Detailed Description

This section covers functions related to the UART peripheral.

Function Documentation

+ +

◆ __attribute__() [1/2]

+ +
+
+ + + + + + + + +
__attribute__ ((deprecated("Use watch_enable_uart to enable the UART.")) )
+
+ +

Initializes the debug UART.

+
Parameters
+ + +
baudThe baud rate
+
+
+ +
+
+ +

◆ __attribute__() [2/2]

+ +
+
+ + + + + + + + +
__attribute__ ((deprecated("Use watch_uart_puts to print to the UART, or printf to log debug messages over USB.")) )
+
+ +

Outputs a single character on the debug UART.

+

Outputs a string on the debug UART.

+
Parameters
+ + + +
cThe character you wish to output.
sA null-terminated string.
+
+
+ +
+
+ +

◆ watch_enable_uart()

+ +
+
+ + + + + + + + + + + + + + + + + + + + + + + + +
void watch_enable_uart (const uint8_t tx_pin,
const uint8_t rx_pin,
uint32_t baud 
)
+
+ +

Initializes the debug UART.

+
Parameters
+ + + + +
tx_pinThe pin the watch will use to transmit, or 0 for a receive-only UART. If specified, must be either A2 or A4.
rx_pinThe pin the watch will use to receive, or 0 for a transmit-only UART. If specified, must be A1, A2, A3 or A4 (pin A0 cannot receive UART data).
baudThe baud rate for the UART. A typical value is 19200.
+
+
+ +
+
+ +

◆ watch_uart_getc()

+ +
+
+ + + + + + + + +
char watch_uart_getc (void )
+
+ +

Receives a single byte from the UART's RX pin.

+
Returns
the received byte.
+
Note
This method will block until a byte is received!
+ +
+
+ +

◆ watch_uart_puts()

+ +
+
+ + + + + + + + +
void watch_uart_puts (char * s)
+
+ +

Transmits a string of bytes on the UART's TX pin.

+
Parameters
+ + +
sA null-terminated string containing the bytes you wish to transmit.
