Thank You.

Can either of you post the code so others can use it?

CrossRoads,

On the schematic it says that one processor supplies the clock to the other processor. I see the single crystal but I don't see the connection between the processors for supplying the clock. That would be a good feature to add.

CrossRoads,

Keeping pin compatibly across the different processors isn't too high on my priority.

I just keep track of the pin differences and update the code when necessary.

Here is the pins_arduino.c that I have been using that works with many processors.

What device are you using to upload the sketches on the FTDI port?

I am using the BUB board from Moderndevice and it already has the capacitor on the reset line so I removed the capacitor, C3 shown on your schematic and uploads smoothed out for me.

I am also uploading at 115200 too with no issues.

I created a quick blog site and posted the pins_arduino.c file

http://mnmis.wordpress.com/

The rest is at the beginning of this forum post.

When I get time, I'll find a site that I can upload files to.

Hello,

I just want to add to this post about creating a bootloader for the 1284p.

I took the information from this post and edited the boards.txt file for 16Mhz operation.
I then downloaded the file stk500v2_new.zip from the aka47 website and compiled a hex file for 16Mhz operation
on my PC running Linux Fedora 15.

I then used the Arduino IDE to upload the bootloader using a usbtiny programmer, I had a verification error but it seemed to work.
I also had to update avrdude and ardude.conf in the arduino-0022 path to the latest version.

I then downloaded the core files from the Sanguino site and edited the wiring_pins.c file to add the pins for the 644p/1284p chips.

Here is a list of what I tested so far.
All digital outputs.
All PWM outputs.
Serial1 works also.

I haven't tested the Analog inputs or the tone functions as of yet.

I did have a lot of problems loading the bootloader at first. I had to put some bypass caps on the breadboard to get this to work.

Thanks to everyone for the information that everyone posted previously to help me get this going.

Question, Does anyone have any information on programming this board that you are designing?

Thanks for the update. I found that it didn't work and I didn't have the time to debug it.
I'll post if I find any more problems.

Thanks. Compiles now. Now I need to test the new functions.

I tried to use your code but HT1632_ADDR_BITS is undefined.

What is it set to?

liudr,

What would Doom II get me?

I looked at the library code real quick this morning and there is a 50 ms startup delay.

It also looks like there is a 4.5ms delay writing to the LCD so that is probably why it works.

My C programming is really rusty but that is what it looks looks to me.

jrraines,

I finally made it to Axman and purchased one of the LCD's.

I am using it with a JeeNode and it worked with no modifications to the code. Maybe you got a bad one, or I got lucky.
