Hi, I'm trying to plot some real-time data recieved from an Arduino Uno R3 in matlab R2020b but I'm not sure what baudrate should I set for data transfer. In my case the higher the baudrate is better but if I cant graph it properly it would be of no value. I want to know if I set the baudrate to max (which is 2000000) and since every sample I recieve from arduino would be 10 bits long (it's a number between 0 to 1.1) will I be able to plot them in real time efficiently? is Matlab able to do that?

I think you are asking about a direct connection to MATLAB from an Uno, but most of the workflows here on the ThingSpeak community are about wirelessly connected IoT devices. signal_processing plotting real-time serial sesrial_data

Hi, I'm trying to send with a serial connection a signal. The signal is just a byte (uint8) that I want to send to my evaluation board every 1 millisecond using Simulink. How can I do that? I tried using the Serial Send block, but the result is different from what I expected to see. Then I tried to use the To instrument block, but I don't know why there isn't the port COM 5 so I couldn't use it.
