Description

Receive serial data from the Universal Asynchronous Receiver/ Transmitter (UART) port.

You can specify the ASCII characters for packaging your data with the additional package header and terminator. You can specify the data type and the data length that you want to receive using the block.

DMA interrupt will be used in the background for Data transfer from Receive FIFO to buffer. UART_DMARx interrupt will be triggered when any data will be received in the FIFO.

Ports

Output

Data — UART receive data

vector | scalar

Outputs the data read from the UART port.

Status — UART receive status

0 | 1 | 2 | 3 | 4 | 8

The status port outputs one of these values:

• 0 — represents no error in data reception

• 1 — represents frame error

• 2 — represents parity error

• 3 — represents data synchronization error

• 4 — represents a break in the data reception

• 8 — represents an overrun error.

Parameters

Additional package header — Prefix header

S (default)

Specify the additional package header to use as the prefix before the data packet to synchronize the data packets.

Additional package terminator — Suffix terminator

E (default)

Specify the additional package terminator to use as the suffix after the data packet to synchronize the data packets.

Data type — Type of data to be received

uint8 (default) | double | single | int8 | int8 | int16 | int32 | uint32 | boolean

Select the output data type.

Data length — Size of data to be received

1 (default) | positive integer

Specify the data length to receive.

Enable blocking mode — Enable blocking mode for data transmission

off (default) | on

Enabling this option ensures that the FIFO buffer is checked for data availability before receiving the data.

Sample time — Interval at which block reads data

0.1 (default)

Specify the sample time for receiving data. To execute this block asynchronously, set Sample Time to -1.
