The ARM9-LPC2929 STICK BOARD is specifically designed to help students to master the required skills in the area of embedded systems. The board is designed in such way that all the possible features of the microcontroller will be easily used by the students. The board supports Keil µVision 4 compilers with Keil ULink2.
NXP Microcontroller, ARM9-LPC2929 stick board is proposed to smooth the progress of developing and debugging of various designs encompassing of speed 32-bit Microcontrollers. It integrates CAN, LIN, UART, ADC, PWM, I2C, SPI, Timer, Interrupt etc., to create a stand-alone versatile test platform.
ARM9 Stick Board having more no of I/O line for user access able. Its consists of 64 GPIO pins, CAN0/1, LIN1, I2C0/1, UART0/1, SPI0/1, USB, ADC0/1/2, PWM, Timer and more features. Users can easily access the controller and develop more application by using ARM9 Stick board.
Light Emitting Diodes (LED) is the most commonly used one component, usually to display the pins digital states. Typical uses of LEDs include timers, alarm devices & confirmation of user input such as a keystroke or mouse click.
Figure shows how to interface the LED to microcontroller. As you can see the Cathode is connected through a resistor to GND & the Anode is connected to the Microcontroller pin. So when the Port Pin is HIGH the LED is ON & when the Port Pin is LOW the LED is turned OFF.
