great thanks it works

RE: "twi + softdevice" not working !!! makefile build fails

Ladasky — Wed, 04 May 2016 18:37:58 GMT

One of my habits is to search the Nordic SDK for certain file names when they appear in my compiler error messages. This has taught me things that I have trouble finding in the SDK documentation or tutorials.

I'm using the PCA 10036 board and SDK 0.9.2. There are THREE versions of the file nrf_error.h in SDK 0.9.2. They are located in the following directories:

components/softdevice/s132/headers
components/softdevice/s212/headers
components/drivers_nrf/nrf_soc_nosd

Eventually I figured out that "nosd" stands for "NO SoftDevice." Hope that helps someone else.

The project needs to have the file nrf_drv_config.h added, and then edited to enable the TWI interface. Either set TWI0_ENABLED to 1 or TWI1_ENABLED to 1, depending on which of the two TWI peripherals you want to use. And set TWI0_USE_EASY_DMA or TWI1_USE_EASY_DMA to 0, since Easy DMA is only supported for nRF52.

what could be the problem now

RE: "twi + softdevice" not working !!! makefile build fails

Paolo D — Wed, 04 May 2016 16:53:30 GMT

Do not add the directory ../../../../../../components/drivers_nrf/nrf_soc_nosd to your include path if you are using the SoftDevice. That directory is only for projects that don't use the SoftDevice.

Instead, add the directory ../../../../../../components/softdevice/s130/headers to your include path.
