Member Function Documentation

read_spi()

virtual uint32_t uhd::spi_iface::read_spi ( int  which_slave, const spi_config_t &  config, uint32_t  data, size_t  num_bits  )

virtual

Read from the SPI bus.

Parameters

which_slave	the slave device number
config	spi config args
data	the bits to write out (be sure to set write bit)
num_bits	how many bits in data

Returns

spi data

transact_spi()

virtual uint32_t uhd::spi_iface::transact_spi ( int  which_slave, const spi_config_t &  config, uint32_t  data, size_t  num_bits, bool  readback  )

pure virtual

Perform a spi transaction.

Parameters

which_slave	the slave device number
config	spi config args
data	the bits to write
num_bits	how many bits in data
readback	true to readback a value

Returns

spi data if readback set

write_spi()

virtual void uhd::spi_iface::write_spi ( int  which_slave, const spi_config_t &  config, uint32_t  data, size_t  num_bits  )

virtual

Write to the SPI bus.

Parameters

which_slave	the slave device number
config	spi config args
data	the bits to write
num_bits	how many bits in data
