AT3 AT91RM9200 microcontroller implementation

This course covers AT91RM9200 ARM-based MCU family

formateur
Objectives
  • The course details the hardware implementation of the AT91RM9000.
  • The ARM920T operation is detailed, particularly cache and MMU.
  • The boot sequence and the clocking are explained.
  • Practical labs on integrated peripherals are based on I/O functions provided by Atmel.
  • 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 AT91RM9200.

  • This course has been delivered several times to companies developing embedded systems, such as medical equipments.

  • Note that an additional day on Linux porting onto an AT91RM9200 board may be appended.
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.
A more detailed course description is available on request at training@ac6-training.com
  • Theoretical course
    • PDF course material (in English) supplemented by a printed version.
    • The trainer answers trainees' questions during the training and provide technical and pedagogical assistance.
  • At the start of each session the trainer will interact with the trainees to ensure the course fits their expectations and correct if needed
  • Any embedded systems engineer or technician with the above prerequisites.
  • The prerequisites indicated above are assessed before the training by the technical supervision of the traineein his company, or by the trainee himself in the exceptional case of an individual trainee.
  • Trainee progress is assessed by quizzes offered at the end of various sections to verify that the trainees have assimilated the points presented
  • At the end of the training, each trainee receives a certificate attesting that they have successfully completed the course.
    • In the event of a problem, discovered during the course, due to a lack of prerequisites by the trainee a different or additional training is offered to them, generally to reinforce their prerequisites,in agreement with their company manager if applicable.
