LED Add-On Board
Description
Add-on board compatible with the Gecko4 main only.
This is a board for performing different digital exercices.
Inputs:
- 1 dip switch 8 poles
- 6 push buttons
- 2 joysticks 4 ways with a center push.
Outputs :
- 64 LEDs array (32 green LEDs and 32 red LEDs)
- 3 RGB LEDs
- 3 seven segments
With Logisim (version with the FPGA Commander) you can easily create a circuit and then load it on the GEKO4main via USBTMC0.
If you are using the GeckoXSimple rev 1.0 you will see that the LED 8 will be on if you don't assign it to an output. With the rev 2.0 this bug is no more present.
