LCD 2x40 midibox LC

Hello

I almost finished my Midibox LC, quite function(office) except the LCD 2x40

My problem of display(posting) with my LCD 2x40, is that it does not post(show) me voucher characters.

Ex: instead of posting(showing) MIDIBOX he(it) posts(shows) me LHdRBVx.

I have to test with a LCD 2x16 and no problem.

Can get clearer to me? That it is necessary to change in the code in ASM = > midibox LC

Thank you
