If you know what you're doing, and if it is your code and properly maintained, this is fine. And as I already agreed, it is convenient to jsu tuse one header file. However, automatic selections can automatically fail and you don't know why. Sure, it is in the very most cases a user error, but the resulting error messages are then as useful in tracing it down as a generic 'there was an error' messge. > FWIW, the following text appears in the genericized headers (e.g., > msp430x54x.h) as they are provided by TI. /******************************************************************************/ /* Legacy Header File */ /* Not recommended for use in new projects. */ /* Please use the msp430.h file or the device specific header file */ /******************************************************************************/ Unfortunately. I see some TI engineers moving towards the convenient solution. However, they leave the people along with the problems that arise. Especially the demo projects, with their scarce or almost non-existent documentation cause problems for new users again and again. If the only remaining hint for which device this code was designed is removed in favor of a generic include, then they will be totally lost - and even support by experienced users becomes at least very difficult. The compiler could as well auto-include MSP430.h ;) Also, code using a generic include becomes less portable. Unless all compilers use the same or 100% compatible MSP430.h file. About the different supported devices, yes, I know this situation. You can as well include ifdefs for including the proper headers. It also makes clear which devices are supported by the code. Again, a generic include doesn't. (for UART functions, I even include different code depending on device, USCI/USART, available ram etc. So why not inlcuding the proper headers too?) IMHO, not everything TI does is 'right'. And if we come to a conclusion, we both together should have enough influence to make TI change their decisions. At least in details like this.
