The supported devices for the AVR Dragon does NOT show any SAM devices. The AVR -ICE does show it. So does this mean you cannot use the Dragon but you can use the ICE?

I have a Due and was wondering if the 6502 emulator would run on it. With 512K Flash and 96K Ram it should have plenty of room to run programs. Also I was thinking of offloading the sound and video and keyboard onto a "co-processor" via SPI. The Parallax Propeller chip does video and a  PS2 keyboard easily and someone has written code for SID emulation with is extremely good. If not SPI maybe by 8 bit buss instead since the Due has plenty of I/O and the Propeller should be able to read it in.

Here is the modified SEEED Studio files as requested. The inputs are the same as the modified UTFT files I posted. The TouchScreen libraries have not been fully tested.

I could not get the modified UTFT to work with the UNO32 I have although it looks like there is code for it. I did take the library that was posted on the SEEEDStudio wiki page for the V1 shield and modified it to work with the UNO32 and I'll post it if you are interested.

Here is the modified UTFT Library. The changes are:

UTFT.h added 2 defines st7781 and SEEEDV10 to identify the St7781 and shield

st7781 folder in the UTFT\tftdrivers which contain initlcd.h and setxy.h for the ST7781

UTFT\hardware\arm\HW_SAM3X8E.h has been modified so if you use
#define SEEEDSTUDIO_SHIELD_V1_0 you will remap the 8 bit data buss to P2-P9 so you can plug in the SEEEDStudio Shield right into the Due.

If anyone is interested I also have modified the SEEEDStudio driver found on their WIKI page to work with the DUE

Well since no one has replied I'll answer it myself. I have modified UTFT to work with the SeeedStudio V1.0 Shield available at Radio Shack.

I was wondering if this shield could be used with the Due. I do have the graphics working (slowly) on a Fez Domino and working well on the Chipkit UNO32 which are also 3.3V so there wouldn't be any voltage translation problems.

With the Chipkit I took the existing libraries for the ST7781R and changed the direct accessing of the ports to match the Uno32 ports. With the FEZ Domino I took a ILI9341 driver and changed the command calls to the commands of the ST7781R and also changed the direct accessing of the ports to match the shield.

Could I take the ST7781R libraries and modify the direct port access to match the appropriate pins on the Due with the shield?
Or could the UTFT library be modified to use the ST7781R?

I recently picked up the Seeed Studio TFT 2.8" Shield V1.0 from Radio Shack and was planning on using it with the Due for a GPS based project and was wondering if the TFT library on Seeed Studio's Wiki would be compatible with the Due? Thanks

Thanks for the suggestions. I haven't used C in a long time so I have forgot some of the functions such as strdup.
10  Using Arduino / Programming Questions / Array of File Names on: July 31, 2012, 08:57:01 pm
I am reading a SD card and I want to store an array that contains the file names that are on a file here is the code I'm using

Code:
File getDirectoryPage(File dir, int num) {
   File entry;
   char* fName[num];
   for(int i=0; i<num; i++) {
     entry = dir.openNextFile();
     fName[i] = entry.name();
     entry.close();
   }
   return dir;
}


When I use it to do 5 names all entries in the FName array points to the last name. Is there a better way to store entry.name() into an array of strings? Thanks.

Edit: Added code tags

I too live in Pennsylvania, 30 miles south of Erie, PA. I have a degree in Electrical Engineering and have many micro controllers such as the Arduino, Propeller, Basic Stamp, Pic Chips and MSP430. I am currently working on a Arduino Pro Mini interfaced serially with a Propeller.

I found a cheap 4.3" touchscreen ($18 US plus shipping) at http://www.rayslogic.com/Propeller/Products/PSB/PSB_Display.htm#Breakout_Boards. The info on the page is for the Parallax Propeller Microcontroller. He carries a breakout board to go with it that permits the use of 6 bit color. There is also a reference to a 24 bit color breakout board. Both have I2C interface for the touchscreen part. It may be able to interface with the Arduino.

I would be interested on how this turns out. I have a breadboard compatable board using the ENC28J60 called the PropNIC found at http://ucontroller.com/documentation/PropNICDoc.html. It's made for another controller, Parallax's Propeller, but should work with the Arduino.

Has there been any activity with the Pittsburgh area? I like kernsy live an hour north of Pittsburgh and would like to be involved in an Arduino/Micro-Controller club.
