https://devzone.nordicsemi.com/f/nordic-q-a/18949/i2c-driver-problemI am using PCA10040 evaluation board to test I2C connection. I tried twi_scanner sample code in SDK 12. I wired SCL and SDA pins to D0 and D1 to a PicoScope device. When the code was running, I captured signals from those two pins. en-USTelligent Community 13Fri, 13 Jan 2017 03:23:16 GMThttps://devzone.nordicsemi.com/thread/73237?ContentTypeID=1Fri, 13 Jan 2017 03:23:16 GMT137ad170-7792-4731-bb38-c0d22fbe4515:31fc785e-6566-4da3-ae95-a5752756e732djqtsg<p>Hi,</p> <p>forget this question.</p> <p>The strange signal most likely is caused by PicoScope or my not properly using it; because even when I2C was working, I also captured funny clock and data signal.</p><div style="clear:both;"></div>
