This is the Revision A verion of the Line3 module. The status of this project is finished.
This document is also available in PDF format.
The Line3 module has 3 infrared (IR) sensors for sensing lines on flat surfaces. There are sensor that straddle the line and one that can detect when the line simply ends.

In addition to the common shared commands and the shared interrupt commands, the Line3 RoboBrix supports following commands:
| Command | Send/ Receive |
Byte Value | Discussion | |||||||
|---|---|---|---|---|---|---|---|---|---|---|
| 7 | 6 | 5 | 4 | 3 | 2 | 1 | 0 | |||
| Read Interrupt Bits | Send | 1 | 1 | 1 | 0 | 1 | 1 | 1 | 1 | Return the interrupt pending bit p and the interrupt enable bit e. |
| Receive | 0 | 0 | 0 | 0 | 0 | 0 | e | p | ||
| Set Interrupt Commands | Send | 1 | 1 | 1 | 1 | 0 | c | c | c | Set Interrupt Command ccc. |
| Shared Commands | Send | 1 | 1 | 1 | 1 | 1 | c | c | c | Execute common shared command ccc |
The hardware consists of a circuit schematic and a printed circuit board.
