A simple SCPI parser for small Arduino projects.

• Small memory footprint, implemented for reduced RAM usage.
• Minimal, clean code API.
• Can process char* strings or input from any Stream interface like Serial or Ethernet.
• Flash strings (F() macro) support for lower RAM usage.

• Commands defined using stings
  E.g. "MEASure:VOLTage:DC?"
• Short and long token forms, and upper and lower case commands
  E.g. "MEASURE:VOLTAGE:DC?", "meas:VoLt:DC?"
• Numeric suffixes using the # character:
  E.g. definition : "CHANnel#:SELect"
  E.g. usage : "CHAN0:SEL", "chan5:sel", "chan13:sel"
• Comma separated parameters recognition.
• Parameters treated as text, processed by the user program.
