sendData(uint32_t data);

-

Empties the FIFO transmit buffer.

+

Places a data word into the FIFO transmit buffer. + The data word can be any length up to 32 bits. The buffer length is 64 words. + If the word was queued for sending, a bool true is returned. + If no space was available, a bool false is returned.

clearBuffer();

Clears the send buffer. Does not stop a character being sent. No return value.

Notes

This modulator includes a lowpass filter on the input bit data. This can be very effective in restricting the bandwidth of the BFSK output. This filter can be None (default) or an arbitrary FIR filter.
