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.

For example ar,7tdmi have connected a switch as input to the Pin P0. Interface GPS with Arduino. I cant understand you, I guess the article is clear enough for explaining basics.

If you need to use specific pin P0. I hope you understand it well, feel free to ask if you have any queries. Latest posts by Frank Donald see all. For example if you need to Clear P0.

How to Start Programming for ARM7 Based LPC2148 Microcontroller

Ports are named as P0 and P1. All the readers are supposed to write this program in specific software. Yutorial to main content. To answer this, we can point out its Robust Architecture and high computing power.

ARM7 LPC2148 Tutorials

Its fair tytorial say that the usage of these Controllers crosses the horizon since it was used in space too. Writing zeroes has no effect. This code was built using Keil uvision 4 Software. When coming to ARM7 Programming there are 5 things you need to tutofial get familiarize with.


This article is about how to start programming for LPC micro-controller. Writing ones produces lows at the corresponding port pins and clears the corresponding bits in the IOSET register. What is Web Browser.

If any driver is also needed. Choosing Motor For Robots. As i said before go through the bit wise operations in C language then this will be a piece of cake. Blink LEDs connected on pins P1.

Frank Donald October 2, 13 Comments. Frank Donald is an Electronics and Communication Engineer who loves building stuff in his free time. Hello I am bob arm7dtmi i love your tutorial please help me get atm7tdmi very well like how to build a simple circuit using the chip and how to configure the software I KNOW OF KEIL but how to i put up a simple circuit together,crystal ,capacitors etc and what programmer do i need.

Its ok, i ar7mtdmi it was a typo. Writing ones produces highs at the corresponding port pins. Can you feel the difference between these two, writing 1 to the 0th position make it work as TXD and to the 1st position make it work as PWM1 as shown in the above table. It means that the pin can either act as a Input or Output with no specific functions.

– ARM7 Tutorials – Introduction to ARM7 Architecture

Each pin can perform alternate functions also. Once the use of above all registers is perfectly understood, you are good to go with programming. This register individually controls the direction of each port pin. What makes this controller so special? 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. So the above table will give you the values you need to load to make the pin to perform your desired function.


Love it i always thought of learning ARM and this tutorial made ma first step towards it. You may use it as input by loading 0. SPI Module of Arduino. Consider the Pin P0. How to do that, just go through the previous article. If you need to make the same pin P0.

You can write this program using ttorial techniques. The pins 2 to 15 in the Port 1 is not available for the user. The following two tabs change content below. A 32 bit register which is used to select the function of the pins in which the user needs it to operate.

But always mention it for good programming practice. I definitely need 10 or more articles to discuss about the highlights of ARM 7 Microcontrollers. We have given the most basic option for you. There are plenty of devices and gadgets running with the help of these Controllers. This high-density System-in-Package SiP integrates controller, power switches, and support components.
