USING REAL TIME WINDOWS TARGET TO COMPILE AND EXECUTE A SIMULINK PROGRAM When you log onto the PC assigned to your group, open up Matlab 6.1 Next type in simulink in the Matlab command window, this opens up the Simulink library which contains all the blocks for constructing a simulink program. The test program stgsample1.mdl should already be present under the c:\Matlab6p1\work directory , if not it can be downloaded from the ECE496 website (In the ECE 496 Administration Web Simulink Model Example For Windows) Copy the test program onto your PC using a floppy disk as there is no network connection for any PCs. Now through Simulink the stgsample1.mdl can be opened and used as a test program to check your hardware OR also as a means to build your control program on it. A picture of the sample program is shown in Figure 1. Typing in stglib at the MATLAB command prompt will bring up the software library for the ServoToGo Board. The different hardware blocks (ADC, DAC etc) in the sample program have been taken from stglib The options for using the ADC, DAC, Read Encoder and Digital Output blocks have been shown in figures 2 through 5. They can be accessed by double clicking on each block. Figure 1 Figure 2 Figure 3 Figure 4 Figure 5 The settings for all of the respective blocks should be set as shown in the above figures. You can specify the channel you want to use in the blocks above but the change should be reflected in the hardware too (i.e the connector to the break out board of the Servo To Go or any other board should also be switched to the respective channel). After all the settings are set in the control program, the Real Time Workshop and RTWT settings must be set also. The procedure to do this is given b
