Let’s learn how to Program I2C in LPC ARM7 Microcontroller. Also we will interface serial EEPROM 24LC to LPC Microchip. We will test EEPROM . Tutorials /; Creating & Debugging a Project in KEIL using ARM7 The ARM7 ANSI Optimizing C Compiler creates re locatable object modules from your C. This article is about how to start programming for LPC micro-controller. For the new reader, it is more important to have basic knowledge of pin.

Sorry it was my fault when I posted the comment. So if you want to make the whole port to function as GPIO you can simply do it by. As i said before go through the bit wise operations in C language then this will be a piece of cake.

How to Start Programming for ARM7 Based LPC Microcontroller | EngineersGarage

Y where X stands for port number, 0 or 1 where else Y stands for pin number 0 to This register controls the state of output pins. This Register is meant to clear the pins in the Ports where writing 1 will clear the respective pin while 0 will have no effect in the Ports. This Register is meant to set the pins in the Ports where writing 1 to it will set the respective pin while 0 will have no effect.


For any of the other use, programmer mustconfigure it properly. Now tutoriap know that these registers are used to assign functions for all the Pins in the controller.

The current state arm7ttdmi the GPIO configured port pins can always be read from this register, regardless of pin direction.

Video games, blogging and programming are the things he loves most.

ARM7 LPC2148 Tutorials

The following two tabs change content below. Notify of all new follow-up comments Notify of new replies to all my comments.

Choosing Motor For Robots. You can write this program using various techniques. Can you feel the difference between these two, writing 1 to the 0th position make it work as TXD and to the 1st position arm7temi it work as PWM1 as shown in the above table. If you need to use specific pin P0.

– ARM7 Tutorials – Introduction to ARM7 Architecture

This register individually controls the direction of each port pin. Pin Diagram of LPC SPI Module of Arduino. What makes this controller so special?

This huge amount of memory is well suited for almost all the applications. All the readers are supposed to write this program in specific software. Group all Htabs ARM. Interface GPS with Arduino. Each pin can perform alternate functions also.

The pins 2 to 15 in the Port 1 is not available for the user. Skip to main content. It may be accessed as 8-bits, bits, and bits.

Writing ones produces highs at the corresponding port pins. If you need to make the same pin P0. Writing ones produces lows at the corresponding port pins and clears the corresponding bits in the IOSET register. Writing zeroes has no effect. Latest uttorial by Frank Donald see all. What is Web Browser. Kindly note that loading values in IODIR, it will take effect only if the Pins are used as GPIO and the directions are controlled automatically if it was specified with any special functions.


It would be perfect if you buy a development board where you will be provided with all the software you required to code and program the chip. The tutirial is given below. I definitely need 10 or more articles to discuss about the highlights of ARM 7 Microcontrollers.

This article is tutoiral how to start programming for LPC micro-controller.

You may use it as input by loading 0. Now let me tell how to configure this register to force the pin to perform a specific task. But always mention it for good programming practice. Here is the pin diagram of LPC It will not arm7ydmi other pins. To answer this, we can point out its Robust Architecture and high computing power.
