-# Lights Example
-This example flashes the LEDs present on the FX2LP CY7C68013A mini board. It
-can be used for testing loading of firmware onto these boards. The expected
-pattern is D1 turning on, then D2 250ms later, then D1 off, then D2 off and the
-cycle repeats
-
-The firmware is built using `make` and loaded using `make load`, which uses the
-[HDMI2USB-mode-switch](https://github.com/timvideos/HDMI2USB-mode-switch)
-utility to load the firmware onto the FX2 chip.

-# Serial Example
-
-This serial example is for testing serial connections from the FX2 chip. It is
-uses the same setup as the HDMI2USB firmware, which is:
-
- * Baud rate of 115200
- * Serial device /dev/ttyUSB0 (default on linux)
- * Connections
-  - RXD -> PD3
-  - GND -> GND
-
-This example prints "This is the serial example for the HDMI2USB firmware" to
-the TXD pin every two seconds
-
-To build the firmware run `make`, which will pull in the required dependencies
-and build the `serial.hex` firmware image. This can be loaded using the
-[HDMI2USB-mode-switch](https://github.com/timvideos/HDMI2USB-mode-switch)
-utility, which is what `make load` uses.
-
-Under linux serial can be read using minicom. This example was tested using the
-Digilent PmodUSBUART Serial to USB adaptor.
-
-FIXME: Add minicom example.
-
-FIXME: Only the Atlys and FX2 Dev board uses bit banging, the Opsis uses the
-hardware serial.
-
-## Wiring Diagram
-
-FIXME: Use real pictures in the diagram.
