MSP430FG6426: MSP430FG6426

Part Number: MSP430FG6426
Other Parts Discussed in Thread: MSP430G2553, , MSP430WARE

Hello,
I would like to implement "SMBUS" on our desired MSP430FG6426 micrcontroller. But so far, I get a sample code of SMBUS for MSP430G2553. I try to do the porting of code from MSP430G2553 to MSP430FG6426 controller ( http://www.ti.com/tool/MSP430-SMBUS . But due to complexity and register mismatching, its really hard to porting.

I would like to get an example code of "SMBUS" for MSP430FG6426 controller. Code could be just like blinking an led according to Master Command to Slave.

I am using CCS as IDE and 4MHz crystal of the prototype board.

Looking for the kind help.

    Hello,

    We currently only have examples for our SMBUSLib for the MSP430G2553 and one of our MSP430FR5xx/6xx devices. The main difference between these devices is one example takes advantage of the eUSCI (MSP430FR5xx/6xx) to do some additional SMBUS handling in HW, versus doing this in SW for our typical USCI (MSP430G2553 example). The example you found for the MSP430G2553 is going to be the closest example for you to port from. The biggest difference between the USCI implementation within the MSP430G2553 verses the MSP430FG6426, is the ISR structure. The MSP430FG6426 has its own ISRs for USCI, while the G2553 shares an ISR with other functions as well.

    As a side note, SMBUSLib can also be found within TI Resource Explorer both in CCS and at http://dev.ti.com . It is found within the Libraries menu inside MSP430Ware.
