Potentiometer

A single-turn potentiometer is connected as a potential divider to analog input ANI0 (Port P20, Pin 41).
The potentiometer is fitted to offer an easy method of supplying a variable analog input to the microcontroller. It does not
necessarily reflect the accuracy of the controller's ADC. Refer to the device User's Manual: Hardware for further details.

Pmod™

A Pmod™ Compatible debug LCD module is supplied with the RSK, and should be connected to the PMOD1
header.
Care should be taken when installing the LCD module to ensure pins are not bent or damaged. The LCD module is
vulnerable to electrostatic discharge (ESD); therefore appropriate ESD protection should be used.
The
Digilent Pmod™ Compatible header
display, others will have a colour display. Code for the appropriate display will be included in the product
software support. Connection information for the
Table 5-5 below.
Please note that the connector numbering adheres to the Digilent Pmod™ standard and is different from all
other connectors on the RSK designs. Details can be found in the Digilent Pmod™ Interface Specification
