Tool/software: Code Composer Studio

Hi,

I am trying to test sci_echoback sample code. I dont have hyperterminal software. for interfacing I am using CCS serial terminal. After running the code I'm getting response from micro controller. but I'm unable to input any character. When I type in keyboard nothing shows up in the terminal. Is there any way I can input character through terminal (or some other method that does not require any third party software installation)?

    Hi,

    I don't have a board with this device here, but my LAUNCHXL-F28027F works well here, but it has everything integrated, including the serial port itself. Other boards my require external wiring. 

    With this particular issue, are you sure the TX pin is correctly connected? Since the serial communications have no protocol, a break on this pin will silently fail and result in an inability to send data to the device. 

    Hope this helps,

    Rafael

    Hi,

    Thanks for your response. The problem got resolved after proper serial connection in the controlCard. 

    Thanks,
