Pybricks and OpenMV H7 Plus UART compatibility

[OPSLeoGong]

I am currently in the WRO robosports Internationals (We are from Australia). ive been having trouble connect the pybricks UART via from pybricks.iodevices import UARTdevice to the OpenMV. Im having trouble connecting the two because the pybricks side says that you cant import UARTDevice and can someone please help me?

the top one is for openmv ide and bottom is for pybricks

This feature hasn't made it into an official release yet AFAIK. You can use a nightly build of the firmware if you need the UARTDevice class. Be aware though that lots of things have changed in the firmware and may not everything may work correctly.

And check that the D in device is upper case. You wrote UARTdevice in once above.

There is some old documentation from Pybricks 2.x at https://pybricks.com/ev3-micropython/iodevices.html#uart-device.

But not all methods are implemented yet. Only read() and write() are working AFAIK.

if i were to send data from openmv cam, i have to use bytes and convert the bytes on the hub using ustruct is that correct?

[OPSLeoGong]

And if so how would i decode the data usiong ustruct

[dlech]

If the OpenMV camera uses binary data, then yes, ustruct would probably be the easiest way to create the data bytes object. You would need to find some documentation that explains the protocol used on the device. Every device is going to be different.

thanks

But openmv can use both a direct message or binary but the pybricks hub only supports binary in UARTDevice. Thats why im using ustruct now

im kind of new so im not very familiar
