7 Segment Display

There are 4 7 segment displays mounted on the CT Board. The displays can be accessed over two different interfaces:

• The binary interface, for HEX representation of binary values
• The "raw" interface, for independent controll over each segment

Depending on the used addresses the display will switch automatically.

Please make sure the CT Board is in the correct mode.
Supported modes: 1, 2, 3

This is the “raw” interface. Each segment of the display can be controled independently. The segments are “active-low”, e.g. the segment is on if a logical “0” is written to it.

The Registers are read / write.

Additionally the display can be used as HEX display. All 4 displays can directly show a 16 bit binary value.
In this mode the display can't be switched off, use the raw interface.

The Registers are read / write.
