Started using MPLAB340 yesterday Most seem to work OK, except some annoyances. But when it hit some breakpoint MPLAB hangs completely! (OK. maybe it simulates the hang of the PIC chip...?? ;-) ) But other breakpoints are OK, just some not?? I changed the code and then it did not hang. (the code worked OK both times if i did not set that breakpoint) Feels weird! Anybody else having this problem? Windows pops up a message saying, translated to english "Common protection error" as follow below: ------------------------------------------------ MPLAB orsakade ett allmŠnt skyddsfel i modul MPLAB.EXE pŒ adress 001b:00000550.

I of course still have MPLAB 3.31 in a separate directory, so I just copy files between (except the .pjt file) so there is no fire on the roof, just a pity 3.40 seem not have grown up yet. /Morgan / Morgan Olsson, MORGANS REGLERTEKNIK, SE-277 35 KIVIK, Sweden \ \ mrt@iname.com, ph: +46 (0)414 70741; fax +46 (0)414 70331 /
