The characters output from the Seeeduino XIAO serial port can be read using the Arduino IDE serial monitor.
However, it cannot be read on a PC.
The blue LED flashes when reading on the Arduino IDE serial monitor. However, when I connect using VB.net or a standard serial monitor program, the blue LED stops blinking and becomes unreadable.
I use USB type-C as a serial port.
Has anyone created a program that can be read by a PC?
My experience: Putty works correctly. I have some self-programmed C# applications that do not accept / see output from the USB port.
Thank you for your advice.
This problem is resolved.
I use VisualBasic.
In VisualBasic, the default of “Handshake” in SerialPort property is “None”.
With “None”, no data will be sent even if connected to the Serial Port.
When I change from “None” to “RequestToSend”, data will be sent.
With Arduino M0-mini, data was sent as “None” even in the same program.
I haven’t tried it in other languages or environments, but be careful with VisualBasic.
I was able to connect using “Tera term”.
Best regards.
It is an addition.
You must also change the serialport property “DrtEnable” to “True”.
To mxe02560: Many thanks - with “DtrEnable = true” my C# program works fine.
