Hi, I am using a virtual USP port with with FTDI USB driver for my atmega 328 microprocessor and I get some 8-bit data from the processor. But, the 3 most significant bits are always 1, so I can use only the 5 least significant bits. This is the code that gets the data:
[data,count,msg] = fread(s, 255, 'uint8')
I changed baud rate and I set the data to be sent as 8 bits and I tried everything else but there seems to be but no way to get real 8-bit data. Can anyone help?? Thanks in advance, Kai

If you are using an Arduino board you might want to look at the following: http://www.mathworks.com/academia/arduino-software/
