SIMPLELINK-CC13XX-CC26XX-SDK: Using SDK 5.40 without GPIO++

Part Number: SIMPLELINK-CC13XX-CC26XX-SDK
Other Parts Discussed in Thread: SYSCONFIG

Hello! I have a makefile project that uses SDK 5.10 that I would like to upgrade to 5.40. When building with the new SDK, drivers_cc26x21.a throws errors that GPIO_config and GPIO_pinLower/UpperBound are undefined. The 5.10 based project doesn't use GPIO.h and instead uses PIN.h and a custom GPIO implementation. I've seen the GPIO++ porting guide that claims it is a drop in replacement, but it appears I need to define those symbols somewhere to get the library working. Even though I don't use GPIO.c/h, do I *have* to port to GPIO++ to use the 5.40 driver libs?

Thanks!

    Hi,

    Thank you for reaching out. I have notified the team of your message.

    The GPIO driver is used behind the scene by several other drivers (hence the behavior you are experiencing). When performing the GPIO++ migration, we usually recommend to run SysConfig once in order to generate the proper symbols.

    Best regards,

    Hi Connor

    It sounds like though there is upgrade for makefile from 5.10 to 5.40, but in the source code there are still old function. Please follow the guidance in GPIO++ Driver Porting Guide to do the porting from PIN to GPIO.

    Thanks.

    Best Regards,
