8.1 Display Board
8.1.1 Description of display board
General description
The display board has three major parts : the LCD (Liguid
Crystal Display), the display controller and the
keyboard.
The display controller is controlled by the DASP master
processor on the CDR main board. The communication
protocol used is I2C. So all the information between DASP and
display controller goes via the SDA or I2C DATA and SCL or
I2C CLK lines. Communication is always initiated by the DASP
on the CDR main board. Unlike the previous generations of
CDR players, the interrupt generated by the display controller
at key-press or reception of remote control is not used. Instead,
the DASP polls the display controller for these events.
