BUFFER AMPLIFIER

An electronic circuits whose primary function is to connect a high-impedance source to a low-impedance load without significant attenuation or distortion of the signal. Hence, the output voltage of a buffer replicates the input voltage without loading the

ARM : Example Setting PLL for LPC2148

Hi friends this is Partha, this is my second tutorial on zembedded.com. Thanks for appreciating my first tutorial here. In this tutorial we are going to talk about clocking the ARM microcontrollers. ARM controllers can be clocked in different ways, using external clock with cycle 50-50, connecting external crystal oscillator, there are several clocking mechanism. Today we are going to discuss about using external crystal with on chip PLL oscillator.

Cortex-M3: Operation Modes & Access Levels

Thanks for the response you guys have shown in earlier tutorials on Cortex M3 series of microcontrollers. As I always request you, please check the data sheet or user manual for thorough and deep knowledge of NXP ARM controllers. NXP provides a solid documentation and example code support to all their microcontrollers.

ARM : GPIO ( General Purpose Input Output Register )

What are GPIOs??

ARM is 32-bit architecture. And that provides 32 bit GPIO ports.  In this tutorial, we are going to cover about GPIO pins, how to use them, GPIO registers and an example how microcontroller can interact with outside world with GPIO pins? For this tutorial I am just taking LPC2129 as reference and with the use of CMSIS library and explaining a few lines of code in this tutorial (want to know about CMSIS ??)

NXP offers emWin free with ARM Microcontrollers

First of all I would like to say sorry as I am sharing very old news, but still I think there are few people who are yet to explore this opportunity from NXP and Segger. Following article is from NXP site I request all the talented guys there instead of adding hours of time to write a GUI, NXP offers a great deal with ARM microcontrollers.
