Configure the I2C module to receive data from the two-wire I2C serial bus.
The I2C receive block supports the 7–Bit addressing, 10–Bit addressing, and Free data format. The default setting is 7–Bit addressing.
Select the method for setting the slave address register of the I2C slave. Selecting Specify via dialog displays Slave address register parameter. Selecting Input port enables definition of the address register via the input port. The default setting is Specify via dialog.
When you select Specify via dialog, enter a value for the Slave address register. The default value is 80. This field takes a decimal value.
Set the bit count to 1 through 8. The default setting is 8.
Set the length of the read data. The default value is 1.
Set the value the I2C node outputs to the model before it has received any data.
The default value is 0.
Select this parameter to generate a no-acknowledge bit (NACK) during the I2C acknowledge cycle and ignore new bits from the transmitting I2C node. The default setting is disabled (not selected).
Enable the I2C Receive Block in master mode to send a STOP message to the I2C Transmit block while it is in slave mode. The default setting is disabled (not selected).
Selecting this parameter creates a status output that indicates when the I2C receive block is receiving a message. The default setting is disabled (not selected).
Set the sample time for the block's input sampling. To execute this block asynchronously, set Sample Time to -1, and refer to Asynchronous Interrupt Processing for a discussion of block placement and other necessary settings. The default value is 0.001.
Type of data in the data vector. The length of the vector for the received message is at most 8 bytes. If the message is less than 8 bytes, the data buffer bytes are right-aligned in the output. You can set this parameter to int8, uint8, int16, uint16, int32, or uint32. The default setting is int8.
