 Making a part look pretty even after it is functionaly done can be a very good thing, espically when the part gets cut from the bot and you get to keep it as a trophey. Take pride in your work. - Andy A. [more] |

Re: How to Hook up LCD
The Backpack handles the serial communication and can be hooked up directly to the TTL port on the RC (gnd-to-gnd, 5v-to-5v, Backpack/Rx-to-RC/Tx). I do have example code that uses a digital output instead to communicate through, but the TTL port is the easiest way to do so and has the advantage of using more efficent dedicated hardware. Kevin's example is very clear too.
The OI does not have a serial port that you can control well enough to allow you to hook your LCD up directly to it. You'd need something to take input from the OI's Dashboard port, decipher the format, extract the data you wish to display, then issue the appropriate sequence of LCD commands.
