parse hex data from serial port and plot real time graph

Hello,

 

Am trying to save the data to an appended array as attached, but it only fill the first block, and keep on overwriting as new data is passed to the appended array. Any ideas of how I can make this feasible? A sample block diagram and front panel is attached.

 

Also I intend to do some signal processing, such as how to find the frequency of the sine wave, as well as the phase received after the typecast conversion. So far, I tried using Spectural measurments, but I get nothing on the power spectrum graphical indicator for instance.

 

Appreciate any ideas, suggestion on how I can make this possible. 

 

Gavin.

You need to use a shift register to hold the array of appended data.  And your build array will build your new data onto that.

Thanks for the suggestion, shift registers works just fine.
