Simple GUI needed for embedded device

Development of a menu/GUI system for a linux based embedded device. The GUI will respond to commands coming from 4 buttons and 2 rotary dials. The GUI can be written in C or C++ and must use the SDL ([login to view URL]) library. ## Deliverables This GUI is for a small aircraft EFIS (Electronic Flight Information System). The GUI will consist of a menu system. The only input is commands from 6 buttons and 2 rotary dials. For testing the keybaord can be used to simulate the commands as follows: Key Description 1 button 1 2 button 2 3 button 3 4 button 4 5 button 5 6 button 6 A rotary dial 1 up B rotary dial 1 down C rotary dial 2 up D rotary dial 2 down The GUI will consist of simple lists of actions and must allow entry of numbers and letters must be allowed using an onscreen keypad controlled by the dials/buttons. Some items will be selected from lists. The GUI is divided into 4 pages or windows: **Common Tasks Engine Monitor Setup General Setup Flight Instrument Setup** Here is what each contains: **Common Tasks:** Altimeter/Baro Setting Compass GPS GVOR Routes This section is for commonly used settings that are accessed when airborne or just before flight such as the barometric pressure setting. **Engine Monitor Setup** RPM EGT CHT Fuel Pressure Fuel Flow Fuel Tank Manifold Pressure Oil Temp Oil Pressure Coolant Temp Voltage/AMPS Temp Sensors (OAT/IAT) Allows the ranges/settings for the various sensors to be viewed and modified. **General Setup** Flight Detect Global System Settings Maintenance Timers Alarms Data Logging Slave Setup Serial Ports Reset to Factory defaults Zero ASI/ VSI / AOA / Attitude Load/Save Flash Memory Load Firmware Update System Information General system settings. **Flight Instrument Setup** Altimeter Compass GPS GVOR Airspeed Global Settings All settings dealing with the flight instruments and GPS. I'll document what each does as time permits but you can guess from the description of most. The EFIS system has two rotary dials and 4 buttons. Here is a summary of how the dials/buttons will function: A press of the left rotary dial will bring up the **Common Functions Menu**. Rotating the dial will move through all 4 menus Common, Engine, General, Flight. Pushing the dial again will select that menu. Rotating the dial again will move up and down on that menu. Pressing the dial again will select that item and open a new page to change the settings for that item. The buttons will vary in their use and an on-screen description will appear above each button when there is a function that it will perform. Later versions will allow the buttons to be user set to perform tasks from the main display. * * *This broadcast message was sent to all bidders on Monday Aug 9, 2010 3:29:07 PM: Thanks for the interest in this project everyone.
