1.34.27.3 1.35.21.3 USARTx_WriteIsBusy Function
C
/* x = USART instance number */
/* Non-blocking mode */
bool USARTx_WriteIsBusy( void )
Summary
Returns the write request status associated with the given USART peripheral instance.
Description
This function returns the write request status associated with the given USART peripheral instance. It can be used to check the completion status of the USARTx_Write() function when the library is configured for non-blocking (interrupt) mode. In that, the function can be used as an alternative to using a callback function to check for completion.
Precondition
USARTx_Initialize must have been called for the associated USART instance.
Parameters
None.
Returns
true - USART is busy in processing the previous write request.
false - USART is free and ready to accept a new write request.
Example
if(USART1_WriteIsBusy() == true) { //USART is currently processing the write request. } else { // write is completed. }
Remarks
None
