4 user LED’s wired to MCU ports.
2 user pushbutton switches wired to MCU ports.
Hexadecimal encoded switch wired to 4 MCU ports.
Simple potentiometer connected to analogue input channel.
2.1. Differences to the Customer EVB
Note that the GPIO pins used for peripherals on the LCEVB are the same as those used on the
customer EVB. This ensures maximum code compatibility between the 2 boards, making it easy to
migrate from one board to the other
