MPLAB v3.20 beta release is available on the WWW (should be posted by the end of the day) and Microchip BBS site (now, in the INT-REL directory). This version is numbered v3.12.14 until official release. MPLAB has these new features: £ PRO MATE device programmer support £ New parts support: £ PIC12C671/672 - MPASM £ PIC16C642/662 - MPASM, MPLAB-SIM, PICMASTER, PICSTART Plus, PRO MATE £ PIC16C66/67/76/77 - MPASM, MPLAB-SIM, PICMASTER, PICSTART Plus, PRO MATE £ PIC17C752/756 - MPASM, MPLAB-SIM, PICSTART Plus, PRO MATE £ PIC16C715 - PICMASTER (PIC16C715 support already exists in other tools) £ Improvements to PICSTART Plus user interface £ Retention of previous tool bar customizations £ 16-bit and 1-bit watch windows £ Stimulus file disable £ Improved Help files £ Many fixes for reported problems MPLAB v3.12.14 fixes the following reported problems with previous versions: - Various data problems using the PICSTART Plus with MPLAB-SIM and PICMASTER emulator. Data was not always updated or presented correctly. - All memory is cleared when changing processors or before importing the object code from a new project. MPLAB v3.12.14 still has the following known problems: - Processor configuration bits set in source code do not change the corresponding emulator/simulator processor mode. - No warnings are issued when loading hex files that are out of range or contain data with more bits than supported by current processor. We would request constructive feedback about this latest version. We rate problems according to these categories: £ 1. System crash £ 2. Serious problem, --no easy work around £ 3. Problem, --work-around available £ 4. Design request --"it would be nice" £ 5. Can't duplicate --document, so we don't forget about it FYI, we have no known level 1's or 2's, a few 3's (those listed above), and we've got a lot of #4's. If we had all the time in the world, we would like to address them (or even debate the ones that are contradictory with other requests). We're more interested in what you need to get your jobs done. If you can't use MPLAB to easily and quickly simulate, emulate, or program your Microchip PIC devices, please let us know immediately. Private post directly (but depending upon the number of messages, don't expect an immediate response). Faster responses are possible on the Microchip BBS.
