ad_spi_open( NAME ) in SmartSnippets Studio gives undefined reference

Hello,

Trying to get a project compiled in the SmartSnippets Studio (v2.0.7.1335), cloned project is dk_apps/features/ble_peripheral.

All works great but in one of my files I have a statement [ dev = ad_spi_open( MYNAME ) ]

The compiler complains with an error undefined reference to 'MYNAME'

The project includes an include file my_platform_devices.h which has the statement:

SPI_BUS(SPI1)
SPI_SLAVE_DEVICE(SPI1, MYNAME, HW_GPIO_PORT_3, HW_GPIO_PIN_2, HW_SPI_WORD_8BIT,
HW_SPI_POL_LOW, HW_SPI_PHA_MODE_0, HW_SPI_FREQ_DIV_8, 0);
SPI_BUS_END

If I hover over the statement in the c file I even see the define in the include file.

Any suggestions on where to look/how to resolve this?

SDK=DA1468x_DA15xxx_SDK_1.0.14.1081

Thanks.

Hi Myken,

Did you create a spi_device object like follow?

spi_device dev = ad_spi_open(MYNAME);

请试试这个,让我知道。

Also, I would strongly recommend you to have a look atSPI Adapter Concepttutorial from our support portal.

Thanks, PM_Dialog

Yes, I did:

spi_device dev; dev = ad_spi_open( MYNAME );

Forgot to copy first part.

Basically the software as is works and runs, that is I compiled and linked it using plain makefiles and tested it (works okay).
Now I try to get the same project working in SmartSnippets Studio. All is good except this part.
So probably there is something wrong in the project setup in SmartSnippets Studio.

If I do (in my_platform_devices.h):

SPI_BUS(SPI1) SPI_SLAVE_DEVICE(SPI1, MYOTHERNAME, HW_GPIO_PORT_3, ......

I get an error during compiling the file (my_spi_file.c) with the spi_device dev = ad_spi_open( MYNAME );
error: 'MYNAME' undeclared (first use in this function)

If I change it back to:

SPI_BUS(SPI1) SPI_SLAVE_DEVICE(SPI1, MYNAME, HW_GPIO_PORT_3, ......

I don't get a compiler error but a linking error
我的_spi_file.o: In function 'my_function':
我的_spi_file.c:xxx: undefined reference to 'MYNAME'

I can see that the file sdk/adapters/scr/ad_spi.c is compiled (have .o and .d files)
I included the ad_spi.h file.

If I open the my_platform_devices.h file I see in the "outline" tab MYNAME: const void* const, don't know if that mean anything.

My code looks identical to the code in "5. Code Overview" from the tutorial you reference to (MYNAME iso ECHO_LOOP).

Something wrong with compile/linking order??? Forgot to tick a box?

Thanks.

Never mind, just (3 minutes

Never mind, just (3 minutes ago) found the solution.
Turns out, my platform_devices.h file was not in the config subdirectory of my (cloned) project. With makefiles that is not important, apparently in SmartSnippets it is.
