LatticeMico32/DSP Development Board
The bitstream is based on Example PlatformA and the
LED7SegsTest project. The LED7SegsTest.mem and
LED7SegsTest.bit files are included in the LED7SegsTest
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
decimal at ~1 second intervals.
Backlight is off.
Not set to any specific level.
Logic 0 on selected pins - see Table 18.
Set to below DDR400 memory use.
