the Atmel ATtiny microcontrollers.</quote> It is also the name of a 'reference
circuit' using the ATtiny2313.
</para>
<para>
The reference circuit features an IR receiver for remote controls and a LCD.
Due to hardware limitations of the ATtiny2313 the LCD does not have switchable
backlight, adjustable contrast, any keys, nor does it support displays with
more than one controller. If you want these features and do not require the
IR receiver we recommend to take a look at the <link linkend="hd44780-lcd2usb">LCD2USB</link>
