FreeMASTER serial communication routines.

Function Documentation

void FMSTR_ProcessSCI ( void )

Handle SCI communication (both TX and RX)

This function checks the SCI flags and calls the Rx and/or Tx functions

Note:: This function can be called either from SCI ISR or from the polling routine

FMSTR_BOOL FMSTR_Rx ( FMSTR_BCHR nRxChar )

Handle received character.

Parameters:

nRxChar The character to be processed

Handle the character received and -if the message is complete- call the protocol decode routine.

Finalize transmit buffer before transmitting.

Parameters:

nLength - response length (1 for status + data length)

This Function takes the data already prepared in the transmit buffer (inlcuding the status byte). It computes the check sum and kicks on tx.

FMSTR_BOOL FMSTR_Tx ( FMSTR_U8 * pTxChar )

Output buffer transmission.

Parameters:

pTxChar The character to be transmit

get ready buffer(prepare data to send)
