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.

The micro slot sensor integration module continues along its path. Today I integrated the Linux operating system and TFT display onto the micro slot module base station mockup. It was a beast to get it integrated and set up. Still not fully calibrated yet.

The point is to bring an integrated touch-sensitive display onto the single board computer platform which hosts the various sensor ports and micro slot module I made just a week or so ago.

It will take tethered sensor readings and read those back to a viewer. It will provide an input path via mouse and keypad in addition to the touch screen.
