Hi all,
Thank you in advance for your help.
I've got a vector of uint8 numerica values ( from 0 to 255) that I would like to save in a .txt file.
I would need to have a .txt file in which each row is a single character. After having stored this .txt file in a SD card I would need to read it in Arduino whose file.read() function works reading one byte at a time.
I was thinking then that I would need to create a .txt file in which each row is the ASCII value correspondent to my uint8 number. Is there an easy way to do that using the fprint() function?
Do you have suggestions?
Thank you for your help!!

You may save it using the '%d' formatting operator and save it line by line to a text file. Use '\n' for moving to the next line.
Please see this doc and the examples in it to understand how to print your ascii values line by line.
https://in.mathworks.com/help/matlab/ref/fprintf.html
In general, I have found the examples very useful in learning a new function or tool in matlab. Try picking out the first example in the doc.
Hope it Helps!
