I am using a TI F28379D launchpad. I am a beginner. I have successfully installed the embedded support for C2000 in my laptop. While trying to execute the c2807x_2837xx_adcpwmasynctest_ert.slx example code on my pc I am facing a problem. The code is successfully build and downloaded into the target device. I can see a 390 HZ rectangular wave in my oscilloscope. But the problem is the pulse width of the wave is not changing with the adc input supplied to the ADCINA0 Pin30.
I am using a 5V RPS to supply varying input voltage to PIN30. The value of the gain in the simulink model is 10
I observe that when the voltage from the RPS increases more than 3.5 V the led lights on the board become brighter. This makes me feel that I have something to do with the board.
I am unable to plot the data from the board in the simulink.
Please help me to solve this problem.

Hi,
The maximum voltage that you can use as input should be limited to 3.3V. If the voltage is greater than 3.3V it may damage the pins and the aboard. Refer to the processor data sheet for more information.
Thanks,
Aditya
