One point to note...
If you plug an LCD into an already powered up QCX, then your LCD will show the dreaded row of black blocks. This is not a fault. This is just because the LCD requires a certain initialization sequence, which is executed by QCX at power-up. So if you plug in an LCD module afterwards, it hasn't had the initialization sequence and it just does nothing. So remember, when re-connecting the LCD module, you need to power-cycle the QCX.
