The Basics After writing the first blinky program using random delay , now its time to improvise and induce precise delay using timers! The real fun in embedded starts when you start playing with timers (& UARTs , PWM , etc.. ofcourse which we will see in my future posts). I’ll try to keep it [...]
Many guys including me have been facing a problem with KEIL4 where the Interrupts or IRQs wont execute even if the code is correct .. but now I’ve found a simple trick to make the interrupts work. Even I have wasted a long time trying to figure out what the heck was going wrong with [...]
On special request of our readers today we are posting a new tutorial for interfacing HD44780U / KS0066U based 16×2 LCD Module with LPC2148 microcontroller.
Introduction PLL stands for Phase Locked Loop and is used to generate clock pulse given a reference clock input which is generally from a crystal oscillator(or XTAL). Configuring and using PLL in lpc124x MCUs is pretty simple and straight forward. Lpc214x MCUs have 2 PLL blocks viz. PPL0 and PLL1. PLL0 is used to generate [...]
When getting started in embedded programming, GPIO (viz. General Purpose Input Output) pins are one of the first things played with. Its also quite evident that the most popular “hello world” program in embedded systems programming is Blinky i.e a LED connected to pin on the Microcontroller that keeps blinking. The use of GPIO is [...]
