undeclared identifier TWI0_USE_EASY_DMA error - still occurring

[Levi]

Hi,

I have been receiving the error: undeclared identifier "TWI0_USE_EASY_DMA". I researched and found that the solution was to include "nrf_drv_config.h" and add #define TWI0_ENABLED 1. However, I am still receiving the error. I do get a warning saying: "'TWI0_ENABLED' macro redefined".

I am new to using Keil and I am unsure if I am doing something wrong. I have already fixed a few compiler issues and I'm wondering if that's the case here. Does anyone have input?

Thanks!

Which SDK verison are you using?

I am using NRF5 SDK 12.2 from 6 December 2016. Thanks for the help.

nrf_drv_config.h is no longer used from SDK 12.0.0. You should confiure the TWI peripheral using the SDK configuration header, sdk_config.h.

Depending on which example you started from, you might have to copy the configuration for TWI into your sdk_config.h file. You can find the relevant configuration for TWI on line 2589 - 2722 in [SDK_ROOT]\examples\ble_peripheral\ble_app_template\pca10040\s132\config\sdk_config.h.

Best regards,

Jørgen
