Microblaze Making a new empty project: Instead of choosing helloworld in file >> new >> application project choose empty application.
Figure 1
Right click on project name and choose new >> file / source file File is like helloworld.c in the figure1 and source figure1.it’s so important to enter a name with .c suffix like amir.c. It’s a better way to click on source file.

How to find a header file for my project? You should search your header D:\XILINX\14.7\ISE_DS\EDK\sw\XilinxProcessorIPLib\drivers

When you find it copy it and paste to src of your project in SDK. EX: xscutimer.h is in scutimer_v1_02_a so you scutimer_v1_02_a in src and then resolve all errors by deleting extra folders.

[email protected] EX: tmrctr_v2_05_a is used for taking time by xtmrctr.h . For using the Examples you can search D:\XILINX\14.7\ISE_DS\EDK\sw\XilinxProcessorIPLib\drivers(and with ie. DEV c++).
Taking exceuting time for a code : First of all choose the timer :
Figure 2
In XPS set the timer in mb_plb mode and set the UCF as follows.

Net fpga_0_RS232_RX_pin LOC=P14; Net fpga_0_RS232_TX_pin LOC=P12; Net fpga_0_clk_1_sys_clk_pin TNM_NET = sys_clk_pin; TIMESPEC TS_sys_clk_pin = PERIOD sys_clk_pin 48000 kHz; Net fpga_0_clk_1_sys_clk_pin LOC=P56; Net fpga_0_rst_1_sys_rst_pin TIG; Net fpga_0_rst_1_sys_rst_pin LOC=P17;
