digits?it looks i cant point over the low memory locations,i give the timing
through parallel port checking it by logic state analyzer,..........no way,i
can send data,but they only affects symbols on the first and second
digit(the lcd works,during turning on all the digits shows some symbols,that
i can erase cleaning memory)
