Sample Code
- buzzer/
-
This sample demonstrates piezo electric buzzer interfacing. When the
program is executed a 100Hz buzzing sound is produced
continuously. Ensure switch 1 of INTR/BUZZ DIP switch is in ON
position.
Download: for Windows for Linux - interrupt/
-
The sample demonstrates interrupt programming. The LEDs toggle
alternately on an INTR key press. Ensure that switch 3 of INTR/BUZZ
DIP switch is in ON position.
Download: for Windows for Linux - keys/
-
The sample demonstrates access of keys KEY1-KEY4. When the program is
executed, the keys are scanned and the key pressed is displayed on the
LCD.

-
This sample demonstrates LCD interfacing. When the program is executed
the string "Zilogic Systems" is displayed on the LCD, and after a
delay of 1 second, the string "Explore ZKit-51" is displayed a
character at a time, in a typewriter fashion.
Download: for Windows for Linux - led/
-
This sample demonstrates LED programming. When the program is
executed, the LEDs are blinked alternatively.
Download: for Windows for Linux - rtc/
-
The sample reads and writes to RTC (PCF8563). Ensure that the RTC data
is backed up before running this sample as it overwrites the RTC time
registers. The Low Voltage indicator flag is also overlooked for the
sake of simplicity.
Download: for Windows for Linux - serial/
-
This sample demonstrates UART communication. When the program is
executed, a string is transmitted through the serial interface, and
can be seen using a serial terminal program like Hyperterminal or
Minicom. The serial terminal program should be configured with the
following parameters: 9600 baudrate, 8 data bits, no parity, 1 stop
bit. Also note that while using a serial terminal program, the USBSIO
DIP switches 3 & 4 should be in OFF position.
Download: for Windows for Linux - spi/
-
This sample demonstrates SPI EEPROM access. When the program is
executed the number of reboots occurred is displayed on the LCD. The
reboot count is incremented when the board is reset or
power-cycled. Since on power off or reset data in RAM is lost, the
reboot count is stored in the SPI EEPROM.
Download: for Windows for Linux - timer/
-
This sample demonstrates hardware delays using 8051 timers. When the
program is executed the LEDs are blinked alternatively with a time
period of 1 second.
