merging ble_app_uart with spi

[Den]

Hi,

I am working on "nRf52832 - PC10040" based ISP1507/. I have already adapted the peripheral/spi example of SDK 15.0.0 to my needs. Now, I want to merge this spi example to SDK15.2.0 ble_app_uart so that I can send the data I receive from spi via ble. SPI will be master by the way. 

I believe I have added the necessary files and paths and make the necessary changes in the sdk_config.h. I have copied settings from the spi example. The exactly the same driver modules that are enabled in the spi example are enabled in the ble_app_uart now. The only difference is instead of SPI instance 0 I have enabled instance 1 since instance 1 is use by uart. I used to have some errors but they are solved. 

However I have not been able to overcome the following error. SPIS is not used and the function nrfx_spis_init is not called anywhere in the program. What I am missing?

.\_build\nrf52832_xxaa.axf: Error: L6218E: Undefined symbol nrfx_spis_init (referred from nrf_drv_spis.o).
Not enough information to list image symbols.
Finished: 1 information, 0 warning and 1 error messages.
".\_build\nrf52832_xxaa.axf" - 1 Error(s), 16 Warning(s).

Thanks,

Hello,

It doesn't seem as UART and SPIM overlap if you look at the instantiation table, so no need to change from 0 to 1:

Make sure that you set include path to where the spim driver and src files are located in your project, and include the spim source files to the project, similar to the spi project. You also need to include the spim defines in sdk_config.h I don't see any reason why you should need to include or add spis to your project, I must assume you have miss-clicked or miss-copied spis instead of spim somewhere in the process, which is why you are getting a nrfx_spis_init build error.

Best regards,
