Output pixel larger than the desired pixel

[fatimamaz]

Please answer the following question if it is clear.
I am using Altera FPGA board for saving a snapshot to a frame buffer and to send it serially to Matlab. My problem is that all the parts of my code are right but the received data to Matlab code are 14 bits rather than 8 bits.

I tested each memory alone by defining a specific pixel at its input and output and checking the final output on Matlab, however all the parts seem to be correct.

Would you help me to diagnose the problem?

How is the data captured by matlab?

Can you please share the MATLAB code used for receiving the data as well as FPGA code used for sending the data ?

Here is my Matlab code.

clear all;
delete(instrfindall);  
s = serial('COM6');  
info=get(s,{'Type','Name','Port'});
set(s,'BaudRate',115200);  
s.InputBufferSize = 8000;
s.Timeout =200;


fopen(s)
fprintf(s,'%c','a') 
Buffer = fscanf(s,'%c');
fclose(s)
binary_data=dec2bin(Buffer,8);
