Drivers from nRF5_SDK to Mesh SDK

[cdugue]

Hello,

I would like to add the ST7735 driver from the nRF5_SDK to the Mesh SDK along with the necessary components (SPI,..). I copied the entire components directory to my Mesh SDK. But I have an issue with the cmake operation when trying to build the example as it cannot find the include files.

What is the best way to solve this issue? Should I modify some CMake files?

Thanks.

Hi cdugue,

Yes, you need to include the path to the header file (target_include_directories), also include the .c file into the source list (add_executable) into the cmake file.

Hi Hung, I tried to do that but I don't know if I am doing it the right way as there are a lot of dependencies so a lot of files to link. For example, I am adding the st7735 driver to the ligher_server example in Mesh SDK. I am modifying the CMakeLists.txt file in examples/light_switch/server. I added the following:

`add_executable(${target}
    "${CMAKE_SOURCE_DIR}/components/drivers_ext/st7735/st7735.c"
    "${CMAKE_SOURCE_DIR}/components/drivers_nrf/spi_master/nrf_drv_spi.c" )`

`target_include_directories(${target} PUBLIC
    "${CMAKE_SOURCE_DIR}/components/drivers_ext/st7735"
    "${CMAKE_SOURCE_DIR}/components/libraries/util"
    "${CMAKE_SOURCE_DIR}/external/thedotfactory_fonts"
)`

Note: I didn't copy all the lines I added but basically I tried to link the c and h files for each function that was undefined during the make command. But I still get a lot of errors when compiling.

Hi cdugue,

There could be more complex than that because of many dependencies. I would suggest to have a look at our gfx example (which uses st7735) in the SDK and check the dependencies needed. We will try to come up with an example of using SDK driver inside Mesh SDK in the next few days.

Hi Hung, Thank you, I will look for this example then.

Hi cdugue,

I attached here an example using PWM library from nRF5 SDK. The SPI library should be very similar. You would need to copy the nRF5 SDK v14.1 "components" folder into mesh SDK at \external\nRF5_SDK_14.1

Base on the example, you should be able to add SPI the same way as PWM.
