  • Reseting uLCD-70DT via host PIC 18F4685

    Want to use Port C6 on the PIC 18F4685 to reset the uLCD-70DT, the data sheet states a low for 2us, it then has to be brought high, as the PIc is running at 5 volts this would apply 5 volts to the reset pin, is this OK? The data sheet states it is internally pulled to 3.3 volts. The PIC data sheets states the C6 port is "CMOS compatible input or output". Is this OK

    The reset pin is 5v Tolerant, so you will be fine
