I was trying to transmit some data(numbers) from my Renesas QSK 62P Plus micro controller to MATLAB through the serial port.
However, if I used the command 'fscanf(s)', it terminates the communication then and there (without the default 10 seconds getting over), displaying that it received nothing in the output variable.
But, if I use 'fread(s)', it gives me the correct ASCII codes of the numbers my micro controller generated. I tried to use both the 'fscanf(s)' and 'fread(s)' together, assigning them different output variables. That makes the communication run for the stipulated 10 seconds. But the data is divided between the 'fscanf(s)' output variable and the 'fread(s)' output variable.
Eg. if my microcontroller transmitted '12345', my output variable for 'fread(s)' contained 9 values in ASCII code, which includes '0' & '10' in the beginning and '10' and '13' at the end. However, on combining the 'fscanf(s)' and 'fread(s)' commands in a single execution, the 'fscanf(s)' takes the first two values, i.e. '0' & '10', and 'fread(s)' takes the rest of the ASCII values.
I am just guessing this scenario as when both the variables are executed together, the 'fscanf(s)' variable shows a 0X0 array, while 'fread(s)' shows all the values (7, in this case) except the first two values of '0' and '13', which it shows if 'fread(s)' command is exclusively executed.
My question is how do I make the 'fscanf(s)' command spit out the numbers? I tried to output characters just in case it had problem with numbers but encountered the same error. I know my communication works well as the data is well received, as shown in the ASCII output.
