5.4 LEDs
There are five LEDs on the RSK. The function of each LED, its colour, and its connections are shown in
Table
5-3 .

5.5 Potentiometer
A single-turn potentiometer is connected as a potential divider to analogue input AN000, pin 60. The
potentiometer can be used to create a voltage between Board_3V3 and ground.
The potentiometer offers an easy method of supplying a variable analogue input to the microcontroller. It does not
necessarily reflect the accuracy of the controller’s ADC. Refer to the RX111 Group Hardware Manual for further details.
5.6 Pmod™ Debug LCD Module
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
uses a SPI interface. Some RSKs will be provided with a monochrome
display, others will have a colour display. Code for the appropriate display will be included in the product
software support. Connection information for the
Digilent Pmod™ Compatible header
is provided in Table 5-4
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
