My LCD is working. It’s awesome for the special interface I need. But I’d like to switch back and forth between a big HDMI screen and the little LCD.
Is the quickest way to do that with 2 separate MicroSD cards?
Or can I just comment/uncomment a couple of lines used to setup the LCD?
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?
I did a test and I got the same results. It is a problem with Java.
I assume you are using Ardiuno from the apt-get repo. I was… this is an old version.
I was able to download 1.6 and it worked on PiScreen
download Arduino for ARM from arduino.cc, the version i downloaded was arduino-1.6.11-linuxarm.tar.xz
-extract tar xvf arduino-1.6.11-linuxarm.tar.xz
-go into the new directory and run install.sh sudo ./install.sh
-now try and run Arduino on PiScreen… it should open, but the window is too big.
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.
