I have an application that is not too dissimilar. Update by SD card would be fantastic, especially since I have the opportunity to download upgrades via wifi. At the moment I am hoping to configure a V-USB bootloader for Calunium. Then upgrades would be possible with just a plain USB connection without needing FTDI on-board or an FTDI adaptor. Is that a possibility for you?

Probably not, this device has no network access. But thanks for the suggestion!

Has anyone managed to get the GLCD library to work with the 1284P and Arduino 1.0 ???

I have made a couple of changes to the GLCD library files to make it compile but I'm getting nothing on the screen.

I'm posting here as lots of 1284P users have posted in the thread and I was hoping that one had.

I have started a thread in the LCD section here : http://arduino.cc/forum/index.php/topic,91961.msg690733.html#msg690733

Hi, I'm trying to burn this bootloader onto my atmega on a board through the ISP header.
I am using the Arduino as the ISP programmer.

When I use the latest version of the sketch, I get the error:

Code:

avrdude: stk500_getsync(): not in sync: resp=0x00

which is pretty generic, and I have no clue what to do with it.

When I use the older version of the ArduinoISP sketch (the version that ships with the 1.0 IDE) I get

Code:

avrdude: stk500_paged_write(): (a) protocol error, expect=0x14, resp=0x64
avrdude: stk500_cmd(): programmer is out of sync

which I still don't have a clue.

Does anyone have a solution for this?
The same errors come up both through the IDE and with the command line avrdude.
And to clarify, It is a Reprap Gen 7 board (I dont think this should matter) and I am running it at 20mhz.

Thanks!

I ended up having to buy an AVR ISP MK2 and then you have to connect using AVR Studio 5 and begin communications at the absolute slowest speed the program allows.  Once communicating you can set the flags etc and push the speed back up again, I normally use 1MHz just to upload the boot loader.

Don't you have a much different looking version of that posted elsewhere?

This one

Same thing

Siked!... Much thanks to *CrossRoads
"rushing posts"

Yes, a little bit different since you've last seen it. I have changed a couple of things that could have been potential issues...
I've also swapped out the tantalum for a ceramic.

Thanks again man, you helped me a bunch.
I probably still would've been messing around the 1284p and MKii lol

How'd you get from eagle to google sketchup?

It was a little annoying to get going on my mac.

Google sketchup will not place the components in automatically but in sketchup you can go to: File: 3D Warehouse: Get Models, then from there type in a component and chances are you will find it. Super cool

For the 1284p I just grabbed one called "TQFP44" by shg.
You may have to scale the board down before adding in components.
The 44 pin SMD was very small when I uploaded it, so I had to scale down the board 1000 time.
Plugins: Scale: Scale down 1000.

Ack, well, maybe some day in the future when I have more time then.
