Portenta x8 serial communication with other devices using breakout board

[siqizheng]

Hi Everyone,

I have an arduino portenta x8 along with a breakout board. I have been trying to connect other devices to the x8 serially, and have been unsuccessful. Furthermore, I am primarily looking for UART, CAN or I2C protocol communication. If anyone could guide me in this direction or list any relevant libraries that I'd be able to use, I would highly appreciate that! Let me know if you all have any questions.

There's an example for using I2C:

Portenta X8: I2C - No such file or directory: '/dev/i2c-1

Hi all, according to the documentation and the following example it's possible to run I2C comm from the Linux side. [image] from periphery import I2C # Open i2c-1 controller i2c = I2C("/dev/i2c-1") # Read byte at address 0x100 of EEPROM at 0x50 msgs = [I2C.Message([0x01, 0x00]), I2C.Message([0x00], read=True)] i2c.transfer(0x50, msgs) print("0x100: 0x{:02x}".format(msgs[1].data[0])) i2c.close() But I"m getting the following error: Traceback (most recent call last): File "/usr/local/lib…

Thank you jordy,
I want to communicate using the serial approach. I met the similar problem as you. I wondered if I need to enable the serial support before using the device, but I don't know how to enable it.
