MSP430F5529: Sending data to the host from MSP430

Part Number: MSP430F5529

Hi,

I have been struggling to make my own program to send the data from MSP430F5529 LaunchPad to the host over USB. All examples seem to work fine, but I ran into an issue that the data is not send if at the end of data array I do not have \n, \r or \0. I was unable to find a way how to go around this problem and did not find anyone who would have same issues (all of them were sending strings and I am sending data stream from the sensor). My question is how to send data stream from sensor that woul communicate with the MSP430 through UART and received data then parsed to the PC? I was using cdcSendDataInBackground() functions that are included in all examples.

Best Regards,

Edvardas Vysniauskas

    Hello,

    Why not read sensor data, add '\n', '\r' or '\0' into your data stream and then send it to PC through USB?

    Thank you for your reply.

    However, that does not seem to be a good solution. As far as I understand, the UART port is connected with USB port, would that mean that if I send something through UART that is directed to sensor instead of the host, it would be sent to the host as well? Is it possible to control this, which end device will receive the message if that is the case.

    create an array
    let us say something like this char TestArray[]={'Identity','Data'\n};
    the TestArrays First Field will be the identity of sensor let us say '1' and the Data be the message in char format '236' for example..This data will go to all.. On the reciever side you can read the data and identify who is sending the message with the first field of received message

    I will send the data in following format 

    TestArray[]={'10256\n'};

    '1' is the identity of the device . '0256' is the data .. and \n is t\he new line
