Hi friends,
kindly i don't know exactly where is the problem ,could you help me , i admit that am not good in electronic ,thus
in isis professional work fine with hex but when i implement it as a hardware not work
in the attached code + block diagram
and the power supply that i use +5 from phone charger or sometimes from USBport
this is code
unsigned short int kp,PWD = 0;
// Keypad module connections
char keypadPort at PORTD;
// End Keypad module connections
// LCD module connections
sbit LCD_RS at RB4_bit;
sbit LCD_EN at RB5_bit;
