Accessing iNEMO from an embedded linux device

has anybody tried accessing the iNEMO board from an embedded linux device using the usb interface? I am able to power the iNEMO from my device and also able to load a usb-serial driver. What I don't know is the correct serial interface parameters to use to open the port. I hope that somebody in this forum has already gone through this exercise.

thx!

You can find useful information in the ''UM1017: STEVAL- MKI062V2 communication protocol'' available at ww.st.com/inemo.

Hi Fabio,

I've read that document which is very helpful but I could not find any mention of serial parameters i need to use to open the port like (baud rate, data bits, stop bit, parity and flow control) settings.

regards.

There are no favorite settings for the virtual com over the usb (if you want you can set the bps 115200 and 8N1 with no control flow: hothese values are not used)

Best Regards

The following code works for me:

========

    int     fd;

    struct  termios inemo;

    if((fd = open(port, O_NOCTTY|O_RDWR)) < 0){

        perror(''open'');

        _exit(errno);

    }

    tcgetattr(fd, &inemo);

    inemo.c_iflag &= ~(IGNBRK | BRKINT | PARMRK | ISTRIP | INLCR | IGNCR | ICRNL | IXON);

    inemo.c_oflag &= ~OPOST;

    inemo.c_lflag &= ~(ECHO | ECHONL | ICANON | ISIG | IEXTEN);

    inemo.c_cflag &= ~(CSIZE | PARENB);

    inemo.c_cflag |= CS8;

    tcsetattr(fd, TCSANOW, &inemo);

I was able to access the inemo board now. It turned out that I need to modify my usb2serial driver. Thx for the help anyways.
