undeclared identifier TWI0_USE_EASY_DMA error - still occurringhttps://devzone.nordicsemi.com/f/nordic-q-a/19148/undeclared-identifier-twi0_use_easy_dma-error---still-occurringHi, I have been receiving the error: undeclared identifier &quot;TWI0_USE_EASY_DMA&quot;. I researched and found that the solution was to include &quot;nrf_drv_config.h&quot; and add #define TWI0_ENABLED 1. However, I am still receiving the error. I do get a warning sayingen-USTelligent Community 13Fri, 27 Jan 2017 07:46:58 GMTRE: undeclared identifier TWI0_USE_EASY_DMA error - still occurringhttps://devzone.nordicsemi.com/thread/74106?ContentTypeID=1Fri, 27 Jan 2017 07:46:58 GMT137ad170-7792-4731-bb38-c0d22fbe4515:33edda34-7e0a-4c26-ab0b-439d6e7d237fJ&#248;rgen Holmefjord<p>Great that you got it working, happy to help!</p><div style="clear:both;"></div>RE: undeclared identifier TWI0_USE_EASY_DMA error - still occurringhttps://devzone.nordicsemi.com/thread/74105?ContentTypeID=1Thu, 26 Jan 2017 19:08:36 GMT137ad170-7792-4731-bb38-c0d22fbe4515:bc7bb9b7-6ec9-42d8-926d-195f94035e3cLevi<p>Hi Jørgen,</p> <p>I finally got back to this project.

You should confiure the TWI peripheral using the <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v12.2.0/sdk_config.html?cp=4_0_1_1_6">SDK configuration header</a>, <em>sdk_config.h</em>.</p> <p>Depending on which example you started from, you might have to copy the configuration for TWI into your <em>sdk_config.h</em> file. You can find the relevant configuration for TWI on line 2589 - 2722 in <code>[SDK_ROOT]\examples\ble_peripheral\ble_app_template\pca10040\s132\config\sdk_config.h</code>.</p> <p>Best regards,</p> <p>Jørgen</p><div style="clear:both;"></div>RE: undeclared identifier TWI0_USE_EASY_DMA error - still occurringhttps://devzone.nordicsemi.com/thread/74102?ContentTypeID=1Mon, 23 Jan 2017 12:28:35 GMT137ad170-7792-4731-bb38-c0d22fbe4515:4d887b30-eff3-4737-bf14-bc6525c329d7Levi<p>I am using NRF5 SDK 12.2 from 6 December 2016.
