-====== 7 Segment Display ======
+====== 7-Segment Display ======
-There are 4 7 segment displays mounted on the CT Board. The displays can be accessed over two different interfaces:
+The CT Board provides four 7-segment displays. The displays can be accessed through two different interfaces:
-  * The [[#hex_display|binary]] interface, for HEX representation of binary values
+  * The [[7segment_bin|binary]] interface, for HEX representation of binary values
-  * The [[#segment_control|"raw"]] interface, for independent controll over each segment
+  * The [[7segment_raw|"segment control"]] interface, for independent control of each segment
 Depending on the used addresses the display will switch automatically. \\ \\
-> {{ctboard_mode_1.svg?48px }} {{ctboard_mode_2.svg?48px }} {{ctboard_mode_3.svg?48px }} Please make sure the CT Board is in the correct mode.
-> Supported modes: **1**, **2**, **3**
-===== Segment Control =====
-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.
-==== Registers ====
-The Registers are read / write.

-===== HEX Display =====
-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 [[#segment_control|raw interface]]. \\ \\
