hi all
i want to do a simple circuit : car parking counter
there are two IR-sensors (QRB1114) one at the entrance and the other at the exit gate ,the output are two LEDs (green and red) and 2x16 LCD if there is a place the green LED will lit and the LCD shows "there is place" and if there is no place the red LED will lit and LCD shows "no place"
i wrote my program in C language and i do the initilization
could you please let me know why the LCD is not working?
find my program in the file
thanks in advance
