Implement mwx::stream and input/output with UART0 of TWELITE.
Serial object is initialized at system startup with UART0, 115200 bps, and the initialization process is performed in the library. On the user code, it is available from setup().Serial1 object is provided in the library, but no initialization process is performed; to enable UART1, perform the necessary initialization procedures Serial1.setup(), Serial1.begin().Output may become unstable during setup(), wakeup() just after startup or flush process just before sleep.
Initialize objects.
Serial(UART0) will automatically call setup() in the library. There is no need for a user call.
Also, the buffer size of Serial (UART0) is determined at compile time. You can change it by the macro MWX_SER_TX_BUFF (768 if not specified) or MWX_SER_RX_BUFF (256 if not specified).
| Parameter | Description |
|---|---|
buf_tx |
FIFO buffer size for TX |
buf_rx |
FIFO buffer size for RX |
Initialize hardware.
The Serial (UART0) has an automatic begin() call in the library. No user call is required.
| Parameters | Description |
|---|---|
speed |
Specifies the baud rate of the UART. |
config |
When the serial_jen::E_CONF::PORT_ALT bit is specified, UART1 is initialized with DIO14,15. If not specified, initializes UART1 with DIO11(TxD),9(RxD). |
The last two digits of the specified baud rate are rounded to zero. Also, due to hardware limitations, there may be an error from the specified baud rate.
When specifying 9600, 38400, or 115200, the baud rate is calculated without division. See constexpr uint16_t _serial_get_hect_baud(uint32_t baud) for details of processing.
(Not implemented) Stop using hardware.
Get a structure in the TWE_tsFILE* format used in the C library.
In Serial (UART), the _sSerial structure is defined.
