32-bit PIC® MCUs

The ARM® Toolchain is a collection of tools/libraries used to create applications for ARM microcontrollers. This collection includes compiler, assembler, linker and Standard C and math libraries.

Most of these tools are based on efforts from GNU (www.gnu.org), and some are developed by Microchip. For more information please refer to the release notes.

The Atmel AVR GNU Toolchain is also available as part of Atmel Studio. Only those users who wish to run the Atmel AVR GNU Toolchain as standalone tools from the command line need to download and install this package. There are two sets of downloads, one for Windows® and one for Linux® operating systems.

Measure how well your code is tested using MPLAB Code Coverage. This licensed feature is available in all MPLAB XC Compilers and is fully integrated into MPLAB X IDE to provide analytical and navigational tools, dashboards, summaries and reports. The MPLAB Code Coverage tool quickly displays which lines of code have executed and which ones have not. Unlike other solutions, it runs untethered and self-contained so no need to add clumsy cabling or fragile wires. With minimal impact to code size (<1%) and execution speed, testing can be completed in a single execution pass, avoiding expensive test hardware with a larger MCU. Powerful, intuitive tools permit quick navigation of coverage results within MPLAB X IDE for smooth transitions between test suite development and analysis. Summary views offer configurable dashboards of critical results. Custom reports can be generated in HTML and CSV formats with selectable content to meet your specific quality certification needs. MPLAB Code Coverage builds confidence in your application testing process without the hassle.

Microchip’s line of award-winning MPLAB^® XC C Compilers provides a comprehensive solution for your project’s software development and is offered in free, unrestricted-use downloads. These compilers integrate into Microchip's MPLAB^® X IDE, are compatible with all Microchip debuggers and emulators, and run on Windows, Linux and Mac OS X.Finding the right compiler to support your device is simple:

• MPLAB XC8 supports all 8-bit PIC MCUs
• MPLAB XC16 supports all 16-bit PIC MCUs and dsPICs
• MPLAB XC32/32++ supports all 32-bit PIC MCUs

The MPLAB XC Network Server License is a shared license. It allows one person to compile at a time. Once used, the license remains captured by that person for 60 minutes, during which no one else can use it. If that person compiles again, the 60 minutes starts over.

The license is not compatible with virtual machines unless combined with an MPLAB Virtual Machine License for Network Licenses, SW006021-VM.

The MPLAB XC PRO Network Server Licenses also come with 12 months of High Priority Access (HPA) - a maintenance subscription providing web access to new compiler versions, priority technical support for the compiler and free shipping on all development tool orders on Microchip Direct.

Product numbers are:

• MPLAB XC8 PRO: SW006021-2N
• MPLAB XC16 PRO: SW006022-2N
• MPLAB XC32++ PRO: SW006023-3N

For more information and documentation, see the MPLAB XC C Compilers page.

To continue to provide the best compiler products possible, on September 1, 2020, this type of MPLAB XC C compiler license will change in how it functions. It will change in the following ways:

1. All MPLAB XC PRO licenses activated after this date will expire after one year unless the HPA is renewed
2. An existing MPLAB XC PRO license will change to this new model as the HPA is renewed and applied to it

Note that any existing licenses will continue to function as they always have, and there will be no extra fees for letting the HPA lapse. HPA itself will not change. It will still provide you with updates to new compiler versions, priority access to technical support and free shipping on your development tool orders.

We are committed to continuously improving our world-class line of MPLAB XC compilers to provide you with valuable and easy-to-use software development solutions. Please email us at SW.Licensing@microchip.com if you have any questions.

Site License
MPLAB® XC Compilers produce highly optimized code. Site licenses are available in the PRO edition, which has the most features and produces the best code optimization of any of Microchip's compilers. The site license is installed on a network and can be quoted for seats of five and greater, which can be mixed between any of the compilers: MPLAB XC8, MPLAB XC16 and MPLAB XC32. Site licenses can only be ordered for the PRO edition. Please contact a local sales office for more information and a quote: Global Sales

• Intended to have one user per seat and installed on a network
• Restricted to the number of seats purchased
• Allows the administrator to add and remove users as needed by tying the licensed users by their host IDs.
• Allows for volume pricing
• Has a loan-out feature, so the license can be used like a node locked license for a specific amount of time (one month maximum on loan out)

Product numbers are:
MPLAB XC8 PRO: SW006021-SITE
MPLAB XC16 PRO: SW006022-SITE
MPLAB XC32/XC32++ PRO: SW006023-SITE

High Priority Access (HPA) for site licenses can also be ordered via quote through the local sales offices. The product number  for HPA for all license types is: SW006021-SITEH

Special Notice: MPLAB® XC Subscription License Price Adjustment

To continue to provide the best compiler products possible for all of Microchip’s devices, we will be making a price adjustment of $10 per month to all subscription licenses starting on September 1, 2020. During the month of September, the monthly subscription price will change from $29.95 to $39.95. Our subscription licenses will continue to be a flexible and convenient option that you can cancel or renew at will in one-month increments to meet your budget and design requirements.

MPLAB® XC Compilers produce highly optimized code. Subscription licenses unlock PRO-level optimizations, which produce the best execution speed and code size for all SAM® and PIC® microcontrollers (MCUs) and dsPIC® Digital Signal Controllers (DSCs) along with the best in compiler features.

The MPLAB XC32 PRO Subscription License is charged on a monthly basis, providing 8-bit designers the ability to make use of the most features and best code optimization only when needed in the design cycle. Subscribers will also have the ability to use any version MPLAB XC32/XC32++ Microchip compiler at any time, without the need for an active Microchip MPLAB XC High Priority Access (HPA) maintenance subscription. Unlike most software subscription solutions, the license is not cloud-based, providing designers the additional flexibility of using the license offline.

The subscription license is available as a download only, installed on a workstation and the license will be renewed every month by through internet connection.

This is a monthly subscription license and cannot be purchased in advance by buying multiples at one time (i.e. buying 12 licenses does not equal one year). Buying multiples at one time will result in multiple licenses being active every month.

This PRO Plugin for MPLAB® X IDE works with the MPLAB® REAL ICE™ In-Circuit Emulator to display the percentage of time spent in each application function, enhancing the software debugging capabilities of MPLAB® X IDE. It is used to measure the percentage of time spent in each function in order to determine where your application may be spending the greatest portion of time over an average collected set of data. It adds pre- and post-amble code to all functions in debug sessions. It aids in debugging and code optimization by tracking the number of function calls, parent functions, child functions and execution time. Each license is intended for one user. Available for device families with data capture, namely: PIC18F, PIC24F, PIC24EP, dsPIC33FJ, dsPIC33E, and those PIC32MX that support data capture. To find out if your device has data capture, please see the Dev Tool Selector.

The MPLAB X IDE Plugin - Halt Notifier provides an alert when a target is halted. These notifications can be customized with actions—such as issuing an audio alert, sending an email, or running a script.
This plugin is useful for debugging code in an efficient manner. Set the plugin, tend to other tasks and the plugin will send an alert when the debugging has halted (for example, a breakpoint).

From a script you can establish a text message to your cell phone, Yowsup, WhatsApp, tweet or run anything that collects data and archives it. Scripting gives you infinite possibilities.

This plug-in requires MPLAB X IDE version 3.30 or later.
