https://devzone.nordicsemi.com/f/nordic-q-a/14276/how-to-test-the-oscilloscope-i2cHi there. I&#39;m woking with sensor in board nRF51822. Do we have any tool to test oscilloscope i2c? I want to check the signal is same as what I sent or not.

You can even tell the analyzer what protocol you are debugging and it will display relevant information about the transmissions. If you just have an oscilloscope I guess it is as easy as hooking the ground clips to ground on your board, and the probes directly onto the SDA and SCL lines? The guy asking questions in <a href="https://devzone.nordicsemi.com/question/66606/nrf51-and-mpu6050-twi-issue/">this thread</a> uses an oscilloscope, while you can see a trace recorded with a logic analyzer in the comments.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/54489?ContentTypeID=1Fri, 03 Jun 2016 04:55:05 GMT137ad170-7792-4731-bb38-c0d22fbe4515:6dc95d1a-52b0-4d56-acf7-f64ad4a9d121Hani Abidi<p>Hi Quinn,</p> <p>You can probe the I2C (SDA and SCL) lines with an oscilloscope or a logic analyzer to check your data.</p> <p><a href="https://www.saleae.com/">https://www.saleae.com/</a></p> <p>The logic analyzer for Saleae comes in very handy during debug.</p> <p>Hani Abidi</p><div style="clear:both;"></div>
