Signal graph with eGUI

Hi all,

 

I need to graph a sinusoidal signal using the graph object from eGUI. I'm using the TWR-LCD-RGB and the TWR-K70 module.

What I'm doing is using the ADC0 and acquiring the sinusoidal from a function generator. I acquire the data and then convert it to float after mapping the acquired data. According to what I've found I need to add data to the traces of the graph, the format of this data being D4D_GRAPH_VALUE, but apparently the D4D_GRAPH_VALUE data type retrieves integers and no float values.

 

What should I do to graph the sinusoidal signal?

 

Thanks in advance,

 

Elisa
