2.8" TFT Breakout w/ Arduino Fio/Leonardo?

Post by helium »

Hi,

I am working on a project in which I intend to use the Adafruit 2.8" TFT Touch Breakout ( http://www.adafruit.com/products/335 ).
I am planning on using it with the Arduino Fio v3 ( https://www.sparkfun.com/products/11520 ). The Arduino Fio v3 is essentially an Arduino Leonardo in a much smaller form factor, with many more pins broken out. It uses an ATmega32u4 with a 8mHz bootloader.

My question is, is the current library for the TFT screen able to work with an ATmega32u4 based Arduino, such as the Fio v3? If so, I'm imagining I would need to change the library code some to define new pins or something. Also, what pins would be the best to use? I am also going to be using SPI, I2C, and a few analog inputs on the Fio.
I was thinking that maybe the bootloader might also pose a problem because it is made for 8 mHz.

Basically, TFT breakout + Arduino Fio/Leonardo... possible...?
And pin arrangements?

Suggestions?

Also: I also plan on using a Micro SD card, as well as all the touchscreen capabilities of the screen. So SPI would go along with that. I know that the current TFT screen library is made to accomodate an SD card since the shield version of the screen includes one, but what about the breakout version?

I am also tring to get this TFT screen to work with 8MHz atmega328P setup. It works when I connect it to the UNO, but not with the 8MHz setup...

Any ideas?

Thanks

Actually, my TFT is not the one mentioned above but this one https://www.adafruit.com/product/1770
However, the answere could still apply to both, I hope...

Thanks

Never mind, I did not connect the RST to reset :/ It's working now...
