Hi guys,
An update about MPLAB 860
About 2 weeks ago I wrote:

I've spent many hours to adapt the dev2jal script and related helper
files to the changes in MPLAB 8.60. In general I succeeded, but I'm
afraid I cannot get all device files 100% compatible with the previous.
Some fuse_def names have changed: for example for several PICs PLLEN is
now PLLDIV. For a few PICs I've checked with the datasheet and PLLDIV
seems to be in accordance with the datasheet. This means we should
accept this change (and other similar changes). But it means the many
Jallib samples (and probably user programs) don't compile anymore
without errors. The samples can be changed by us, but not the user
programs...
Any suggestions how to proceed (/ consolidate?)?
There are some issues which make it almost impossible (or only with much
work) to find a solution. Microchip is at some places extremely and
stupidly inconsistent. For example in one .dev file (e.g. 16f876) 'WRT
enabled' means that writing of flash memory is allowed, while in another
.dev file (e.g. 16f876a) the same 'WRT enabled' means writing of flash
is NOT allowed! How am I supposed to know what is meant in a specific
case without reading the datasheet (which may be wrong as well)? VERY
ANNOYING!
After this experience, the announcement of MPLAB X and after working
almost 3 years on device file generation) I'm beginning to think of
quitting. It's time for another challenge for me.
Sorry for the negative news, nevertheless: have a nice weekend!
Regards, Rob.
