PIC16F690上接LCD 1602A的显示驱动



Set these pins to outputs:



PORTC: RC0 -> PIN 11 (DATA, DB4)

　　RC1 -> PIN 12 (DATA, DB5)

　　RC2 -> PIN 13 (DATA, DB6)

　　RC3 -> PIN 14 (DATA, DB7)

　　RC4 -> PIN 6 (E)

　　RC5 -> PIN 4 (RS)

　　

LCD: PIN 5 (R/W) -> Gnd (Or connect to RA0 if you want to read from LCD, not used in this lab)





Power: Pin 1 --> Gnd

　　Pin 2 --> Vcc

　　Pin 3 --> Contrast: Potentiometer center (10kohm, so you can vary voltage between 0-5V to this pin)-LCD_1602A display driver
