		+	==How do I install the USB Debug Ports driver on Windows 8?==
		+	Windows 8 implements a Driver Signature Enforcer that does not allow you easily install unsigned drivers. Please follow the procedure below to install the drivers for the Eagle 50 USB debug port.
		+
		+	*1. Download and unzip the [http://www.micromint.com/updates/eagle/eagle50-USB-debug-drivers.zip Eagle 50/50E USB Debugger Drivers]
		+	*2. Move your mouse to the top right hand corner of your screen to bring out the sidebar
		+	*3. Click on the “Settings” icon
		+	*4. Click on “Change PC Settings” in the lower right hand corner of the “Settings” bar
		+	*5. Click on “General” in the PC Settings App
		+	*6. Scroll down on the right hand side of the screen and select “Restart now” under the “Advanced startup” section
		+	*7. After the computer restarts click on “Advanced options”
		+	*8. Click on “Startup settings”
		+	*9. Click on “Restart”
		+	*10. When prompted press the number 7 to select “Disable driver signature enforcement”
		+	*11. Plug in the Eagle 50 to the computers USB port
		+	*12. Open Windows 8’s “Device Manager”
		+	*13. Double click on “Stellaris Evaluation Board” under “Other Devices” in “Device Manager”
		+	*14. Click “Update Driver”
		+	*15. Click “Browse My Computer for Driver”
		+	*16. Click the “Browse” button and find where the driver was unzipped on your computer
		+	*17. Click “Next”
		+	*18. When Windows 8 warns you that the driver is not signed click “Install driver software anyway”
		+	*19. In “Device Manager” double click the second instance of “Stellaris Evaluation Board” under “Other Devices”
		+	*20. Perform steps 14 through 18 for the second instance

	==What is the difference between standalone and application mode?==		==What is the difference between standalone and application mode?==
	Application mode assumes a bootloader is used at 0x0000 so the application is relocated to 0x2000. Standalone mode assumes no bootloader is used so the application is relocated to 0x0000. To use standalone mode (no bootloader), link with standalone.ld (gcc) or standalone.icf (IAR) and load the binary at 0x0000. To use application mode, link with application.ld (gcc) or application.icf (IAR) and load the binary at 0x2000. The bootloader must be at 0x0000 if you use application mode.

The DAC can be updated at a maximum of 150 kHz for 1 channel. The data transfer is 16-bits at 25 MHz which is a total of 640 nS per data transfer but the DAC has a settling time of 6 µS so the total time needed is 6.64 µS. All 4 channels of the DAC can be updated at a maximum of 116 kHz. This is accomplished by sending the data for all 4 channels and updating all of the outputs on the last data transfer.

	The bootloader allows firmware updates from the Ethernet port (Eagle 50E) or serial port (Eagle 50). If you will be doing firmware updates via the USB device port or a JTAG, a bootloader is not required. If you will be doing debugging, it is easier to debug applications in standalone mode without a bootloader. Debugging with a bootloader present requires loading it before the application, which makes the setup more complex. Most applications do not use a bootloader but the default Eagle setup uses one so customers without a USB debug port or a JTAG have a way of updating their firmware.

-	~~==Can I develop and debug code for the Eagle using a Linux PC? a Mac OS X workstation?==~~
-	~~Yes. CodeBlocks, Eclipse, OpenOCD and GNU cross compilers for ARM are available for Windows, Linux and Mac OS X. EWARM is only available for Microsoft Windows.~~
-
-	~~==What filesystem types, volume size and filename formats are supported on microSD cards?==~~
-	The code examples use the FatFS 0.04b library which supports FAT12, FAT16 and FAT32 filesystems. We have tested 4GB microSD cards but the library supports larger volumes. The filename format is 8.3. Long file names are implemented in FatFS 0.07 or above.
-
-	~~==How can I detect if the application is compiled with IAR or GCC?==~~
-	~~You can use compiler predefined macros as in the example below.~~
-
-	~~#if defined(__IAR_SYSTEMS_ICC__)~~
-	~~/* Code to use with IAR compiler */~~
-	~~#elif defined(__GNUC__)~~
-	~~/* Code to use with GCC compiler */~~
-	~~#else~~
-	~~#warning Compiler is not supported~~
-	~~#endif~~
-
-	~~For more details on predefined macros, consult the C preprocessor manuals.~~
-
-	~~[http://gcc.gnu.org/onlinedocs/gcc-4.4.4/cpp/ GNU C Preprocessor]~~
-
-	~~==Why are certain source code statements not executed when single stepping?==~~
-	When you enable code optimization, the object code does not necessarily follow the same sequence as the source code. Optimizing compilers like IAR or GCC use loop unrolling, loop collapsing, branch elimination and other techniques that rearrange code to increase execution speed and/or reduce code size. A common practice during development is to disable optimization when debugging. Compiler optimizations should normally be enabled after most of the debugging is done and the code is stable. For a more consistent debugging environment, the StellarisWare driver library should be compiled with the same options and compiler version as the application.
