RPi with an Oscilloscope and Java Embedded: Ready for Benchmarking (Part 2)
By Hinkmond-Oracle on Mar 08, 2013
You now have your PicoScope or your extravagant logic analyzer with oscilloscope, and you're ready to hook it up to your Raspberry Pi to measure your Java app. It's pretty straight-forward.
Attach your scope probe (refer to your documentation for your specific oscilloscope), then find an open GPIO pin that you'll use. I'm going to use GPIO24 which is Pin #18 on the header (see diagram below).
The easiest way to do this is to take a male/female jumper wire (See: link) and connect the female end to Pin #18 (GPIO24) and the male end to the probe hook (See: top photo).
That's it. You're connected now to use your scope. Next we'll take a look at different Java Embedded apps to drive the GPIO24 pin and start to benchmark the different approaches...
