How to read the I2C bus on an oscilloscope?
Part 2 of Mastering the Oscilloscope will introduce decoding for I²C circuits. Oscilloscopes offer a variety of tools to help diagnose troublesome circuits. In this tutorial, we will use the oscilloscope to read an I²C serial bus.
How do you set up an oscilloscope?
Next, you’ll need to set up your oscilloscope. To do that, follow these steps: Turn on the oscilloscope and wait until it completes its self-tests. Plug probes into Channel 1 and Channel 2. Connect the probe’s ground clip to a ground point in the circuit (use a jumper wire if necessary).
How long does it take to decode an I2C bus?
In under 15 minutes, we decoded an I²C bus and, from across the room, saved the data to a computer for analysis. And now that the shared folder is established, future work can be accomplished in just a few minutes. This automatic decoding process is much more effective than simply probing the signals and trying to manually interpret logic levels.
Where is decoded data stored on an oscilloscope?
Decoded data is stored in an event table. You can save it to a USB drive or to your computer. Since plugging in a USB drive is a trivial example, we’ll do it the hard way by remotely controlling the scope. The steps below are specific to Microsoft Windows and the Tektronix MDO3000 and MDO4000 series of scopes.
Where is the IP address of an oscilloscope?
TELNET -O 192.168.0.40 4000 // Change 192.168.0.40 to the IP of your scope, displayed on the main screen at startup. You are now connected to the oscilloscope at its IP address on the default port 4000. Type the following:
How to create a share on an oscilloscope?
NET SHARE Scope=C:\\Oscilloscope /remark:”TEK3104 Data” /grant:domain\ser,FULL // This creates a share named “Scope” on your main hard drive. You can change it to any location you like.
How to insert BD-LLC between Arduino and I²C?
To insert your BD-LLC between the Arduino and your I²C device, make the following connections: Next, you’ll need to set up your oscilloscope. To do that, follow these steps: Turn on the oscilloscope and wait until it completes its self-tests.
