This is what we seem to have so far:
1) Ability to write to the LCD screen. We have routines for writing text (ascii only), and a simple graphical framework (from the adafruit project) that supports lines, rectangles, circles, triangles, etc
2) Ability to control the back-light brightness
3) Ability to read all buttons and sticks. The switches are not yet supported but I'll get to that shortly
4) Ability to read/write/erase the SPI Flash
5) Ability to talk to the radio
6) Ability to read from the touchscreen
7) Ability to write to the USART
8 ) Ability to measure battery voltage
9) The TX can act like a USB thumb-drive
10) Support for an internal filesystem such that files written by the PC can be read by the firmware
11) The ability to draw BMP files (both opaque and transparent)
12) An initial GUI framework
13) Ability to generate sound through the speaker
We do not yet have code to support:
* Channels other than the sticks
* More?
We only support the DEVO8 at the moment. Additionally, the code can be compiled on a PC with FLTK to make it easier to do GUI development.
