The Xplain kit demonstrates how to use the External Bus Interface (EBI) module to
interface a 4-bit SDRAM. An 8MB SDRAM (16M x 4) is attached in 3-port EBI mode
(PORTH, PORTK and PORTJ).
An 8MB serial Dataflash
master mode to interface the dataflash.
Eight micro switch buttons are connected to the XMEGA’s PORTF. Internal pull-ups
should be enabled to detect when the buttons are pushed as they short the respective
line to GND.
Eight LEDs are connected to the XMEGA’s PORTE. The LEDs are active low – and
thus lights up when the respective lines are drawn low by the XMEGA.
An NTC and an adjustable resistor divider (potentiometer) are connected to PORTB
on PINB0 and PINB1 respectively. These analog references can be used as input to
the ADC.
An audio amplifier (and mono speaker) is connected to PORTB on PINB2. This pin is
connected to the XMEGA’s DAC and thus offers a way to generate sound.
A Getting-Started training for the Xplain kit can be downloaded from the Atmel web
site. This training is a general introduction to XMEGA peripherals.
Further information and drivers for XMEGA can be downloaded as application notes,
also distributed from Atmel’s web site.
