&lt;p&gt;Are you using the TWI driver in the SDK?&lt;/p&gt;
&lt;p&gt;The TWI pins are configured on line 222 and 229 of twi_hw_master.c, and by default the internal pullups are enabled.&lt;/p&gt;
&lt;p&gt;You can change this by replacing &lt;strong&gt;GPIO_PIN_CNF_PULL_Pullup&lt;/strong&gt; with &lt;strong&gt;GPIO_PIN_CNF_PULL_Disabled&lt;/strong&gt; for both of these pins.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
