Re: QCX LPF adjustments

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.

Yes Ian you can remove the display and make adjustments to the LPF windings. This will not hurt the QCX functionality and when you re-plug in the display all should be good again.
