Compiler/CC2540: IAR Workbench compiler int64

Part Number: CC2540

Tool/software: TI C/C++ Compiler

Hi,

I recently started to work with IAR and CC2540. I'm currently building some code to communicate with the BME280 sensor. There are some operations that require 64bit integers. I searched in multiple places and haven't found support for 64bit integers in the IAR Workbench compiler.

Is this type not supported?

Thank you!

    Hi,

    Have you tried using an integer with the type uint64_t or int64_t?
    I've tested it in IAR and it shouldn't cause any compilation errors.

    Is there a special header that needs to be included?
    I've tried with int64_t and int64 and it didn't compiled. I've searched through all the ble stack and there is no mention of int64 (apart from some commented code in CC2541ST).

    I displayed sizeof(long) and sizeof(long long) and both have 4 bytes. It seems to me that the compiler doesn't support 64 bit integers.

    I'm developing on SimpleBLEPeripheral project.

    Try including stdint.h

    I did misread what device you were using however it should still work.

    For IAR, the header should be included in a similar file path as this: C:\Program Files (x86)\IAR Systems\Embedded Workbench 7.0\8051\inc\dlib\c\stdint.h

    If you open the header file, you can see that int64_t and uint64_t are supported.

    It's not working. Maybe because that header is for Dlib. I use Clib (it cannot be changed to Dlib because the ble libraries are compiled for Clib).
