OLED display & signal sampling rate

OLED display & signal sampling rate

‎10-10-2011 01:04 AM

Dear Ni technicians

 

I am new to LabVIEW Embedded module. I use LabVIEW 2009 and Luminary LM3S8962 evaluation board. Recently my project need to use this board for data acquisition and display the input the waveform on the OLED display. However I find that the sampling rate is as low as around 10Hz, hence I can only get the waveform below 2Hz without aliasing. While the datasheet claim that the sampling frequency is about 16MHz. Is it because the display rate "drag" the "sampling rate"? if so, how could I improve it?

 

Here I attach the code and the actual result in the ppt file.

 

Many thanks! 🙂

 

Best regards,

Haiwen
