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.
LCD (Liquid Crystal Display)
Liquid Crystal Display also called as LCD is very helpful in providing user interface as well as for debugging purpose. A liquid crystal display (LCD) is a flat panel display that uses the light modulating properties of liquid crystals (LCs). LCD Modules can present textual information to user.
The circuit and Pin diagram shows how to interface the LCD to microcontroller. The 2x16 character LCD interface card with supports both modes 4-bit and 8-bit interface, and also facility to adjust contrast of LCD through trim pot (R1).
In 8-bit interface 11 lines needed to create 8-bit interface; 8 data lines (D0 – D7), three control lines, address bit (RS), read/write bit (R/W) and control signal (EN).
In 4-bit interface 7 lines needed to create 4-bit interface; 4 data line (D0 – D3), three control lines, address bit (RS), read/write bit (R/W) and control signal (EN).
