 +===== To Code With C =====
 +
 +Using "Geany" - an IDE which is installed and comes with Raspberry Pi. It is a GUI app, but can run it remotely from Windows via vnc server.
 +
 +**On Raspberry Pi**
 +
 +  * Run ''vncserver''
 +  * ''vncserver :1 -geometry 1920x1080''  to set up a larger window.
 +
 +**On Windows**
 +
 +  * Run VNC Client. Connect to pi 192.168.0.8. Login with "pi" credentials (regular ssh login).
 +  * You can see the GUI. Launch Geany
 +
 +===== Trying VisualGDB =====
 +
 +[9/21/2019] Because I'm doing more programming for the Raspberry Pi, decided to try VisualGDB. This is a go-between which lets you develop in Visual Studio C++, and then build/run on Raspberry Pi.
 +
 +  * https://visualgdb.com/download/
 +
 +After reviewing some of this, it is very complicated. Trying to use Geany instead on the Raspberry Pi. The code for this is not that involved.
