Add Lumacode support for easy connection to an RGBtoHDMI.
After flashing the firmware, add a jumper link between pin 9 and 10 of the JTAG header and then put the mode selector switch to the right-most position (right when looking at the computer from the front side). The board then outputs a "Lumacode" signal on the luma line (green jack of the breakout cable). This can then be fed into a Lumacode-compatible RGBtoHDMI device.
Note that the "Sync" voltage level is not the same as on a regular Lumacode source because the existing electronics can not generate it, so you need to adjust this voltage in the "Sampling Menu" of the RGBtoHDMI.
