MSP-EXP430F5529LP: Code necessity

Taku Murayama
Intellectual 970 points
Part Number: MSP-EXP430F5529LP

Tool/software:

I found the application note as below. With regard to conversion using a microcomputer, is it correct to recognize that writing code is necessary in order to use it as a Bridge IC? Also, is a special driver required for the USB side?

Application Brief： USB-to-UART Bridge Made Simple With MSP430 MCUs

    This AB is related to LP target device (5529), and to use it as USB-to-UART bridge is provided TI source code. On Win 10, OS X or Linux, 5529 (CDC device) should be enumerated automatically by OS without any drivers.

    Communication is done like this: 5529 USB <-> 5529 UART <-> FET(5528) UART <-> FET(5528) USB

    With uploaded example after board enumeration there should be two UART(CDC) ports used for terminal characters exchange.

    AB source code is not related to FET(5528) USB-to-UART bridge that should work anyway. FET(5528) USB-to-UART bridge is covered by FET firmware. And drivers for LP must be installed.

    Hi Taku,

    As the application brief mentions, the is an example code that can perform the basic functionality already. So in that instance you would not need to write additional code. If you want to change something about the implementation you would need to write more code.
