RPi and TFT Touchscreen Set Up, Programming & Calibration

Today I finished the Linux upgrades, updates, and corresponding TFT calibration. Via puTTY and over WiFi, it took 2-days of continued remote server code query, download, transfer, extraction, and installation onto a 32GB microSD Linux O/S. No exaggeration.

This is what it took to get the monitor calibrated and aligned from a Linux Jessie config file.

Very pleased with the outcome of the touchscreen. Moving on to the sensor station’s schematic capture, PCB layout, and fabrication.
