Mark, thank you! I struggled a bit, but in the end it's all working, thanks to your encouragement!
I like the little LCD touchscreen on my RPi3. My Arduino sketches are easy to see, and they work great.

To be very specific, I want to use the Arduino program to send sketches to the Arduino UNO connected to the USB. But the LCD shows a completely white screen when I launch Arduino. Sure, I can run load or write a sketch, upload it to the UNO, and control the UNO with Python when connected to HDMI, but to reboot for the LCD, I'll lose my serial connection. Anyone experience this?

Thanks, Mark, for the response. Actually, I assumed PiScreen (not PiScreen2r), and it works, for the most part. The touch was working, and the touchscreen calibration tool seems to work, but with the keyboard and mouse plugged in, the touch is not working. Step by step, I'll get there.
