9. 9 © 2010 Renesas Electronics America Inc. All rights reserved. Agenda R8C/Lx MCU overview The R8C LCD API Hands-on Lab – 30 minutes Q&A

10. 10 © 2010 Renesas Electronics America Inc. All rights reserved. Question: ? Have you done a design using segment LCD’s, and found that it wasn’t anything like the last one you did? Did you have to start over doing LCD mapping software because the MCU, the LCD or both have changed? If you answer YES to either of these questions, then the LCD API solution we present today is for you!

The custom_lcd.h file The custom_lcd.h file is where the LCD physical interface is defined to the API software: LCD pins are assigned to MCU pins to match your schematic Icons are each assigned a name LCD SEG/COM pins are mapped into the software per your LCD drawing Take a few minutes to look at the custom_lcd.h file during the lab.

21. 21 © 2010 Renesas Electronics America Inc. All rights reserved. Start the Lab Keep your dice turned to the section of the lab you are on. (Instructions are provided in the lab handout) Please refer to the Lab Handout and let’s get started!

22. 22 © 2010 Renesas Electronics America Inc. All rights reserved. Checking Progress We are using the die to keep track of where everyone is in the lab. Make sure to update it as you change sections. When done with the lab, your die will have the 6 pointing up as shown here.
