Greetings! I have just started playing with the Arduino - did a few projects with C and PIC's about 20 years ago. My question is about overhead using serial to talk to the LCD. My project will be analog data logging with oversampling (averaging a lot of readings) - the 10 bits may work well enough, otherwise I'll have to use an offboard A/D.
Without having to use another IIC device, I am thinking it would be simpler to use the 4-pin interface bits + the control bits to the display, to save I/O. In other words, put the learning curve for IIC out awhile.
What does using IIC do to available memory (RAM and EEPROM) in the UNO? I am hoping that he UNO will be enough for awhile without "upgrading".
From what I could find, the Aduinos all have 10 bit A/D's. Is this correct? Oh, I would love to have at least 2 more bits.
Does this make sense?
