Upload a bootloader to it!

Yes - just search for it, its been covered over 134 times

Search for software serial
469  Using Arduino / General Electronics / Re: Optimal communication between Arduino and Raspberry Pi on: February 11, 2014, 02:17:40 pm
@pwillard - I've been building systems for years & ALWAYS use a protocol based on checksum, never count on the data being sent, even over a short distance to remain intact. I've built systems that have had inter chip communication that just send basic data, and they have failed to pass the correct bit stream. To do things the correct way is NOT a 'because you can' thing, it's a 'if you are going to do it, do it right' thing.

I've never had a house fire, or been mugged or had any crime committed against ME, so The Fire department and Police forces should be disbanded based on your premise.

My question is, what would be the best protocol to send data from Arduino to Raspberry and vice versa.
Distance between them would be only a few centimeters so this shouldn't be a problem.

We were answering the question posed by luxy.

you need to post your code & how you have hooked things up, we cant guess!

There is, search for ADAFRUIT 7 segment library, you will have to re-define the numbers (led segments) but it's not to difficult.

I can't see if this has been asked - Is your Terminal/Serial Monitor set to the correct speed, stop bits etc. ?
473  Using Arduino / Microcontrollers / Re: arduino uno as isp on: February 11, 2014, 10:27:51 am
I see now, its the UNO doing the programming, it is to disable the reset of the programmer (UNO) when the bootload process starts. Normally when a Serial connection is started, the UNO would reset (part of the Bootloader starting procedure).
Hope this helps.

What have you found so far on this site and Google? I don't want to go over stuff you already have access to.
477  Using Arduino / General Electronics / Re: Optimal communication between Arduino and Raspberry Pi on: February 11, 2014, 05:28:44 am
You make up the protocol depending on how you want the data presented - for example I know in my data I will NEVER send 0xFF (255) so I use that as my start of valid data pointer - I also XOR all the bytes sent and check this value is the same at the end of the packet, if not I request a resend.

This has been on 2 arduinos, but the principle is the same on any coms.

Or wire in a PULL-DOWN resistor.
479  Using Arduino / Microcontrollers / Re: arduino uno as isp on: February 11, 2014, 03:43:12 am
The UNO may not need the Capacitor - But if it does, look at the writing on the board - RESET and GND are marked.

Use google my friend or search this forum, It can be done with a programmer or a second arduino
