Non-Arduino Serial communication simulations:
Serial Input Basics by @Robin2
- Example 1 -- Receiving single characters.
- Example 2 -- Receive several chars with an end marker.
- Example 3 -- Receive with start- and end-markers
- Example 4 -- Receiving a single number from the Serial Monitor
- Example 5 -- Receiving and parsing several pieces of data
- Example 6 -- Program to receive binary data
How to process incoming serial data without blocking by @nickgammon
- Example 1: Non-blocking line buffering -- Non-blocking line buffering
- Example 2: Serial parsing state machine -- state-machine for parsing commands. E.g.
R4500S80G3
Misc
- Serial parsing RPN/Postfix:
- pcRead by @gcjr -- one-character parsing diagnostic/control tool (w/ Simulation).
- Good Forum thread on parsing a line into tokens with strtok()
- My adaptations of @nickgammon's state-machine parser into a switch-case single-letter post-fix parser for commands and numbers. E.g.
4500R 80S 3Gor '123 24 /p`:- V1: Simple RPN number and command parsing and
- V2: RPN 4 function calculator+commands
- V3: Serial control of Stepper speed, acceleration and motion control with RPN calc -- Use Serial to control a stepper with real-time adjustment of Acceleration, Maximum speed and Position, with 4-function calculator.

- G-code parsers, commonly used in CNCs, 3Dprinters, laser cutters
- Marginally Clever G-code parser -- Accumulates a line of serial into a buffer then processes it. Written such that the parsing characters could be made non-blocking with a substitution of an 'while' with an 'if' in the
loop(){} - grbl -- buffer characters and parse on end-of-line
- Teacup 3DP firmware -- parse a character at a time
- Marlin -- parse a buffered line.

The list is an incomplete version of Arduino Built-In Examples. I think it is useful for folks that can't be bothered to wire up an example, or for folks without hardware, so they can examine the behavior of a tested working example. It might also help folks explain how one, can, for example, use the basic analog and LED examples to handle their very special devices that provide or consume digital or analog outputs.
If you know of, or want to build other simulations of the Arduino Built-In Examples, please point them out and I'll add them to this list.
If you want to discuss the dangers, failings, obvious improvements and next steps, or finer points of a particular built-in example, please start a separate forum thread for it along the lines of How to Wire and Program a Button or State Change Detection (Edge Detection) for pushbuttons and I can add that discuss to this list.
