    This might be worth deepper inspection..

    I'm sorry I didn't identify the problem clearly-basicly LCDout works just fine. LCD-display can be used only for testing purposes cause it's so damn slooooow.. o:-) That's why all lcd-routines are normally bypassed by "naytto" input signal. Only problem is that if I want to use LCDout for testing, it will shut down (low) portD.7 output (MAGN) as well.. There cannot be hardware problem cause in next line I put pulsout portD.7,65530 command for testing purposes and it will flash Led in portD.7 but I cannot understand why in previous line command portD.7=1 (Magn=1) will NOT illuminate the same led.. (see line marked in RED=near lines 145 and 182)
