NP1 LPC21XX/LPC22XX microcontroller implementation

This course covers NXP ARM-based MCU family

formateur
Objectives
  • The course details the hardware implementation of the LPC2294 microcontrollers.
  • The boot sequence and the clocking are explained.
  • The training helps to become familiar with the development environment chosen by the customer.
  • Practical labs on integrated peripherals are based on I/O functions provided by NXP.
  • The course focuses on the low level programming of the ARM7TDMI core.
  • The course provides examples of internal peripheral software drivers.

  • Note that ACSYS does not sell emulation probes and IDEs. Consequently this course has not been designed to convince attendees to buy a particular IDE. The unique objective consists in providing sufficient knowledge to attendees so that they can successfully design a system based on LPC21XX/LPC22XX.

  • This course has been delivered several times to companies developing embedded systems, such as voltage counters.
A lot of programming examples have been developed by ACSYS to explain the boot sequence, the vector table and the operation of embedded peripherals.
•  They have been developed with 2 different IDEs : Keil and IAR.
•  Consequently for on site course, it is up to the customer to select the IDE under which labs will be run.
