I. Abstract
The aim of this experiment is learning about how to communicate with the
TMS320C5515 kit, how to use Charset editor software to get the code of each character.
Study the sample code to learn how to program the code for the kit's screen to display
the required requirements. After this experiment, we better understand and how to
program the kit to explore more advanced features of the kit.

II. Introduction
- Introducing oled LCD of TMS320C5515/35 and implementing the display on oled LCD.

- LCD of TMS320C5515/35 is a 96x16 OLED display screen which has 96 columns and 16
rows. The display screen is divided into two regions, so actually we have two 96x8 to
display a text.
- For this project, to illustrate each character, we need 5x8 pixels. To keep the space
between characters, we use only 4x7 pixels for designing. Each led in LCD is activated by
setting to bit 1. The picture below will clearly show the rules of writing on LCD.

Fig 1. How to define a character in LCD.
- In project sample lcd-osd9616, to print out a character, they implement a function
called printLetter.

V. Conclusion
- After doing the experiment, we understand how the TMS320C5515 kit working. We
also know how to write each character by using the Charset editor on the LCD led and
the requirements that we have to follow are how the characters are built and also its
aesthetic when we display on the LCD led.
-On the other hand, this laboratory requires us the patience when building the character
for a better displaying on the LCD led so our group spend most of the time figuring out
the mistakes on the sample code which is provided by the instructors and we can not be
able to finish the whole task on time and we still missing some characters in the task.
- We have to manage our time more logical in order to finish the provided task on time
and the results we gain is the best and the most optimal one.
