The bitstream is based on Example PlatformA and the
LED7SegsTest_ecp2 project. The LED7SegsTest_ecp2.mem
and LED7SegsTest_ecp2.bit files are included in the
LED7SegsTest_ecp2 project.
Visual indications of operation are:
• Left to Right and Right to Left scanning of the 8 LEDs.
• Upcount and roll over of the 7 segment displays from 0 to 99
