70 * Initialise a COM port. As supplied 2 COM ports are supported, so ulPort can
\r
71 * be either 0 or 1. Note that COM 0 is in effect USART1 in ST library
\r
72 * terminology. The baud rate can be any standard baud rate and has been tested
\r
73 * up to 115200 baud.
\r
75 long lCOMPortInit( unsigned long ulPort, unsigned long ulWantedBaud );
\r
78 * Output a single char to a COM port. As supplied 2 COM ports are supported,
\r
79 * so ulPort can be 0 or 1. Note that COM 0 is in effect USART1 in ST library
\r
80 * terminology. cOutChar is the character to be transmit, and xBlockTime is
\r
81 * the time the task should be held in the Blocked state (in ticks) for space
\r
82 * to become available in the queue of characters waiting transmission. pdPASS
\r
83 * will be returned if the character is successfully queued (possible after
\r
84 * waiting in the Blocked state for up to xBlockTime ticks), otherwise pdFAIL
\r
87 signed long xSerialPutChar( long lPort, signed char cOutChar, TickType_t xBlockTime );
\r
90 * Retrieve a character from the queue of received characters. As supplied 2
\r
91 * COM ports are supported, so ulPort can be 0 or 1. Note that COM 0 is in
\r
92 * effect USART1 in ST library terminology. pcRxedChar is the address into
\r
93 * which the received character will be copied, and xBlockTime is the time the
\r
94 * task should be held in the Blocked state (in ticks) for a character to be
\r
95 * available if one is not available immediately. pdPASS will be returned if a
\r
96 * character is successfully returned (possible after waiting in the Blocked
\r
97 * state for up to xBlockTime ticks), otherwise pdFAIL will be returned.
\r
99 signed long xSerialGetChar( long lPort, signed char *pcRxedChar, TickType_t xBlockTime );
\r
102 * Send a string of characters to a COM port. As supplied 2 COM ports are
\r
103 * supported, so ulPort can be 0 or 1. Note that COM 0 is in effect USART1 in
\r
104 * ST library terminology. pcString contains the address of the first
\r
105 * character to be transmit, and ulStringLength the total number of characters
\r
106 * from and including *pcString. pdPASS will be returned if the entire string
\r
107 * is queued for transmission successfully, otherwise pdFAIL will be returned.
\r
108 * Note that serPUT_STRING_CHAR_DELAY within STM32_USART.c can be adjusted in
\r
109 * accordance with the applications requirements. Comments are included where
\r
110 * serPUT_STRING_CHAR_DELAY is defined.
