Detailed Description

Universal asynchronous receiver transmitter (UartHal4)

Not available on the low- and medium density devices.

Very basic implementation that exposes more hardware features than the regular Usart classes.

Member Enumeration Documentation

inheritedstrong

Enum Values	Documentation
ParityError	Call interrupt when a parity error occurred.
TxEmpty	Call interrupt when transmit register is empty (i.e. the byte has been transfered to the shift out register.
TxComplete	Called when the byte was completely transmitted.
RxNotEmpty	Call interrupt when char received (RXNE) or overrun occurred (ORE)

inheritedstrong

Enum Values	Documentation
TxEmpty	Set if the transmit data register is empty.
TxComplete	Set if the transmission is complete.
RxNotEmpty	Set if the receive data register is not empty.
OverrunError	Set if receive register was not cleared.
FramingError	Set if a de-synchronization, excessive noise or a break character is detected.
ParityError	Set if a parity error was detected.

static void modm::platform::UartHal4::enable ( )

inlinestatic

Enables the clock, resets the hardware

inlinestatic

static void modm::platform::UartHal4::read ( uint8_t & data )

inlinestatic

Saves the value of the receive register to data

Warning: This method does NOT do any sanity checks!! It is your responsibility to check if the register contains something useful!

static void modm::platform::UartHal4::write ( uint16_t data )

inlinestatic

Write a single byte to the transmit register.

Warning: This method does NOT do any sanity checks!! It is your responsibility to check if the register is empty!
