 Question 1: 
 My IIC configuration is as follows 
 
 I call this function to read and write IIC 
 
 Now encountered such a problem: if I only configuration, namely just call twi_master_init initialized to the IIC, but no IIC bus communication</description><dc:language>en-US</dc:language><generator>Telligent Community 13</generator><lastBuildDate>Tue, 30 Oct 2018 14:42:40 GMT</lastBuildDate><atom:link rel="self" type="application/rss+xml" href="https://devzone.nordicsemi.com/f/nordic-q-a/39891/on-the-power-consumption-of-spi-bus-and-iic-bus" /><item><title>RE: On the power consumption of SPI bus and IIC bus</title><link>https://devzone.nordicsemi.com/thread/155176?ContentTypeID=1</link><pubDate>Tue, 30 Oct 2018 14:42:40 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:f69000b5-8489-4def-bbf4-6198cfcde849</guid><dc:creator>Stian R&amp;#248;ed Hafskjold</dc:creator><description>&lt;p&gt;Sorry, I&amp;#39;m not able to reproduce the high consumption you are seeing. Can you please post a hex file, containing simple code which will reproduce the issue? Then I can try it out here. Which hardware are you working on?
