I'm using the TI Board F28379D with Simulink to make an acquisition of sinusoidal signal of 100Hz as frequency. Firstly, I try just to create just a signal with a sine wave block and send the signal to an scope to visualize using the external mode. I used a acquisition frequency of 10 kHz that should be sufficient, but when I'm using the external mode I haven't this acquisition frequency . I tried to use the serial communication without the external mode, but the result is similar.
Here the signal obtained using the external mode.
Anyone have a suggestion how to visualize this kind of signal?
Any help will be very appreciated.
