Utility Interfaces
Besides the high speed mezzanine interface connectors P-HSE1 and P-HSE2, the PC7-FESTIVAL is
provided with the utility interface expansion connector socket P-EXP. This connector comprises
several interfaces, which may be useful for system expansion on mezzanine cards, as an option:
< HD Audio
<
LPC (Low Pin Count)
<
I
2
C
<
2 x UART (TTL)
The I
2
C is connected to controller I
2
C[0] of the CM238 platform controller hub. The I
2
C signal lines
on the P-EXP utility expansion connector are also routed to P-HSE2.
The HD Audio port requires an additional audio codec, as provided e.g. on the SCS-TRUMPET side
card.
The LPC bus presents an easy way to add legacy interfaces to the system. EKF offers a variety of
mezzanine expansion boards (side cards), to be attached on top of the PC7-FESTIVAL, featuring
all classic Super-I/O functionality, for example the SCS-TRUMPET or PCS-BALLET. Access to the
connectors PS/2 (mouse, keyboard), COM, USB and audio in/out is given directly from the front
panel.
