Analog Initialize

The Analog Initialize symbol allows you to set the current state of an analog signal
to a specified value. The symbol behaves in two distinct ways, based on how you
configure it.
Single-Output Form:
In this configuration the symbol has multiple digital inputs and a single analog
output. Each input has a corresponding parameter. When a digital input goes high
(that is, on the rising-edge) the analog output will take on the value specified by the
parameter corresponding to that digital input. Due to the nature of analog signals in
general, the analog output will maintain this value until this symbol or another
symbol explicitly changes its value.
This form of the Analog Initialize is very useful to allow an analog signal to take on
different values throughout the course of a running program. As an example, let's say
that we want to create a number of TV channel preset buttons, where each button is
responsible for changing the tuner to a specific channel. One way to accomplish this
would be to use an Analog Initialize symbol with a digital input for each preset
channel you want. In the example shown below, we are introducing an additional
symbol, called the Decade, which is handy for decoding an analog value into its
hundreds, tens, and units digits. This is especially useful when dealing with an IR-
controlled device that expects individual keypad commands, as we are assuming in
this example. For more information on the Decade symbol, please consult the
SIMPL Windows help file.
