How to Start Programming for ARM7 Based LPC2148 Microcontroller

The pins 2 to 15 in the Port 1 is not available for the user. Frank Donald is an Electronics and Communication Engineer who loves building stuff in his free time. I would appreciate if you provide a bare minimal sample blink led circuit with all components and programmer connected. Each pin can have multiple functions. It would be perfect if you buy a development board where you will be provided with all tutorjal software you required to code and program the chip.

Y where X stands for port number, 0 or 1 where else Y stands for pin number 0 to Love it i always thought of learning ARM and this tutorial made ma first step towards it.

This Code is only visible to Registered users. So if you want to make the whole port to function as GPIO you can simply do it by. How to do that, just go through the previous article. Tutoriall following two tabs change content below. Ports are named as P0 and P1. This huge amount of memory is well suited for almost all the applications.


Group all Htabs ARM.

When coming to ARM7 Programming there are 5 things you need to be get familiarize with. Quote and Order boards in minutes on: Now let me tell how to configure this register to force the pin to perform a specific task. You can do it by following two methods. Deva, I will try to add more tutorials and projects, thank you for your feedback.

This memory may be used for both code and data storage. Once the use of above all registers is perfectly understood, you are good to go with programming.

I hope it helps. Aside from that here are some features which makes it really unique. This register controls the state of output pins. Writing ones produces lows at the corresponding port pins and clears the corresponding bits in the IOSET register.

Notify of all new follow-up comments Notify of new replies to all ttutorial comments. Port 0 has 32 pins P0. Now you know that these registers are used to assign functions for all the Pins in the controller. 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.

ARM7 LPC2148 Tutorials

For example you have connected a switch as input to the Pin P0. We have given the most basic option for you. You can write this program using various techniques. Its fair to say that the usage of these Controllers crosses the horizon since it was used in space too.

I hope you understand it well, feel free to ask if you have any queries. SPI Module of Arduino. 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.


A 32 bit register which is used to select the function of the pins in which the user needs it to operate. This article is about how to start programming for LPC micro-controller. Interface SD Card with Arduino. It may be accessed as 8-bits, bits, and bits. Now, using the steps given here, try to program on your own and once it is done, compare with the basic program given here. Sorry it was my fault when I posted the comment.

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 code was built using Keil uvision 4 Software.

Where can I get tutorial on ARM7TDMI?

If you need to make the same pin P0. Consider the Pin P0. All the readers are supposed to write this program in specific software. For example if you need to specify P0. So the above table will give you the values you need to load to make the pin to perform your desired function.

I definitely need 10 or more articles to discuss about the highlights of ARM 7 Microcontrollers. Its ok, i figured it was a typo.
