Original question:

TM4C123GH6PM: FTDI device slave driver

MSP432E401Y: USB serial device compatibility

Part Number: MSP432E401Y

Is there any reference which USB serial adapters are natively supported by the TI-RTOS USB library? Like FTDI, CP210x,...

Thank you and regards 

Peter

    Hi,

     As mentioned by Ralph in the post you reference, there are no specific drivers in the SDK for FTDI support but that does not prevent users from developing their own USB drivers for FTDI protocol. The examples at C:\ti\simplelink_msp432e4_sdk_4_20_00_12\examples\nortos\MSP_EXP432E401Y\usblib\usbdevcdcserial and C:\ti\simplelink_msp432e4_sdk_4_20_00_12\examples\nortos\MSP_EXP432E401Y\usblib\usbdevcserial would be a good starting place as they show how to create a device as a USB to UART bridge.

    Hi Charles,

    I understand but as I imagine that someone has already done that and that you yourself may have tested USB serial devices already, it would be helpful to work based on that experience instead of developing drivers just for the pleasure to do so.

    Regards

    Hi Peter,

      Perhaps I'm still unclear as to what FTDI driver you are looking for. For TI-RTOS, there are USB CDC examples for serial host and device at:

    C:\ti\simplelink_msp432e4_sdk_4_20_00_12\examples\rtos\MSP_EXP432E401Y\usblib\usb_serial_device

    C:\ti\simplelink_msp432e4_sdk_4_20_00_12\examples\rtos\MSP_EXP432E401Y\usblib\usb_cdc_serial_host

    There are all the examples we have for USB enumeration as a CDC class serial device.
