Dear Jetson-Afficionados,
Jim from Jetsonhacks was so kind to point me to this location, to share my idea and code for a GPU/CPU Performance Display.
Boring! - Someone might think, as there is the great JTOP tool out in Jetson-Space. That’s true and I also make heavy use of it.
But… this time my Xavier AGX was faceless on my desk without a monitor. So let’s simply take a 0.96 OLED display with I2C, look at Jim’s pinout description on jetsonhacks.com and minutes later we know our performance figures.
Well, finally it took me a day to reach 1st results, as busio is not supported on my Tegra and I could only get slow smbus2 ‘command mode’ working.
Long story short, look at my github repo and enjoy the hack.
If you know a better way talking to the OLED, I’d be happy to optimize the code.
Happy Jetson Hacking,
-Pete
