In Universal Mode, how can I display the data read back from the slave device?
  • In order to read from a slave device, the least significant bit of the
    slave address must be set to a 1. During a read operation, all of the data bytes between the slave address and the next START or STOP condition are filled in with values read from the slave. For example, to read 4 bytes from a slave at address 0x80, you would enter
            S 81 00 00 00 00 P
    as the the command sequence. The 00s are just place holders that determine how many bytes are to be read. After transmitting the command sequence, the Universal Mode window will display something like
            S 81 11 22 33 44 P
    where the 11, 22, 33, and 44 are the four values read from the slave. Transmitting the command sequence again will cause 4 more bytes to be read with the display being updated with the new values.
