Configure the I2C module to transmit data to the two-wire I2C serial bus.
Note You can use this block to configure the I2C settings under the Peripherals tab of the target preference blocks for the F2808 eZdsp, and F28335 eZdsp boards. |
The I2C transmit 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.
Set the bit count to 1 through 8. The default setting is 8.
Selecting this parameter enables the transmitter to accept a STOP condition from the C280x/C2802x/C2803x/C28x3x/C2834x I2C Receive block. The default setting is disabled (not selected).
When you enable repeat mode, the I2C module retransmits the same data until it detects a stop or start condition. If you use this mode, also consider selecting Enable stop condition.
If you disable repeat mode, the I2C module operates in standard mode, sending a specific number of data values once.
The default setting is disabled (not selected).
Selecting this parameter creates a status output that indicates when the I2C transmit block is transmitting a message. The default setting is disabled (not selected).
