How to change serial timeout to a double number

Hello guys,

I have a simple question. I am reading strings from a board with fscanf.

serial_read_timeout = 1; my_nucleo_board.Timeout = serial_read_timeout;

the problem is matlab converts the variable serial_read_timeout to an integer on its own. How can i change it because i want to set the timeout to few miliseconds.

thnak you so much for your help !

there are no units in your example code

serial_read_timeout = 1;
my_nucleo_board.Timeout = serial_read_timeout;

note that this is exactly the same as

my_nucleo_board.Timeout = 1;

anyway, if that 1 is in milliseconds, and the function assumes seconds why not do

my_nucleo_board.Timeout = 0.001;

Huseyin Berkay Berabi's "Answer" moved here:

I tried it but matlab converts this 0.001 automatically to an integer ans basically 1 in this case.

i mean not always but when i pass 0.001 as an argument to set function, it still waits 1 second i assume matlabs converts it to an integer.

for example when i write 2.3 it waits 3 seconds for the time out

At first glance: either you need to change the settings of your board such that it works with milliseconds or you need to change the function that transmits the data to the board.
