UARTx_Tx_Idle
Prototype
char UARTx_Tx_Idle();
Description Use the function to test if the transmit shift register is empty or not.
Parameters None.
Returns - 1 if the data has been transmitted
- 0 otherwise
Requires Routine requires at least one UART module.
Used UART module must be initialized before using this routine. See UARTx_Init and UARTx_Init_
Advanced routines.
Example
// If the previous data has been shifted out, send next data:
if (UART1_Tx_Idle() == 1) {
UART1_Write(_data);
}
Notes UART library routines require you to specify the module you want to use. To select the desired UART
module, simply change the letter x in the routine prototype for a number from 1 to 4.
Number of UART modules per MCU differs from chip to chip. Please, read the appropriate datasheet
before utilizing this library.
