Abstract

LPC11xx je porodica 32-bitnih mikrokontrolera temeljenih na Cortex-M0 arhitekturi.
Za razvoj aplikacija temeljenih na LPC11xx mikrokontrolerima koristi se razvojno
okruženje LPCXpresso. FreeRTOS je operacijski sustav u stvarnom vremenu namijenjen
radu s ugradbenim sustavima. FreeRTOS podržava upravljanje zadaćama, kao i
komunikaciju pomoću redova poruka. Demonstracijski primjer obuhvaća tri zadaće.
Prva zadaća čita podatke s analogno-digitalnog pretvornika. Druga zadaća upravlja
generiranjem PWM signala. Treća zadaća upravlja I2C komunikacijom. Putem I2C
sabirnice primaju se naredbe za upravljanje s prve dvije zadaće, a očitanje s analogno-digitalnog pretvornika se putem I2C sabirnice šalje vanjskom sklopovlju.

Abstract (english)

LPC11xx is a family of 32-bit micro controllers based on the Cortex-M0 architecture.
Applications are developed using the LPCXpresso development environment.
FreeRTOS is a real-time operating system intended for use with embedded systems.
FreeRTOS supports task scheduling, as well as communication using message queues.
The example consists of three tasks. First task is used for reading from the analog-to-digital converter. Second task manages PWM signal generation. Third task manages
I2C communication. Commands for the first two tasks are received using the I2C
bus, and the reading from the analog-to-digital converter is sent to the external devices using the I2C bus.
