MPLAB XC-DSC C Compiler
Support – The new compiler is mentioned where applicable through the
document, notably in 10.1 Compiler Advisor, 10.3.1 Code Coverage
(in the MPLAB Analysis Tool Suite), 11.2 CI/CD Wizard and 14.6 Memory
Windows - DSC Devices (a new section).
Content
Manager renamed to Documentation Manager
where applicable through the document.
5.1 Create New Project - Update to New Project wizard. Create and group
multiple projects with a single run through. For Dual Core device or Trust Zone
projects on 32-bit devices, development flow is more efficient.
6.3.9 Group of Projects – New section on a simpler method of grouping
projects for development.
6.5.2 Checksum/CRC32 - “CK Hexmate Checksum” subsection added to
describe, for MPLAB XC8, the Project Properties > XC Linker > Additional options > Checksum option for PIC and AVR devices.
9. Arm® Cortex®-M Features Support – New section for support of several
additional features.
9.1 Smart programming – Program only areas of memory that differ between
the IDE and target device (except for SAM L10/11, SAM RH7x and PIC32CZ/CK
devices.) To enable, select in Project Properties > ToolName > Program
Options.
9.2 Diagnostics – Logging for Arm Cortex devices.
9.3 Event Recoder - Moved from 8.7 into this section.
9.4 printf – Stream printf data to the MPLAB X Output window through a
connected debug tool. The semihosting mechanism is used.
9.5 Runtime Watch – Watch variable values change and read/write data to a
Live View window. Uses Window > Debugging > Live Viewers > Runtime Watch
window.
9.6 MTB trace – Support for trace using Micro Trace Buffer (depending on
the device) with output to a Live View window. Uses Window > Debugging > Live
Viewers > MTB window.
9.7 Monitor Mode Debug (MMD) – While debugging, halt a very low-level
interrupt (the monitor) while higher priority interrupts continue running.
Useful for motor control or communication stacks. To enable, add a specific
symbol in the firmware. Note: At this time, customers will have to write their
own monitor.
