Function Documentation
| void serial_baud | ( | serial_t * | obj, |
| int | baudrate | ||
| ) |
Configure the baud rate.
- Parameters:
-
obj The serial object baudrate The baud rate to be configured
| void serial_break_clear | ( | serial_t * | obj ) |
Clear the break.
- Parameters:
-
obj The serial object
| void serial_break_set | ( | serial_t * | obj ) |
Set the break.
- Parameters:
-
obj The serial object
| void serial_clear | ( | serial_t * | obj ) |
Clear the serial peripheral.
- Parameters:
-
obj The serial object
| void serial_format | ( | serial_t * | obj, |
| int | data_bits, | ||
| SerialParity | parity, | ||
| int | stop_bits | ||
| ) |
Configure the format.
Set the number of bits, parity and the number of stop bits
- Parameters:
-
obj The serial object data_bits The number of data bits parity The parity stop_bits The number of stop bits
| void serial_free | ( | serial_t * | obj ) |
Release the serial peripheral, not currently invoked.
It requires further resource management.
- Parameters:
-
obj The serial object
| int serial_getc | ( | serial_t * | obj ) |
Get character.
This is a blocking call, waiting for a character
- Parameters:
-
obj The serial object
| void serial_init | ( | serial_t * | obj, |
| PinName | tx, | ||
| PinName | rx | ||
| ) |
Initialize the serial peripheral.
It sets the default parameters for serial peripheral, and configures its specifieds pins.
- Parameters:
-
obj The serial object tx The TX pin name rx The RX pin name
| void serial_irq_handler | ( | serial_t * | obj, |
| uart_irq_handler | handler, | ||
| uint32_t | id | ||
| ) |
The serial interrupt handler registration.
- Parameters:
-
obj The serial object handler The interrupt handler which will be invoked when the interrupt fires id The SerialBase object
| void serial_irq_set | ( | serial_t * | obj, |
| SerialIrq | irq, | ||
| uint32_t | enable | ||
| ) |
Configure serial interrupt.
This function is used for word-approach
- Parameters:
-
obj The serial object irq The serial IRQ type (RX or TX) enable Set to non-zero to enable events, or zero to disable them
| void serial_pinout_tx | ( | PinName | tx ) |
Configure the TX pin for UART function.
- Parameters:
-
tx The pin name used for TX
| void serial_putc | ( | serial_t * | obj, |
| int | c | ||
| ) |
Send a character.
This is a blocking call, waiting for a peripheral to be available for writing
- Parameters:
-
obj The serial object c The character to be sent
| int serial_readable | ( | serial_t * | obj ) |
Check if the serial peripheral is readable.
- Parameters:
-
obj The serial object
- Returns:
- Non-zero value if a character can be read, 0 if nothing to read
| void serial_set_flow_control | ( | serial_t * | obj, |
| FlowControl | type, | ||
| PinName | rxflow, | ||
| PinName | txflow | ||
| ) |
Configure the serial for the flow control.
It sets flow control in the hardware if a serial peripheral supports it, otherwise software emulation is used.
- Parameters:
-
obj The serial object type The type of the flow control. Look at the available FlowControl types. rxflow The TX pin name txflow The RX pin name
| int serial_writable | ( | serial_t * | obj ) |
Check if the serial peripheral is writable.
- Parameters:
-
obj The serial object
- Returns:
- Non-zero value if a character can be written, 0 otherwise.
