#123611 - Look at I2C Responding to: ???'s previous message |
If you are running low on port pins you may want to consider adding I2C and using a port expander, PCF8574, to drive your LCD and other slow (relatively speaking) devices. Since the I2C bus runs at around 1 mHz timing for the LCD should be very easy to deal with.
