Serial Communication between Labwindows and Kinetis

kharsha — Thu, 15 Mar 2018 09:04:12 GMT

Using kinetis Design Studio ,Processor Expert , how to do serial communication from LabWindows ?

I am creating a GUI in LabWindows which will be sending & receiving characters via the serial port with Kinetis K10 processor. Unfortunately unable to do so. could anyone please suggest a way to solve the issue ?

Thanks in advance.

Kinetis Processor Expert Code :

in main.c

/* this is used when receiving data , currently commented out*********/

//volatile bool DataReceivedFlg = FALSE;
//unsigned char InpData[10];

/******** to send a character**********/

unsigned char OutData[] = "1";

LDD_TError Error;
LDD_TDeviceData *MySerialPtr;

int main(void)

{

PE_low_level_init();
MySerialPtr = AS1_Init(NULL);
for(;;) {

Error = AS1_SendBlock(MySerialPtr, OutData, sizeof(OutData));
WAIT1_Waitms(100);

}

LabWindows Code:

bytes_read = ComRd(comport,buf,2);

CopyString (tbox_read_data, 0, buf, 0, bytes_read);
SetCtrlVal (panelHandle, PANEL_TBOX_READ, tbox_read_data);

every time "buf" is empty .

Hello K HARSHA,

Sorry I don't know the Labwindows well.

While I recommend you firstly use a serial terminal (Putty or others )

to check whether the send data can work well.

Hope it helps

Have a great day,

Hi Alice ,

Sorry for the trouble, but could you please tell me if the code snippet for sending the character I have used is correct . I wanted to know if there is any other way to do so.

Thanks in advance.

Harsha.

Hello ,

Yes, there is no error in your sending code.

I rememberd you said it can work well :

About the usage of Serail_LDD, there are demo code you can refer to:

Hope it helps
