    lcd16x2 data lines with shifting bits

    hi, i am working on 16x2 lcd with 4bit mode on pic18f. my connections are as follows : RS -RA5 E - RA4 D4 - RA3 D5 - RA2 D6 - RA1 D7 - RA0 so my shifting bits are as follows : /* First nibble */ E_BIT_HIGH; // E to HIGH udelay(2); // Write data LATA = ((LATA & 0x0F) | ((cmd &...
