                           int readLen)

Description copied from interface: I2CPort

High level i2c interface. Perform a complete i2c transaction and return the results. Writes the specified data to the device and then reads the requested bytes from it.

Specified by:

i2cTransaction in interface I2CPort

Parameters:

deviceAddress - The I2C device address.

writeBuf - The buffer containing data to be written to the device.

writeOffset - The offset of the data within the write buffer

writeLen - The number of bytes to write.

readBuf - The buffer to use for the transaction results

readOffset - Location to write the results to

readLen - The length of the read
