PORT_3 and PORT_4 interrupts

Other Parts Discussed in Thread: MSP430F6638, MSP430WARE

Hello,

The driverlib included in the release MSP430ware_1_40_01_19 does not support the interrupt capabilities of the port 3 and 4 of the MSP430f6638 MCUs. Will these capabilities be included in futures versions?

Regards,

Raul.

    Hi Raul,

    Only P1 and P2 of the MSP430F6638 are interrupt capable.  Not all MSP430s have interrupt capabilities on P3 and P4.

    Thanks,

    Ryan M. Brown

    Both the datasheet and headers for the F6638 indicate it supports interrupts on PORT3 and PORT4.

    After further research, you are correct.  The F6638 is interrupt capable on P3 and P4.  I apologize for the confusion.  It is possible that MSP430Ware only includes libraries of features that are incorporated in every MSP430 of the family.  I do not know if or when libraries for P3 and P4 interrupts will be included.

    Thanks,

    Ryan M. Brown

    I am very sure that MSP430Ware only does what it does, nothing more nothing less.

    It shouldn't be all that hard to extend the library yourself. After all, it is delivered in source code format. If you are already using DriverLib, then this is easier than starting from scratch.

    Thsi MSP is rather new. Until recently, no MSP ever had interrupt capabilities except for P1 and P2. Then i learned about the Wolverines with interrupts on all (?) ports and now the 663x.
    Apparently the DriverLib hasn't inplemented this new feature yet.

    But as already suggested, it should be easy to extend the library by yourself. Interrupts for port 3 do not differ from port 1 more than port 2 does.
