Code needed from Top Coders

Try modifying pcRead or @Robin2's Example 1 one of these other serial parsers by some Top Coders:

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 3G or '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.
• txtZyme (github) with Wokwi sim of txtZyme modified for Stepper Motor
• 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.
