Last week, I explained how I was able to run StreamSets Data Collector (SDC) on a Raspberry Pi 3, ingesting sensor data and writing it to Cassandra. With that working, I wanted to show pipeline metrics on Adafruit’s awesome PiTFT Plus 2.8″ screen. In this blog post, I’ll explain how I was able to write a Python app to retrieve pipeline metrics with SDC’s REST API, showing them on the PiTFT Plus via pygame.

PiTFT Plus Assembled 320×240 2.8″ TFT + Resistive Touchscreen: Is this not the cutest little display for the Raspberry Pi? It features a 2.8″ display with 320×240 16-bit color pixels and a resistive touch overlay. The plate uses the high speed SPI interface on the Pi and can use the mini display as a console, X window port, displaying images or video etc. Best of all it plugs right in on top! Read more.
