Transmit data from target via serial communications interface (SCI) to host
c281xdspchiplib in Target Support Package™ TC2 software
The C281x SCI Transmit block transmits scalar or vector data in int8 or uint8 format from the C281x target's COM ports in nonreturn-to-zero (NRZ) format. You can specify how many of the six target COM ports to use. The sampling rate and data type are inherited from the input port. The data type of the input port must be one of the following: single, int8, uint8, int16, uint16, int32, or uint32. If no data type is specified, the default data type is uint8.
Note For any given model, you can have only one C281x SCI Transmit block per module. There are two modules, A and B, which can be configured through the F2812 eZdsp Target Preferences block. Many SCI-specific settings are in the DSPBoard section of the F2812 eZdsp Target Preferences block. You should verify that these settings are correct for your application. Fixed-point inputs are not supported for this block. |
SCI module to be used for communications.
This field specifies the data located at the front of the sent data package, which is not part of the data being transmitted, and generally indicates start of data. The additional package header must be an ASCII value. You may use any string or number (0–255). You must put single quotes around strings entered in this field, but the quotes are not sent nor are they included in the total byte count.
Note Any additional packager header or terminator must match the additional package header or terminator specified in the host SCI Receive block. |
This field specifies the data located at the end of the sent data package, which is not part of the data being transmitted, and generally indicates end of data. The additional package terminator must be an ASCII value. You may use any string or number (0–255). You must put single quotes around strings entered in this field, but the quotes are not sent nor are they included in the total byte count.
Note Any additional packager header or terminator must match the additional package header or terminator specified in the host SCI Receive block. |
If this option is selected, an interrupt is posted when FIFO is full, allowing the subsystem to take some sort of action.
