Function Documentation

◆ msg_state_init()

void msg_state_init ( msg_state_t *  s)

Initialize an msg_state_t struct before use.

This resets the entire state, including all callbacks. Remember to use this function to initialize the state before calling rtcm3_process() for the first time.

Parameters
sState structure

◆ rtcm3_clear_callbacks()

void rtcm3_clear_callbacks ( msg_state_t *  s)

Clear all registered callbacks.

This is probably only useful for testing but who knows!

◆ rtcm3_find_callback()

rtcm3_msg_callbacks_node_t * rtcm3_find_callback ( msg_state_t *  s,
u16  msg_type 
)

Find the callback function associated with a message type.

Searches through the list of registered callbacks to find the callback associated with the passed message type.

Parameters
msg_typeMessage type to find callback for
Returns
Pointer to callback node (rtcm3_msg_callbacks_node_t) or NULL if callback not found for that message type.

Definition at line 224 of file rtcm3.h.

References p, and s.

Referenced by rtcm3_process(), rtcm3_register_callback(), and ubx_process().

+ Here is the caller graph for this function:

◆ rtcm3_process()

s8 rtcm3_process ( msg_state_t *  s,
unsigned char  buff 
)

Read and process RTCM3 messages.

Reads bytes from an input source using the provided read function, decodes the RTCM3.

When an RTCM3 message is successfully received then the list of callbacks is searched for a callback corresponding to the received message type. If a callback is found then it is called with the ID of the sender, the message length and the message payload data buffer as arguments.

Note
rtcm3_process will always call read with n > 0 (aka it will attempt to always read something)

The supplied read function must have the prototype:

u32 read(u8 *buff, u32 n, void* context)

where n is the number of bytes requested and buff is the buffer into which to write the received data, and context is the arbitrary pointer set by rtcm3_state_set_io_context. The function should return the number of bytes successfully written into buff which may be between 0 and n inclusive, but must never be greater than n.

Note that rtcm3_process may not read all available bytes from the read function so the caller should loop until all bytes available from the input source have been consumed.

Parameters
sState structure
readFunction pointer to a function that reads n bytes from the input source into buff and returns the number of bytes successfully read.
Returns
RTCM_OK (0) if successful but no complete message yet, RTCM_OK_CALLBACK_EXECUTED (1) if message decoded and callback executed, RTCM_OK_CALLBACK_UNDEFINED (2) if message decoded with no associated callback, and RTCM_CRC_ERROR (-2) if a CRC error has occurred. Thus can check for >0 to ensure good processing.
