Hi Jan-Erik, Jan-Erik Soderholm wrote > Anyone having anything good/bad to say about MPLAB 6.50 ? Some 'experience': Somewhat positive: I found some errors in datasheets (an interchange of the deviceIDs of the 16F767 and 16F777, even in the errata DS80177a-1). But in the device info (PICxxxxxx.DEV) files in MPLAB 6.50 the device IDs are correct for these PICS! Negative: I found also errors in the device info files. Most PICs have a revision code of 5 bits, some use 4 bits. But in the device info files of the appropriate PICs still a mask of 5 bits is defined. For my XWisp2 program I'm extracting the info I need from these files systematically, and I see lots of omissions! BTW. I don't report errors to MicroChip anymore. I have twice reported the doc error I mentioned above, per E-mail to the address that MicroChip specifies in its site for this purpose and in the Mocrocontroller Errata forum. But I got no response, nor did I see a correction. It gives me the feeling talking to a wall, and although they say walls have ears, this one apparently hasn't!
