Error of too many output arguments

Hi, I have a piece of code:

ChunkSize=5000*16;

IF=length(F);

D=[];

for send_count=0:ChunkSize:IF-1

bytecount=min(send_count+ ChunkSize, IF)-send_count;

D=F(send_count+1:send_count+bytecount);

sentcount=fprintf(s,D);

However I have the error of:

??? Error using ==> serial.fprintf

Too many output arguments.

Error in ==> serial_interface>button_send_Callback at 160

sentcount=fprintf(s,D);

I think the main concern is my MATLAB is not compatible with the newer version.Hence how could I solved this?

Serial printf doesn't support the output argument. I will have a fix for you a bit later today.

Replace

sentcount=fprintf(s,D);

with

oldvalcount = s.ValuesSent;

fprintf(s,D);

sentcount = s.ValuesSent - oldvalcount;
