Week12-13

 
During these two weeks I made the gradual progress in developing the firmware of the OLED and
the basic functions of character display and graphic display can be shown on the screen.
As the two pictures shows above the first one is some simple graphic display and the second one is text display as well.  for the text display, each line can display max 12 characters  and there are totally 6 lines. So the screen can display totally show 72 character each time. However, for the animation display it is a bit hard for using this one because we need to interface the extra memory to store the data and wirte the code for the animation ourselves.
 
Totally the sketch of  26 capital letter and 26 lower case and 20 symbols and the character display function is highly intergated into a single function, which can display charater or symbols by passing ASCII code to the function.
