3. Receive serial data as a string with SerialIn() or SerialInRecord().
Example:
SerialInRecord(Com2,SerialInString,42,0,35,"",01)
o Declare the string variable large enough to accept the string.
Example:
Public SerialInString As String * 25
o Observe the input string in the input string variable in a numeric monitor
(p. 521).
Note SerialIn() and SerialInRecord() both receive data. SerialInRecord() is
best for receiving streaming data. SerialIn() is best for receiving discrete
blocks.
4. Parse (split up) the serial string using SplitStr()
o Separates string into numeric and / or string variables.
o Example:
SplitStr(InStringSplit,SerialInString,"",2,0)
o Declare an array to accept the parsed data.
Example:
Public InStringSplit(2) As String
Example:
Public SplitResult(2) As Float
7.9.17.5.3 Serial I/O Output Programming Basics
Applications with the purpose of transmitting data to another device usually
include the following procedures. Other procedures may be required depending on
the application.
1. Open a serial port with SerialOpen() to configure it for communications.
o Parameters are set according to the requirements of the communication
link and the serial device.
o Example:
SerialOpen(Com1,9600,0,0,10000)
o Designate the correct port in CRBasic.
o Correctly wire the device to the CR1000.
o Match the port baud rate to the baud rate of the device in CRBasic.
o Use a fixed baud rate (rather than auto baud) when possible.
2. Build the output string.
o Example:
SerialOutString = "*" & "27.435" & "," & "56.789" & "#"
o Tip — concatenate (add) strings together using & instead of +.
o Tip — use CHR() instruction to insert ASCII / ANSI characters into a
string.
