RE: How to use old TWI API on SDK15.0.0?

Hello,

In SDK15 the sdk_config.h files are often used to define these, although you could probably do it in the preprocessor defines as well.

I suggest that you look at the example found in:

SDK15\examples\peripheral\twi_scanner

in this project folder, you will find the file sdk_config.h under twi_scanner\pca10056\blank\config

Look at how the defines under nRF_Drivers are defined. You should have both NRFX_TWI_ENABLED = 1 and TWI_ENABLED = 1. Depending on what functions you use, you may also need NRFX_TWIM_ENABLED = 1. You should see in the files that have the implementations that you want to use, that they have a line close to the top saying something like:

#if NRFX_CHECK(NRFX_TWI_ENABLED)

which will return true if NRFX_TWI_ENABLED is defined to 1, and so on.

So try to include these defines in your sdk_config.h file.

Best regards,

Edvin
