Receive responds to a basic Receive request from the master. In Return Byte Count,
enter the number of bytes a Receive request will respond with, then enter the data to
be returned in the Data array. The Basic page limits you to eight bytes of returned data.
Note:
The “x” indicates the value is a hexadecimal number. Clicking on “x” will
toggle it to a “d” indicating that the value is a decimal number.
Write simply displays the byte count and data written by the master.
Read responds to a basic Read request by the master. In Return Byte Count, enter the
number of bytes a Read request will respond with, then enter the data to be returned
in the Data array. The Basic page limits you to eight bytes of returned data.
Byte Count will display the number of bytes between the slave read address and the
slave write address. Data will display the data between the slave read address and the
slave write address.
PICkit Serial Slave Address set the slave address here you wish the software to
respond to, then press the Apply button. A confirmation message should appear on
the Transactions window.
