7.3  Encoder

7.3.1  Encoder Input Types

There are three encoder inputs.

ENCODER_TTL - Single ended TTL level encoder
ENCODER_DIFF - Differential (LVDS) encoder
ENCODER_OPTO - Optocoupled encoder

The hardware encoder is enabled/disabled by the bit EN_ENCODER. Only one input 
at a time is active (the software encoder bit, SW_ENC, is always active). The active 
encoder is selected by the bitfield SEL_ENC. The current level of these inputs can be 
read from software by reading the bits RD_ENC_DIFF, RD_ENC_TTL and RD_ENCO-
PTO. The unselected inputs will have no effect on the board. However, they can be 
used as general purpose inputs.

7.3.2  The Optocoupled Encoder

The opto-coupled encoder allows the acquisition circuitry to accept an encoder sig-
nal without having a galvanic connection to the encoder source. This is mandatory in 
some medical and industrial application. The encoder information is passed as a light 
pulse from an on-board LED that is coupled to a receiving phototransistor. The LED 
and the phototransistor are in the same package, a Sharp PC3H711. Figure 7-2 shows 
the electrical diagram of the optocoupled encoder circuit and a suggested circuit for 
the driver. The LED is driven by an open collector driver. The user must supply his +5V 
power to the LED. Note that there is no galvanic connection between the user’s circuit 
and the acquisition circuitry.
