AT3 AT91RM9200 microcontroller implementation

This course covers AT91RM9200 ARM-based MCU family


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.
