a typical breadboard. At the heart of the board is Microchip’s PIC32MX4 USB processor.
a new program for customers to trade in used video game titles in return for credit at Amazon.com. The program is launching with around 1,500 titles, all of which can be filtered and searched by platform. Once users have picked out the games they own and would like to exchange for credit, Amazon provides a pre-paid label that covers the cost of shipping. Amazon is offering those who trade in their games for credit a 10 percent markdown on games or video game accessories in the next two weeks.
. The book describes the PIC32 microcontroller and has many useful examples in C. Keep in mind that this is not an introductory C language book; It expects you to be familiar with C programming already.
