Hi there, I tried to use ‘flush’ to clear the serial buffer sent from MATLAB to Arduino, but I can’t make it. Here is a simple code in MATLAB:
device = serialport("/dev/cu.usbmodem2101",9600);
write(device, 1:5, "uint8");
The device.NumBytesAvailable = 0, and device.NumBytesWritten = 5, and after I run this:
flush(device);
the device.NumBytesWritten is still 5.
I’ve tried different MATLAB versions (2022b,and 2019b, and tried to clear this in arduino, but neither works.
Please help me. I don’t know what’s going wrong and I’ve been stuck in this for several days. Thanks.Hi there, I tried to use ‘flush’ to clear the serial buffer sent from MATLAB to Arduino, but I can’t make it. Here is a simple code in MATLAB:
