I, its possible to install pyxis in one arduino, with screen and pushbuttons as keyboard?
cause i read that all videos of Pyxis on internet have 2 boards, touchscreen and keyboard.
i extract this from a website
"The demo project use two microcontrollers. One for manage the user interface part
(use arduino mega) and another one use mega2560 + dataflash for handle the whole display
(it's on the touch screen shiled board)"
Yes you can install Pyxis on just the one Arduino. The LCD & ButtonPad controls are separate from the OS and it can work without them. However the main reason for Pyxis was so you could run compiled apps without having to reflash the chip...if you don't at least use the SD card that kind of defeats the purpose, though there is a "lite" version that will allow you to run apps from EEPROM instead of uSD.
