+README lcd-serial
+-----------------
+
+This example sets up the LCD display on the DISCO board
+and shows some sample screens. It uses some graphics code
+that was inspired by AdaFruit graphics library. Not that
+a lot of it is used but once the display was "on" it was
+something to use to put something other than straight
+lines on it :-). 
+
+It is a bit more complex because there are a lot of things
+going on at the same time. First the display is connected
+to the CPU via an SPI port. Second, the display is, like
+most LCD displays, a fairly complex controller chip in itself
+so it generally has a fairly complex initialization sequence.
+And finally, once initialized, drawing something other than
+straight lines involves a bit of bit fiddling.
+
+Once it is set up the initialization routine writes a pattern
+of lines in the RAM used to hold a frame and puts it on the
+LCD.
+
+Pressing a key will clear the screen and fill it with a box
+that has a simple text message in a box and 3 circles along
+the bottom.
+
+Pressing any key again, will bring up a display that says
+"PLANETS!" and animates three planets orbiting a star (not
+to scale :-) to give you a feel for the "speed" of animation
+when you're dumping the entire screen through the SPI port
+each time to update the display. The next example uses
+the TFT interface of the chip to load the data into the 
+display.
