Serial Receive Block

The Serial Receive block reads data from the specified serial port. It will continue to output the last received value until new data is read.

Inputs

Sim Input: Optional bytes data that will be passed through in simulation mode

bytes: bytes received from the port.
Is Valid: A boolean representing whether the data is valid as determined by the Stale Age (ms) param

Baud Rate (default = 9600): Baud rate to use
Port (default = "/dev/ttyUSB0"): Port to connect to
Start Delimiter (default = "$"): String or bytes that indicate the start of a message. For a bytes literal, escape the characters using \x (i.e. \x20 for the unicode ' ' corresponding to the hexadecimal value 0x20).
End Delimiter (default = "\r\n"): String or bytes that indicate the end of a message.
Read Fixed Bytes (default = 0): Fixed number of bytes to read after Start Delimiter. If this is set to a non-zero value it will take precedence over End Delimiter
Stale Age (ms) (default = 1000): Age from last valid data received when the block will output Is Valid as False
