Lcd code for pic24f16ka102 and lcm-s01602dtr m

[adnan012]

HI

i want to interface PIC24F16KA102 AND LCM-S01602DTR M.

The code runs on proteus simulation but not on hardware.

i want to use port b for 8 bit data and control pins. what is the correct way of writing data and control signals on same 16 bit port.
