I downloaded the EAGLE library from one of the MSP430 product pages (thank you, TI, for creating these for us!) and found a bug. (I have library v16.)
It seems that all of the symbols for the G* devices have pins that are not on the grid. It therefore becomes impossible to connect a net to these pins. (Yes, it can be done if I change the grid in my schematic, but really, a cardinal rule of EAGLE is that all pins should be on the default grid.)
Can this be addressed in the next rev of the library, please? I spot checked some of the other symbols and it appears that only the G* symbols suffer from this problem.
