Hello. I have tried to launch 3 example projects in MCUXpresso IDE called composite_cdc_vcom_cdc_vcom. Description say that:
The demo echoes back any character it receives.
But i see only 2 COM ports appeared and no echo characters if i send data to them. I have looked more closely to project and see that vcomInstance->startTransactions always 0.
Tell me please are example project correct and have tested?
Solved! Go to Solution.
i have tested with another terminal app and see that it work
Hi
Try one of these to verify the HW (and the PC); they all contain composites with CDC:

See the following video for dual-port USB device/host simulation:

In case of difficulties with the standard examples you can fall back on the uTasker project as industrially proven USB-CDC solution.
