void TangoSendMessageNoHeader(unsigned char
idRepeat)
idRepeat, a specified number of times
None.
The TangoSendMessageNoheader service triggers
transmission of a message containing Preamble, ID,
Length, Data, Checksum and EOM fields. The ID field is
transmitted idRepeat+1 times.
This service is used to send messages using the 'No
Header Detect' format described in
Without Header Detect on page
be called only when the Romeo2 RX IC is configured to
not use header bytes (i.e., the option
ROMEO_HE_VALUE is set to 0 in the Romeo.h header
file).
void TangoTimerInterrupt(void)
None
This function controls the actual processing of the Tango3
driver. It is called by the interrupt vector of the timer
channel used to generate data for the Tango3 IC. In the
CodeWarrior parameter file, this interrupt vector must be
directed to this function. This function MUST be included
used to ensure proper operation of the software driver.
