Detailed Description

Synchronous I2C implementation.

Member Function Documentation

general_write_read()

std::vector< uint8_t > pflib::lpgbt::I2C::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.

Reimplemented in pflib::lpgbt::I2CwithMux.
