Member Function Documentation

general_write_read()

std::vector< uint8_t > pflib::I2C_Linux::general_write_read ( uint8_t i2c_dev_addr, const std::vector< uint8_t > & wdata, int nread = 0 )

virtual

Carry out a write of zero or more bytes followed a by a read of zero or more bytes.

If either write or read is zero bytes long, it is omitted.

Exceptions

pflib::Exception

in the case of I2C communication failure

Implements pflib::I2C.

get_bus_speed()

int pflib::I2C_Linux::get_bus_speed ( )

virtual

read_byte()

uint8_t pflib::I2C_Linux::read_byte ( uint8_t i2c_dev_addr )

virtual

Read a single byte using the efficient interface.

Exceptions
