Test code:
// include the library code:
#include <LiquidCrystal.h>
// initialize the library by associating any needed LCD interface pin
// with the arduino pin number it is connected to
const int rs = PB12, en = PB13, d4 =PA4, d5 = PA3, d6 = PA2, d7 = PA1;
LiquidCrystal lcd(rs, en, d4, d5, d6, d7);
void setup() {
// set up the LCD's number of columns and rows:
lcd.begin(16, 2);
// Print a message to the LCD.
lcd.print("PARKING");
}
void loop() {
// set the cursor to column 0, line 1
// (note: line 1 is the second row, since counting begins with 0):
lcd.setCursor(0, 1);
}
And it is CAT6 cable, that all will go to PCB and be soldered, this untidy breadboard option is only for the testing
