Parameters

source the name of a time source

Implements gr::soapy::block.

◆ start()

bool gr::soapy::block_impl::start ( )

overridevirtual

Called to enable drivers, etc for i/o devices.

This allows a block to enable an associated driver to begin transferring data just before we start to execute the scheduler. The end result is that this reduces latency in the pipeline when dealing with audio devices, usrps, etc.

Reimplemented from gr::block.

◆ stop()

bool gr::soapy::block_impl::stop ( )

overridevirtual

Called to disable drivers, etc for i/o devices.

Reimplemented from gr::block.

◆ transact_spi()

unsigned gr::soapy::block_impl::transact_spi	(	int	addr,
		unsigned	data,
		size_t	num_bits
	)

overridevirtual

Perform a SPI transaction and return the result. Its up to the implementation to set the clock rate, and read edge, and the write edge of the SPI core. SPI slaves without a readback pin will return 0.

If the device contains multiple SPI masters, the address bits can encode which master.

Parameters

addr	an address of an available SPI slave
data	the SPI data, num_bits-1 is first out
num_bits	the number of bits to clock out

Returns: the readback data, num_bits-1 is first in

Implements gr::soapy::block.
