Microchip MPLAB releases

Microchip has recently released new versions of MPLAB C compilers.

You have version v3.21 of MPLAB C compiler MPLAB C Compiler for PIC18 MCUs

and version v3.10c of MPLAB C Compiler for PIC24 and dsPIC DSCs device (you'll need to go to any of the three16-bit compiler pages linked here for the update).

See the Release Notes for full details on new device support and changes made to these interim releases.

Also there is the MPLAB IDE v8.14 interim release .

This release has the following new features:
- 64-bit USB Drivers. USB drivers for Windows Vista 64-bit operating system allows MPLAB ICD 2, MPLAB REAL ICE and other tools using USB interfaces to operate in both Windows 32-bit and 64-bit platforms (XP-64 and Vista-64).
- Shadow SFRs. Some parts contain banked SFR sets, such as devices with CAN peripherals. MPLAB IDE now allows full monitoring and write access to those registers for debugging.
- Fast Stepping with 32 kHz Oscillators. Debugging targets at 32 kHz can be slow, since data speeds between MPLAB IDE and the device are rates limited by the clock speed. MPLAB IDE will switch to a faster internal oscillator when communicating to the device to speed up debugging.
- Peripheral Pin Select support in MPLAB SIM.
- Interface for Difference Tool. A generic facility is provided to launch a file difference checker.
- Persistent Bookmarks. Bookmarks will now be stored with the workspace, so that a re-launch of the workspace will also restore all bookmarks.

See the MPLAB v8.14 Release Notes for more information and a list of devices supported.
