100: Read Analog Input Line

This command allows you to read the analog input lines on an I/O board. The number that is read

back will depend on three other things: the precision used (set with Command 101), the conversion

scale (set with Command 102), and the calibration (set with Command 103). When you want to

read the analog lines as part of a custom message such as "The temperature is ??? degrees

fahrenheit" you should use the read-analog-input special words (see words numbered 800 and

higher in Appendix B). They will allow you to read the input without all of the extra "I/O ? Line ?"

words that you won't want in your messages.

<100> b l Read a single analog line

<100> b l..l Read multiple analog lines

Parameters:

- 100 is the default command name.

- B is the I/O board number (1..2)

- L is the analog input line number (1..8)

Notes:

Multiple input lines can be read with one call to this command by entering more than one

port number here.

Example:

Command 100 works fine, but I want a nicer message when reading wind speed. 053

erases then starts programming a macro. 500 is the macro number. 036 is the command to speak a

voice message. The following numbers come from Appendix B and specify the words for the

message. Word 842 is a special word number that the controller automatically replaces with the

current reading for I/O board 1 analog line 3.

; Speak "The wind speed is (analog 3) miles per hour"
