- How to Interface GLCD with ARM9 Stick Board
ARM9-LPC2929 STICK BOARD
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.
GLCD (Graphical Liquid Crystal Display)
Graphical Liquid Crystal Display also called as GLCD. It is very helpful in providing user interface as well as for debugging purpose. A Graphical liquid crystal display (GLCD) is a flat panel display that uses the light modulating properties of liquid crystals (LCs). GLCD Modules can present graphical information to user.
The circuit and Pin diagram shows how to interface the GLCD to microcontroller. The 64x128 GLCD interface card support 8-bit interface and also have a facility to adjust contrast of GLCD through trim pot (R2).
In GLCD interface 14 lines needed to create 8-bit interface; 8 data lines (D0 – D7); Four control lines, address bit (RS), read/write bit (RW), control signal (EN) and GLCD reset (RST); Two chip select lines (CS0 and CS1).
