UART through MSP-TS430RGC64USB Target Board

Other Parts Discussed in Thread: MSP430G2553, MSP430F5528, MAX3232

Hi,

I'm using the MSP-TS430RGC64USB target board to implement the MSP430F5528. I've used the Launchpad previously to implement UART on a MSP430G2553 that would spit out the data on a COM port. When I look at the MSP-TS430RGC64USB schematic, the TX and RX lines don't appear to be tied to the outside world. I've been using CCS v5.1.1

My question is: How do I implement UART, using the MSP-TS430RGC64USB board and MSP-FET430UIF debug interface, in order to send data and be able to read it through a terminal session (like Putty)?

Thanks

    On LaunchPad, teh UART output of the MSP is converted by an USB/SER converter TUSB on the LaunchPad and arrives on a virtual COM port at the PC. Thsi convenience circuitry is intended for debugging output and testing purposes only.
    On the 5528 target board, there is no such thing. Just the JTAG connector for a FET (which does NOT provide this backchannel-UART funcitonality of the LaunchPad FET) and the USB connector.

    If you want to use the UART for console communication, you'll have to attach a level shifter like the MAX3232 to the MSPs RX/TX lines and connect it to a serial port (or an USB/serial converter) on the PC. Or you program the USB part to identify as a virtual serial port to the PC. And directly send your data using the integrated USB controller.

    I was able to use the USB Developer's package examples to cobble together a USB-CDC project that outputted to a comm port. Thank you for your response and suggestion.
