Sample code to send "Hello World" from one task to another FreeRTOS

[[email protected]]

Hi, Could you send me a sample to send "Hello World!" string from sender task to receiver task?

I am using C:\Nordic_Semi\nRF5_SDK_15.0.0_a53641a\examples\ble_peripheral\ble_app_hrs_freertos\pca10056\s140\ses as a base project.

I can create two tasks correctly say senderTask and receiverTask. Now, I have difficult to create a message box and send/receive message.

I am using Embedded Studio & 64bits Window10.

Please help,Thanks,

donald

This question should have been posted in FreeRTOS forum. You should look into this API and find example in the demo app to see how it is used.

Can you compile FreeRTOS sample code:

void vAFunction( MessageBuffer_t xMessageBuffer )
{
uint8_t ucRxData[ 20 ];
size_t xReceivedBytes;
const TickType_t xBlockTime = pdMS_TO_TICKS( 20 );

    /* Receive the next message from the message buffer.  Wait in the Blocked
    state (so not using any CPU processing time) for a maximum of 100ms for
    a message to become available. */
    xReceivedBytes = xMessageBufferReceive( xMessageBuffer,
                                            ( void * ) ucRxData,
                                            sizeof( ucRxData ),
                                            xBlockTime );

    if( xReceivedBytes > 0 )
    {
        /* A ucRxData contains a message that is xReceivedBytes long.  Process
        the message here.... */
    }
}
