Part 32 — Analog to Digital
The Analog to Digital module in Crestron’s SIMPL programming works by taking a single 16-bit analog input value and breaking it down into 16 individual binary (digital) outputs. Each output represents one bit in the binary representation of the analog input.
Analog Input (<ain>):
This is the 16-bit integer value that you input into the Analog to Digital symbol. The value can range from 0 to 65535 (the range of a 16-bit unsigned integer).
Binary Conversion:
The module converts the 16-bit analog value into its binary (base-2) representation. For example, if <ain> has a value of 12345, its binary representation is 0011000000111001.
Digital Outputs (<bit1> to <bit16>):
Each of the 16 digital outputs represents a single bit in the binary representation of the analog input. <bit1> is the least significant bit (LSB), and <bit16> is the most significant bit (MSB).
If a bit in the binary representation is 1, the corresponding digital output will be set high (1). If the bit is 0, the digital output will be set low (0).
Output Representation:
The outputs are arranged as individual bits, with <bit16> as the highest (most significant) bit and <bit1> as the lowest (least significant) bit.
For the example input of 12345, the outputs would look like this:
<bit16>= 0<bit15>= 0<bit14>= 1<bit13>= 1<bit12>= 0<bit11>= 0<bit10>= 0<bit9>= 0<bit8>= 0<bit7>= 1<bit6>= 1<bit5>= 1<bit4>= 0<bit3>= 0<bit2>= 1<bit1>= 1
