 +===== Standalone Firmware for the EZ-USB FX3 =====
 +On FX3 based FPGA Boards the Flash support is always enabled. Automatic FPGA configuration is enabled by default, but can be disabled by <code>#define DISABLE_FLASH_CONFIG</code>

-===== Default firmware / Standalone example ===== +
- +
-The SDK contains either a default firmware (which is also factory installed on [[http://www.ztex.de/usb-fpga-2/|Series 2 FPGA Boards]]) +
-or a  ''standalone'' examples for each ZTEX FPGA board that support Flash. These sources define an "empty" Firmware with standalone capabilities, e.g.: +
- +
-<code c> +
-#include[ztex-conf.h]     // Loads the configuration macros, see ztex-conf.h for the available macros +
-#include[ztex-utils.h]     // include basic functions and variables +
- +
-// selects the target FPGA Board +
-IDENTITY_UFM_1_11(10.12.0.0,0);  +
- +
-// this product string can also used for identification by the host software +
-#define[PRODUCT_STRING]["Standalone firmware"] +
- +
-// enable Flash support +
-ENABLE_FLASH; +
-ENABLE_FLASH_BITSTREAM; +
- +
-#include[ztex.h] +
- +
-void main(void)  +
-{ +
-    init_USB(); // init everything +
- +
-    while (1) { } //  twiddle thumbs +
