1.1.9.4.15 DRV_USART_WriteBuffer Function

bool DRV_USART_WriteBuffer
(
    const DRV_HANDLE handle,
    void* buffer,
    const size_t size
);

This is a blocking function that writes data over USART.

This function does a blocking write operation. The function blocks till the data write is complete. Function will return false to report failure. The failure will occur for the following reasons:

• if the handle is invalid
• if the input buffer pointer is NULL
• if the buffer size is 0

DRV_USART_Open must have been called to obtain a valid opened device handle.

true - write is successful

false - error has occurred

MY_APP_OBJ myAppObj;
uint8_t myBuffer[MY_BUFFER_SIZE];

// myUSARTHandle is the handle returned
// by the DRV_USART_Open function.

if (DRV_USART_WriteBuffer(myUSARTHandle, myBuffer, MY_BUFFER_SIZE) == false)
{
    // Error handling here
}

This function is thread safe in a RTOS application. This function should not be called from an interrupt context.
