MPLAB X IDE Changelog

What's new in MPLAB X IDE 2.35

Feb 27, 2015
  • Reading of PIC32MZ serial number to the Output window – The serial number on PIC32MZ devices will now be read on connection and displayed in the Output window.
  • Programming available for last Boot memory area on PIC32MZ devices – The last area of PIC32MZ boot memory is now programmable.
  • MPLAB PM3 Firmware Split – Due to increasing device support, the programmer firmware must be split between PIC32 devices and non-PIC32 devices. If you do production programming, ensure that you select your device before heading out to the production floor or you will not be able to change the firmware. A fix is being worked on.
  • Add libs and loadables to package – Include libraries and loadables when zipping a project package. If the loadable is a project, is will be zipped as well.
  • Memory usage based on compiler input – Compiler-reported usage of device memory, displayed in the Dashboard window.

New in MPLAB X IDE 2.30 (Jan 9, 2015)

  • Generic Compiler Plugin – This provides the ability to add a generic or custom compiler to the IDE through the Tools>Options dialog. From here the compiler will be visible to be selectable within the Project Properties window for the devices it is declared capable of supporting.
  • Files Committed to Repository – Currently when adding a project to a version control repository, all directories and files will be shown to be added. Some directories and files should not be added and are documented in the MPLABX help file. Now only the necessarily directories/files in the add window are shown.
  • MPLAB Provide Break Reason – When possible, the debugger tab in the MPLAB X IDE Output window will display the reason a device has halted. This feature is limited to the information that the silicon provides so not every device will have this capability and not all break reasons can be determined.
  • Serial Communication for MPLAB PM3 (and MPLAB IPE) – Allow serial communication between the MPLAB PM3 and PC via a COM port. This will be similar to MPLAB ICE v8 operation.
  • Preserve UserID in MPLAB PM3 Standalone Mode – Implementation of preserve UserID memory for MPLAB PM3 standalone mode.
  • Repairs and Enhancements:
  • When the tool is powering the target board, MPLAB X IDE hangs when "maintain active connection to hardware tool" is checked and "apply" is clicked in the project properties window.
  • On building in MPLABX IDE and REAL ICE as debugging tool for 32MX1xx/2xx devices the
  • -mreserve=boot option with same value is being passed twice by the MPLABX IDE
  • Programming issues when switching between projects while maintaining an active connection
  • Simulation of stalls during the RAW data dependencies are not supported.
  • PIC24HJXXXGPX06A/X08A/X10A family of devices is missing the DMA5 interrupt information.
  • Bit implementation of LATF register is incorrect in dsPIC30F6012. When PORTF is set as all output by clearing TRISF, on writing 0xFFFF to LATF, the SFR must have value 0x007F. But, in dsPIC30F6012, in the Watch window, it can be observed that LATF is getting updated with the value 0x01FF.
  • PxOVDCON registers have incorrect reset values. The reset values for PxOVDCON.POVDxH and .POVDxL fields are 0, and should be 1. This error causes the simulator PWM to force outputs to low at all times.
  • Bit implementation of AD2CHS0 register is incorrect for certain dsPIC33F devices.
  • There are some missing definitions in the .include files for PIC18F25K50.inc and PIC18F45K50.inc files. Missing registers. POSTINC0 POSTDEC0 PREINC0 PLUSW0 INDF1 POSTINC1 POSTDEC1 PREINC1 PLUSW1 INDF2 POSTINC2 POSTDEC2 PREINC2 PLUSW2
  • PIC18F85K90 has T7CKI pin described in the include file, but should be removed.
  • As per device datasheet of PIC24FV32KA302, bit 14 of I2C1CON is unimplemented but in MPLAB X, bit 14 of I2C1CON shown as "I2CFRZ"
  • There are bit name differences in the STATUS and OPTION registers between the datasheet and the support tools, such as header files or SFRs in the tools.
  • The WPUB Register is missing from the pic18f45k50.h header file
  • Device ID mismatch error seen with PIC32MX440F128H in MPLAB X IDE.
  • The Internal RC Frequency select (IRCF) bits are improperly labeled as IRFC in 16F88X MPLAB XC8 header files.
