CCS/MSP430FR2355: Does MSP430® IQmathLib version 01.10.00.05 support MSP430FR2355?

Part Number: MSP430FR2355
Other Parts Discussed in Thread: MSP430FR2633

Tool/software: Code Composer Studio

Hi team,

    Does MSP430® IQmathLib version 01.10.00.05 support MSP430FR2355?

    If MSP430FR2355 is supported, which library under "\msp430\IQMATHLIB_01_10_00_05\libraries\CCS" should be linked to the project?

    Can you provide the example code about how to use MPY32 to achieve multiply operation in C language?

    Hello,

    the IQMath library is supporting all MSP430 devices. Please find here a screen shot of the resources within CCS. There you can find the User's Guide, which explains in more detail, how to apply the library to the MSP430 device of your selection.

    Best regards

    Hi Peter,

         Thanks for your reply.

         1.Actually I have already read this user guide. However, I don't know which library I should add to the project according to 2.3.1(4xx, or 5xx and 6xx?). There are many folders under "\msp430\IQMATHLIB_01_10_00_05\libraries\CCS" and I don't know which .lib is applicable to MSP430FR2355.

         2.Besides, I can't find MSP430FR2355 in the support list of IQMATHLIB_01_10_00_05 according to the following screen shot, which can be found under IQmath Library/Release Notes in your  screen shot. Can you help to confirm about it?

         3.Will the code use MPY32 if _IQNMPY() is used in code? And how to confirm this?

    Hi Charles,

    although not listed, the libraries should support also the FR2355. The FR2xxx have the MSP430X CPUX

    Our colleagues are using the MPY32_5xx_6xx_CPUX.... libraries for the MSP430FR2633 successfully, and that's a device with the same architecture and features of the MPY32. So this should also work for the MSP430FR2355.

    Please see here what our CapTIvate Design Center is including for MSP430FR2633.

    3. To verify the implementation, you could take a look at the disassembly at the respective function. There you can see whether the compiler has used a SW based calculation, or if it is accessing the MPY32 registers.

    Best regards

    Peter
