Problems regarding UART module.

Other Parts Discussed in Thread: MSP430F5529, MAX3232

Hello, I used to work with uart of msp430-expF5529. I need to send ADC data on my PC(win7). I have gone through, available driverlib sample codes. But I am just unable to understand, implement UART module. Later, I have gone for BSL and USB developer packages; Still couldn't find a  way out, Now I am totally confused.

Here, I need just a guidance how to use UART module or similar modules in order to place serial data into my pc. I am demanding just directives for attaining the same. Please suggest an optimized solution for the same.

I have used Virtual serial port, putty and internal serial module(CCS), though last option worked well, but UART is not working indeed. Please, give me directives.

Thank you.

    Go to the product overview of the MSP430F5529 and download the code-examples for it. There is all you need to get the UART running.

    First let me thank you. I found all codes for my board as expected. Thanks again.

    However, I am having real problem with practical setup(wiring) with UART module, in that case, my doubts are, whether I need to use any hardware interface to connect my computer and board(as I have prepared RS232 interface with MAX). I have so much confusion because, I've communicated with PC on G2553 launchpad device, which never demanded any special circuit arrangement . It just take to initialize the UART module, and I have used the same cable that we use for code debugging.

    So my doubt is : " If I am right now using a really Big board..Then shouldn't be that easier than this?"

    Could CDC interface help?

    Thank you.

    How exactly is the connection made on the hardware level? If you want to use the MSP430F5529's USB connection, you have to implement a CDC interface.

    The LaunchPad uses the existing USB/SER converter that connects the debugger with the FET part of the LaunchPad, to tunnel the MSPs TTL UART signals to a virtual COM port on the PC.
    Without this 'application UART', you need to connect your MSPs TTL UART signals to the PC by other means.
    You can use a MAX3232 to convert the signal levels and connect to a real COM port on the PC, or to an USB/SER converter that provides an RS232 port. Or you buy one of the USB/SER converters with direct TTL compatible signals. Be sure that the output signals are compatible with your MSPs supply voltage. Some of the bridge chips support an external digital I/O voltage where you can connect your VCC. Others emit 5V signals and you need to take care of this.
