Got the 1284p working requires updating the included avrdude on 18 though haven't tried 19 yet see here:

Uses the sanguino core

[Reply #16 on:]

Using the modified code mdmetzle provided should do the trick?

[Reply #17 on:]

Mark S. Do you have links to these?

Very nice work on all of them.

Anyone know about the 1284P?

The 1284P is used in the Pololu controller

http://www.pololu.com/catalog/category/86

I have it fully working with Arduino including bootloader. There usb driver is NOT compatible with the Mac, but I was able to connect directly to the RX0/TX0 pins with an ftdi cable and it worked fine.

I have an updated list of cpus working with the core files

I will get it documented and post the code soon

Wow, that's quite a list Mark. You have made a great contribution to the Arduino world, thanks.

Are these just on 16Mhz?

Have you done any testing on the ATmega644 at 20Mhz for example?
As I uncderstand it, it is normally only minor changes to get that to work too.

Mowcius

[Reply #22 on:]

Are these just on 16Mhz?

I suspect the fourth column in the table is the processor speed.

[Reply #23 on:]

In regards to the speeds, are these mods done in the individual bootloader for that chip etc, or are they done in some base files for the Arduino IDE?
The reason I ask is, if I have a project which uses say 5 processors, and I want to use the main one at 20Mhz but the other 4 at 16Mhz, am I going to have to modify the arduino IDE files in some way each time I want to program the 20Mhz and change it back to program the 16Mhz ones?

Great work on the above guys

Thanks

[Reply #24 on:]

Ahh yes I see.

Some processors need to be sorted for 20Mhz too then.

There needs to be some modifications for different speeds. You have to program them using a different core file if they are different speeds or else the basic fuctions (delays etc) will not work corrently at the new speed.

Mowcius

[Reply #26 on:]

The only changes that need to be made is the F_CPU speed setting. This is done in the MAKEFILE for the bootloader and in boards.txt for each cpu.  The core file take care of the cpu speeds from that. No changes required.

I did have a problem with the the F_CPU=14.7456, some of the macros needed to be changed else it drifted 20 minutes in 8 hours.

I have a new web page with all of this stuff. I should have my core files up there later tongiht

WanaGo, the ONLY thing you would have to do is to create a new entry in the "boards.txt" file that has the CPU SPEED changed to 20 mhz, the core files take care of the rest. You would just have to select which ever "board" you are currently using.

If anyone knows of other boards or CPUs that are available, let me know and I will add them to my test suite.

Looks great.

That 3920 with LCD driver looks cool.

Mark;

 Does the location instructions from the following playground information for 3rd party processors apply?

Third-Party Hardware
Support for third-party hardware can be added to the hardware directory of your sketchbook directory. Platforms installed there may include board definitions (which appear in the board menu), core libraries, bootloaders, and programmer definitions. To install, create the hardware directory, then unzip the third-party platform into its own sub-directory. (Don't use "arduino" as the sub-directory name or you'll override the built-in Arduino platform.) To uninstall, simply delete its directory. [glow]We would use a arduino folder name for your files here, correct?[/glow]


For details on creating packages for third-party hardware, see the platforms page on the Google Code developers site.

Brilliant thanks, thats what I needed to know
