DemoKit-LF3 User’s Manual
11. Sample Projects
Each of the sample programs is located in a single directory, called the main directory in each sample.
This main directory contains the complete project, inclusive of all output files of the development tool. The
78K0_LCD_DEMO.prw workspace file is located on top of the sample program directories. All sample
programs use the same directory structure.
Table 23. Example directory structure
The main directory contains most project files for the PM Plus. All source files are located in the directory
/source and the /inc directory contains the header files.
11.1 Buzzer sample
This demonstration program drives the buzzer using the 16-bit 00 timer/event counter. The timer is
configured to generate a rectangle waveform. By changing the timer’s output frequency, you can have the
buzzer generate different tones. As demonstration, the buzzer plays a simple melody.
11.2 Kitchen Timer sample
Kitchen timer functionality is realized using the real-time counter and interrupt interval function. The
setting of the kitchen timer’s count value and the cancellation of a started count process can be done
using the navigation switch. When the timer’s count time elapses, the LCD displays the alarm symbol and
the buzzer sounds an alarm.
11.3 Real-Time Clock sample
This sample project realizes a real-time clock. The program initializes the real-time counter to generate
an exact clock reference based on the 32.768 kHz subclock and displays the actual time on the LCD. You
can then use the navigation switch to adjust the time or switch between AM and PM in 24-hour mode.
11.4 Remote Control sample
The remote control sample uses the DemoKit’s IR receiver module. For this program, connect the
receiver’s IR output terminal to the microcontroller’s P41/KR1/RIN remote control input pin. The program
can then be executed to receive NEC Electronics-formatted custom code and data transmitted by an
external remote controller. The LCD will display the received data 16-bit wise.
