Wrong Baudrate in INO?

[SvenHi]

In the arduino sktech, there is the baud rate config for 115200 in all GUI and Atmel Studio project 57600.

=> Is the Arduino sketch really up to date? Even if I change the baud rate, I get no matching values in the GUI

Hello SvenHi, The SerialUSB on Arduino Zero is a is an emulated serial port (USB-CDC). The SerialUSB class is a special Serial instance which use the hardware USB the speed will always be 115200.

Thank you for response!

 

Does this mean, I have to change the Baudrate in the Processing GUI (for USB)?

 

Original code healthypi_desktop.pde:     port = new Serial(this, selectedPort, 57600);

 

Or does this setting not matter?

 

In case this setting does not cause conflict with the 115200 baudrate of CDC, I have to search for other issues on my setup.

I have the problem, that the device does work in general with Atmel Studio firmware on Raspberry.

 

If I replace the flash with Arduino Zero bootloader, download INO via Arduino, and use the PC GUI (Win10,64Bit)

then I have in general communication between device and GUI, but no valid data in visualization...

 

Best regard
