Serial - Write HW FIFO v2

Serial - Write HW FIFO v2 — The Serial Write HW FIFO driver block configures the data that will be sent to a serial receiver.

Library

Simulink Real-Time - Speedgoat

Description

The Serial Write HW FIFO v2 driver block can write up to 4 KB of data present in the I/O module hardware buffer.

Ports

Inputs
Number of Bytes to Write

A scalar which defines how many bytes will be written to the Serial HW FIFO.

Data

A vector of 4096 elements which represents the Serial HW FIFO. Only elements from 1 to Number of Bytes to Write will be placed in the hardware FIFO, subsquent values are ignored.

Parameters

Configurable I/O Module ID

This parameter associates a code module block with a configurable I/O module setup block. Set this value to match the Module ID defined in the setup block of the required configurable I/O module.

Channel

The number of the channel which this driver block entity will access. Only one channel per driver block can be addressed. You can specify channels in the range 1-N (N = the number of channels implemented in your specific configuration file defined in the Setup block).

Sample Time

Defines the base sample time at which this driver block gets its sample hit. This parameter can also be set to -1 for inherited sample time. The units are in seconds.
