 # Vrekrer scpi parser
-Simple SCPI parser for small Arduino projects
+A simple SCPI parser for small Arduino projects.
+
+## Features
+- Small memory footprint, implemented for reduced RAM usage.
+- Minimal, clean code API.
+- Can process char* strings or input from any [Stream](https://www.arduino.cc/reference/en/language/functions/communication/stream/) interface like [Serial](https://www.arduino.cc/reference/en/language/functions/communication/serial) or [Ethernet](https://www.arduino.cc/en/Reference/Ethernet).
+- Flash strings ([F() macro](https://www.arduino.cc/reference/en/language/variables/utilities/progmem/#_the_f_macro)) support for lower RAM usage.
+
+
+## SCPI features:
+ - 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.
